I once unknowingly fed a singular 18650 cell directly with a 5v2a supply. It was like a small grenade went off in the room followed by a small fire that was thankfully easily extinguished. A year later I'm boarding a flight with my phone, a rather beefy battery bank, and some other electronic devices in my carry-on that were all perfectly acceptable to bring with me but they wouldn't let me take my half tube of toothpaste. I just remember thinking to myself "I feel like there're enough batteries in my carry-on devices to cut a plane in half, but for some reason the toothpaste is the scary thing?"
I agree with the video 100%. Unplug the charger when not in use. Give the charger a chance to cool down. I noticed that most electronics work better when they’re unplugged and plugged back in (resets, recycles, I’m not really sure). I also only charge my battery when it’s around 50% or below and I never charge in direct sunlight. Try to keep your charger in a cool and dry place. Try not to allow the charger to get wet. Simple precautions that go a long way.
@@OddJobzAberdeenshire I see this subject is like many others-ask 100 people the same question and you get 100 different answers. I have 3 scooters and whatever I’m doing to maintain the batteries is working so I’ll keep doing what I’ve been doing.
Seeing these fires happening through multiple sources has absolutely changed my mind about buying an E bike along with buying an E CAR .. I don't want to own anything that could spontaneously combust , especially knowing the fact that you can't put the fire out when it does ..to me that makes owning these electric vehicles extremely dangerous to have in my garage or near my home or near my other vehicles.. and as I've seen extremely dangerous to just go out for a ride ..
What causes most of these Ebike Battery Lithium Fires, is when one of the Cells (some batteries have over 72 cells) Gets Out of balance.. Low quality BMS, can cause the cell voltage to get out of balance.. if you have a choice, always opt for the higher quality BMS.. Using a low quality Charger that doesn't assess and balance the voltage of each cell in the pack can also do this.. In Battery packs with multiple cells, the BMS is supposed to balance the voltage of each cell.. When it doesn't, the higher voltage cell (ie: 58.8v) and the lower voltage cell in the pack (ie: 51.1v) there is a rush of amps flowing to the lower voltage cell. That causes the cells to heat up to dangerous levels igniting fires.. (these Lithium Fires are almost impossible to put out with a standard A, B, or C type extinguisher) Ways to avoid this dangerous situation, 1) fully charge the battery with a quality charger like the Grin CycleSatiator. This charger looks at each cell to make sure the BMS is doing it's job... 2) Fully charging every time will normally balance the cells voltage in the pack.. At the very least, Fully Charge the pack at least every other time.. 3) if something is wrong with your packs BMS or Cells, the pack will get hot during charging (so feel the pack while charging) 4) if your pack is used in freezing weather, or freezes, always bring it inside to let it warm to room temp..Never attempt charging a frozen battery pack.. it is dangerous.. I top my packs off after every ride.. (I use a Grin CycleSatiator) The GrinCS, tapers off (slows down the charge at the very end) This preserves the battery...Most cheap chargers don't taper the charge at the end..And my packs never get out of balance.. I have been riding for 6 years, with dual battery balancers. And i get more mileage out of my packs at over 2k cycles.. I have put on over 12k miles in that 6 years.. And i don't loose range because of these reasons.. Understand how charging works and how to safely charge your packs..
Nothing has caught on fire here except for your amazing sense of humor and all the dad jokes. Dude I was really laughing out loud. I am a 70 year old 5th grader at heart. Oh, also GREAT information too. You should have been on laugh-in. Love the channel! Tod in Vegas :)
There are a few other really important things that really improve safety: 1 Charge outside where ever possible. In a yard, on a balcony. This reduces the risk of your home catching fire, buys you time and reduces the chance of you inhaling toxic smoke. 2 Charge on a fire proof surface. On a paving slab, in a sink, somewhere that will not catch and spread the fire. Think about what is above the location where you charge. 3 Never be tempted to recharge the battery in your can and leave it while you go for a walk/coffee. This has written off a number of cars. 4 Keep a bucket of sand near your preferred (hopefully outside) charging location. Pretty much nothing puts the fires out except smothering them in sand so have it close to hand. Last year in a dry period one of our batteries was damaged and caught fire, the person was alone and the fire caught the grass. It ended with a serious bush fire in a protected area and the consequences are still on-going.
If you are going to charge your lithium battery outside, you should heat it with an ebike battery warmer when it's cold outside. Cold temperatures reduce lifespan when charging
I wondered about batter fires after hearing about beings electric jet catching on fire from a lithium ion batter yes upon that with passengers and every thing. The planes do not fly with electricity but the controls are battery operated. My instrument instructor who was a fully certified pilot said every landing is really a controlled crash yes scary but accurate. Bad battery means no controls a landing that is converted into an out of control crash? Noosiree Bob not for this duckies. Wel that issue was fixed no crashes just a potential so not so bad. The on-board alternators a jet can make gobs of power remember after one engine is started the engines alternator easily starts another engine all by itself. And to start a jet the turbine has to spin really really fast. Passenger planes have an APU. Auxiliary Power unit for in flight emergencies they can start a jet engine the the electricity made by that engine can start any other addition engines.
I built a small brick walled charging station with a solar panel where I do all my charging. Contained safe area. I tend to trust 1S devices more than any larger voltage stacks that require more complicated BMS/charger management.
I know someone that dropped a wrench accidentally on a battery that was big enough to melt the wrench in half in one binding pop flash! Scary VERVERY VERY SCARY!!!!!
Great Topic! The chargers have abilities to get on fire as well. Last year phantom recalled charger because of the issue. I like the charger with fan inside as they are little loud but turn off once battery charged. That way you know it's done ✔️
In this video, we'll discuss ebike battery fires Some preventative measures timer: amzn.to/3eSSYNV box: amzn.to/3MPdEmA bat-safe: amzn.to/3MQGqDs Check out the largest ebike battery I've tested: ruclips.net/video/FpxybxuJ1eE/видео.html
I love my 20"x4" fat tire folding electric bike, I've had it one year. I always unplug mine, when the batteries sync, I immediately unplug it. It's not a cheap battery, 48 volt 13 AH. Runs my 500 watt, 1000 peak watt motor at 25 mph easily. At 155# I can get 60+ miles on a 3 hour charge. I just subscribed, I appreciate your knowledge and experience, the best to you and your family. Thank you.
Important information in this video. Much appreciated. If people follow your advice, there would be far less incidents. I have 2 adult ebikes (well over 5 years on original batts), a Jetson bolt and an emove touring scooter. I have an electric golf cart caddy that totes my clubs for me (battery going on 5 years). My mower, weedwhacker, blower are all electric. I never charge overnight and have had no issues thus far. Thanks again for putting this info out.
Well aware of all the downsides to sla batteries, but as an older guy who jumped on this e moped scene 20 yrs back when nobody knew what they were and constantly getting pulled over. Now they had to be replaced every couple yrs, but that was the bulk of the $$ maintenance and are still being sold on some today... ie Xtreme Cabo. Now I have a new one, they suck compared to the ones from 10 yrs back, the lower the battery gets the slower I go after 6-8 miles. Lots of downsides. But never thought about fire issues. I can cheaply replace and or rebuild myself, have over amped for yrs and never saw any heat issues or fires. Shortens the life of the motor at most. Keep thinking about a lithium battery pack as an upgrade, but for me 4-5 miles is all I need in my small town. As someone with epilepsy can't get a license to drive anything, but still have to get around
If you look close enough, you can pretty much find a "concern" for EVERYTHING. Cell phone battery explosions, laptop fires, bikes getting stolen, falling off the cliff while mountatin climbing, crashing while driving, etc, etc. There's a risk to every one of these. Stolen ebikes are a common thing, but that doesn't deter me from buying one. I have a decently reliable bike lock and I don't leave the bike out of my sight in a public for a long period of time. Yes, this means that I'll have to change a few habits and be more responsible, but that comes with owning a bike, no? I appreciate the mindful tips of the video. I just find it frustrating when people let these risks get to their head and spread their fears on to other people.
LOL, Thanks for in information. My first eBike arrives Friday! ;-) Love your humor sprinkled throughout the presentation. the only device I have had battery issues with so far has been my smart phones. Two have had the batteries swell up after a few year of being on their chargers overnight every night. No flames yet but I have since changed my charging habits with my new phones to only when needed. ;-)
I have a set of 4x16ah multistar lipo batteries in my home made mid drive 60V, they have been in my bike since 2015 and are still balanced to within 0.060 with over 7k miles I have the bms set to cut when any 1 cell reaches 4.2 and 3.3 and have never had a problem. My batteries are only 2 parallel, I think personally that flat cells are safer being folded as to a roll in a metal case.
Oh get over yourself. It's a rarity that this happens. It's likely those building at bottom dollar and abusing the pack. Don't overload...offer shock/impact protection in use and u are diminishing odds further.
Nice tips man. I usually charge my ebike inside my trunk in the evening pligged into a lithium power station. I usually unplug it when its fully charged just in case for safety. Thanks again and great video too.
Vibration and impact are a strong contributor to battery pack fires. It only takes one 3.7v cell in a 48v pack to become dented or damaged, for the whole pack to fail catastrophically. Store and charge your suspect battery in a metal file cabinet or barbecue.
@@mikemorgan8588 Phewwww. Yeah I use it in a fairly large lunch bag and hook it up to my rear rack using those rubber tarp straps. It's been great so far. It's a 52v pushing 45amps but I lowered the amperage on my controller to 36amps. So less heat and a bit more range.
My workpllace has a lot of hand tools that have lithium batteries, and the guys leave the chargers plugged in 24-7 and leave batteries just sitting on the charger long after being fully charged, bugs the hell out of me as I know the failure of a 5 cent part in the charger etc that is part of what stops the charging when full- can FAIL, and then the battery gets "cooked" sitting on that charger over night, over the weekends etc. All it takes is one little part to fail and the battery gets "cooked" ANother bad thing is they carelessly take the batteries and toss them in a bag etc with all the rest of their tools, hand drivers, screw drivers, screw bits and other metal tools and it only takes one bad movement in there to short out two terminals on a battery and you have a fire in the bag that spreads!
If you going to upgrade, make sure the controller matches specs of battery and motor. It is a serious concern if you go out the range of every specs, especially the battery. It's simple math you have to read and applying. There are battery of having specs for 52v 20ah but there are various ones of the amps for different motor or controller. Must stick to the specs when upgrading.
I used a 52v that pushes 45amps. On a 48v sabvoton controller that takes 45amps. But I reduce the AMPS to 36. For more range and less heat. On a 48v 1500w rear hub motor. Will I have any issues?
@@Mash3OH3 So you have a 52v battery with 45a continuous rating, a 48v 45a controller, a 1500w rated hub motor (all together effectively capable of pushing 2300+watts), And you reduce your amps to get more range and deal with less heat? Why would you buy those components just a ride around restricted? If you want range and less power, Buy weaker components! Reducing amps artificially is not really an efficient way anyway, You'll gain better from a weaker bike. And to answer your issues question: No you shouldn't have any, I just think it's pointless gimping your set up lol
I became very critical towards electric cars and bikes. I think we still need to learn a few years, until this problem is mastered better. BTW. Taco Bell failed here in Singapore. That thing with the bell is such a nonsense. In particular, if you sell only junk.
The issue isnt we need to "learn" more, the issue is we are buying cheaply made junk, poor quality control batteries made in CHINA- the land of toxic drywall, poisoned pet treats and baby formula, blatantly forged CARB certifications on laminated flooring shipped to Lumber liquidators and... need I go on? Also, SOME shady people have been selling "refurbished" or repaired E-bike batteries etc in NYC and elsewhere that they took apart and repaired and offered for sale for half price, there's those and numerous videos on youtube showing how to REPAIR all kinds of these Lithium batteries from the smaller ones used for hand tools like drills and drivers to the E-bike batteries, the videos show step by step instructions by UNTRAINED, NON factory trained amateurs who take apart the battery case and then start messing around with the electronics inside, and also replacing individual cells that went bad. They show how to solder in the new cells and fix the boards, trouble is- they may have gotten lucky and many people dont follow instructions, you get someone repairing their battery after watching a video and they do one little thing wrong or poorly solder a new cell or the wrong one into the pack and there's no telling what can happen, these batteries have too much energy in them for amateurs to be in there messing around with tools and a soldering gun! There is a video on a science channel I follow "nile red", the guy carefully took the case off a lithium battery about the size of an "A" cell, and unrolled the lithium foil and tossed the lithium foil into a pan of water on the floor, it sparked in the water and then ignited into a flame, and then most unexpectedly- it EXPLODED with enough force it looked and sounded like an M80 firecracker and blew the flame out along with moving the pan and spraying the water all over, and that was just about a 2 foot long unrolled strip of lithium foil! It's highly reactive to contact with water.
You have made some good issues. I recommended to everyone, after the use of an ebike with the battery, they should holder off for a few hours before charging, less possible issues. Otherwise after you charged should wait a while before using. These are my own issues and I have probably 50 different LiPo batteries use and not ever had any issues, from many different things I use and yet, lol... Good luck to everyone! -Fred
You are right I had many powerful ebike like 15000watt fat tire ebike 200amp controller 120kmh and I never had any problems with battery 🔋 Is catching on fire 🔥 because I always let my battery cool down before charging it is a 72.v60ah and keep in mind all of these battery 🔋 comes from China good battery just makes sure you do the right thing when charging your battery
@@THouse-md1hy I'd like to add to this statement. I have a 52v 45amp battery purchased from a place called Conhis motor. Haven't had any issues with it. I've recently lowered the amperage on my controller from 45amps to 36amps. For less heat buildup. But I do like to top up my battery at random intervals at coffee shops. Not sure if that's okay or not.
LiFePo4 batteries contain lithium iron phosphate, it's a SAFER and cheaper battery, my Vtoman Jump 1,000 battery inverter has this battery, the older batteries will fade away as they get replaced by these newer ones.
Do not charge hot battery,wait let it rest before and after use one hour. When the charging is complete the voltage of the battery are the same,so the current doesn't flow any more,this is safe. Avoid cheap batterys with powerful 2000W motors,be aware of strong 5A or more chargers.
I bought a Jetson Bolt. It does take about 4-5 hours to charge, but I watch it. All the fire hype has scared me into keeping it outside, where it could get stolen, even locked up in my back yard.
If you get a good pack, it should have a BMS with overcharge protection. The batteries I use have a standalone charge circuit and BMS, meaning the battery knows the current independent of the controller, and stops charging when full, but the charger has overcharge circuitry as well, meaning redundant safeties. I also added a thermal fuse, which is a slightly higher amperage than the speed controller, so if it does begin to runaway it should de-energize the system when the fuse burns. I also try to stick to full charge discharge cycles. I don't fully deplete the range, but when it begins to crawl I let it charge to full, then gradually discharge over days. Continuous re=charging Li-ion will degrade stamina more quickly over 1000 cycle lifespan. Haven't had any sort of fire or shorts with these batteries, but back when I was a master technician for a popular tech repair franchise, we had a few venting incidences that set off the smoke alarms and I had to intervene and chuck the battery or device outside to burn. Frankly I'm thankful to still have all my fingers...terror is grabbing a venting MacBook Pro Retina battery "squid" and lobbing it like a grenade into the parking lot where it pops and melts a hole in the asphalt from the ensuing fire. That particular incident, I had warned a fellow technician not to use metal tools and he tried to use his iSesamo tool anyway with some isopropyl to loosen the adhesive. Best I can figure, he nicked the pack, then with the heat and prying it tore/mixed the layers and it puffed up and vented quickly. The entire lobby filled with a really sweet-smelling white smoke. Managed to save the customer's machine by acting quickly and doing what I did, but by all means DO NOT DO what I did. Lifelong burn scars and other possible injuries just aren't worth it if faced with an imminent venting cell: just prevent fire exposure as best you can and try to put some distance between the pack and yourself or structures if thermal runaway is unavoidable.
These are huge in NYC, they have had many fires and deaths. The government should regulate these companies and make the manufacturer make the chargers shut off when they are charged like a battery tender.
Been having my ebike w similar battery for a couple of years now with many charges, no problems!🤞🏽 Now my lipo’s for my quadcopters? , had to sprint towards door with smoking batt too many times lol
I heard a really good recommendation once: Charge them in an outdoor Grill, Fireplace or Oven! Most batteries burst under high stress either while charging or while being drained quickly. What's the one place at home designed for fire? That's right, your fireplace, chimney or outdoor grill. Maybe your Oven as well. If a battery fire happens in one of those places, nothing will happen because the structure is designed for high heat fires! Just don't use them for their intended purpose while you charge your batteries there 😉
I got a e-bike on Thursday and woke up Friday morning to it catching fire, it wasn’t on charger it was just in the middle of my garage. Thankfully my insurance is taking care of everything, they’re looking into it right now.
I typically keep my battery fully charged before I go to bed. There seems to be two safeguards that include the power switch on the bike and the automatic switch in the charger. Sometimes I plug in the charger and the battery recognizes it and switches on. When the battery is full it turns off along with the charger. I know this is not fool proof. A 3 hour timer would be perfect as my charger doesn't get hot until about 2 hours into a charge and that's when I watch it closely with an applied heat sink on the charger.
I write firmware for BLDC motors that are used in scooters. One important firmware function is to derate motor performance (torque) against battery temperature so that the battery temperature remains below its operational max. This is better than just killing the motor once you reach the maximum battery temperature as it keeps the scooter going and the battery cooler.
Hi!Bosch ebike charger will stop charging ons battery full, if you will let it plugged (for any reason)If some off cell drop charge little then will start changing and disconnect again when full.I believe if product been manufactured with safety in mind and tested risk is relatively low.
I was told never leave your battery unattended when charging. New battery technology can be dangerous. Not like the days of ni-cads when you could leave them on the charger over night
I am all for lipo with supercapacitors(of course don't forget the big metal box and balancing your cells) really when it gets down to it just treat the battery like a piece of tofu 😅
I am surprised at these ebikes exploding driving down the road! I have been building battery packs & working with hundreds of 18650 batteries, E-pen batteries & Thank God I have not had a fire yet! I think a lot of it has to do with the quality of the batteries & like you said..." when recycled the welding marks ect". It causes a lot of damage to the batteries. Bottom line! When in doubt recycle it! Don't charge it. Don't fiddle with it And definitely don't try to build it! Drain the power out of it and recycle it.
The cell quality's kinda minor in all fairness. The three big reasons for a lithium battery becoming a bomb are over-charge, over-current and short circuiting. My bet is some of the fires while in use are from shoddily insulated packs, or from packs made from cells that can't handle the high rates of discharge, since there is that chance that a pack being discharged too rapidly will heat up and thermally runaway as of it's overcharged.
Today, while driving my crane to do a job on a busy (for Idaho) freeway, I got passed by a SUV with a couple hub drive cargo bikes on a hitch. A few miles later I saw brake lights go on, it seems they had lost one bike and it had already been run over. I had to swerve to miss it but it was already ruined, no fire though! On another crane job, a large house had burned down, the reason I was told, was a Milwaukee tool charging station/batteries, don't know the details other than that. I charge my own ebikes in my concrete floored shop, using chargers that auto shut off, usually to 80 or 90%, and also at a low amp rate (Chi chargers). I also have a DC converter, custom built, that allows me to charge the ebike I carry in my small plane, at a bit less then 2 amps, into a quality pack with a good BMS, so far so good. I put ebike fires, when using good euipment properly, right up there with getting struck by lightening.
1:25 I know this is sarcasm but if battery fire occurs in cargo there is no way to put them out. That is why passenger aircrafts forbids batteries in cargo compt. If they go off on a passenger plane, you have SOME chance to put them out. There is also whr restriction, but it doesnt look like they're enforced well... so thats TSA/FAA issue. Internal short - this is most likely due to no-brand companies reusing used cells or factory rejects. This is combined with poor spotweld or lack of protection against vibration (eg. Cells not contained in racks. This increases exposure to vibration). Chargers generally would not overcharge the battery if designed properly (for example, 120vac rectified comes just around 84v, so it is impossible to overcharge a 72v battery unless a diode fails and there is no fuse in place). The explosion during charge is most likely due to aformentioned poor cell quality. Spot weld issue - Very true, but you can simply use bigger sized/capacity cells to mitigate this. LiFePO4 cells - they are actually quite capable for ebike propulsion, but their size/shape makes it very hard to customize shape unlike 18650/21700 cells.
Just started the video... I'm going to assume the increase of fires are from people not knowing how to modify their bikes with bigger batteries, quality parts, and not considering higher amps means you need thicker wires and higher volts increase the chances of a short.
These chargers really should give an option to limit charge to say 80% state of charge (phones should too for that matter.) Or, it's time box-in-the-middle gizmos are made that go between the charger and the battery which cease charging after a certain time, or amp hours, or voltage/current, or several of these measurements. Manual timers make a lot of sense for a quick, cheap, easy and fairly effective insurance policy.
I live in a place where it gets down below 0⁰F so it's not safe to charge a battery out side. My idea in to charge the battery in a self cleaning oven. Of course not on the clean cycle or on. A self cleaning oven is designed to handle very high heat. Like a shut-off timer is a good idea too. If the battery catches fire the oven should be able to contain the fire at least until the fire department gets there. Fairly simple and no cost. A gas barbeque outside when above 32⁰F is another idea. The news locally of these e-fires is getting scary. Maybe some safety regulations are needed.
USING A I HOUR TIMER REALLY HELPS, AS I SIT ON MY COMPUTER I USE ME MY 1 HOUR TIMER IT GOES OFF ,I GO CHECK TO SEE IF THE RED LITE HAS TURNED GREEN IF NOT I LEAVE FOR ONE MORE HOUR. DEPENDS ON HOW FAR YOU WENT YOU MAY NEED THREE HOURS.
Like with almost all things, it takes multiple failures usually to have a bad day. With ebikes, the batteries and the charger are the main issues. Cheapo batteries could be of poor construction and maybe not good BMS or even no BMS. If the battery pack is cheapo, you can bet the charger is cheapo too. I agree using a large ammo box and/or a timer is a great idea. Those military surplus ammo boxes are made to handle explosions from inside and made to be durable and fireproof. As for a timer, you could use a simple mechanical plug timer or a "smart plug" or even go so far as setting up a way to measure the battery level and using it to determine when to shut off the power to the charger. If you want as safe as possible (for your home at least), think about detached shed with power running to it and always keep the ebike and components in the shed and never in the home. That way, worse comes to worse, you lose a shed and an ebike but not your house and everything in it. On a side note, lithium iron phosphate batteries are old school? Where have I been. I never heard of them until the last few years. They seem like a nice next progression overall for lithium ion batteries. Of course, we really need to find a way to have a safe batter with a high energy density that uses commonly available materials and not use lithium.
Great video! but I just want to stress that I don't think most people understand how much energy is stored in a typical E bike's battery. Take my add motor M81 it has if I use throttle only at least a 30 mile range it's an 80 pound bike and I weigh 200 pounds so just stop and think about how much energy we have stored in that battery think about the energy that you would have to expand pushing the pedals to bike 30 miles on an £80 bike if you weighed 200 pounds! Now imagine the equivalent energy stored in that battery because that's what you have should its short circuit catastrophically it could discharge some or all of that energy essentially at once so my recommendation is to never even think about leaving of charging Ebike unattended and whatever you do don't try to open up your battery pack and modify it or use a charger that didn't come with it unless you are a certified electronics technician familiar with charging and battery circuits. and again thank you for the great video
sometimes the reasons why it just because lock of knowledge in electrical and electronic " or wrong wiring undersize of wire and fuses can cause fire or not in Standards" or they can not use compatible charger to the battery" or they can not USE BMS ' sometimes overcharging but there is a Solution there's was a timer plug now that you can buy on the Shopping store " to prevent overcharging you can set the timer for how many hours you charge it and it will automatically turn off
6:27 dont most batteries come with a bms which prevents over voltage, under voltage and also the battery charger itself detects that that the battery cells are 4.2v per cell so it should cut power to the battery. Usually chargers are indicated by an Led light which would tell whether your battery is charging or is fully charged.
Thanks for the reminder in over charging a battery. I made up a list of devices that I charge periodically and found it was 14! This includes to 2 ebikes, computers, walkie talkies, portable tire pumps etc. I use my cell phone timer to check hourly to see if the item is fully charged. Now with the ebikes I mostly charge the battery on the ebike in the "house". Why not in the garage, simple Answer live in Arizona where the garage temp is well over a 100 degrees which is not to compatible with charging. Question, do I need life insurance? Ebikes in the house is not a good for a match made in heaven. Or should I get rid of the complainer?
I just time my charge to check every 1/2 hr. then check Battery level... I don't wait for the green light and have no problems... I use my e-bike for local trips around town, maybe 5 miles... The Charger can get very HOT so I put it on top of a small white plate, glass dish...
A charged Li batt has everything it needs for a fire. Unlike gasoline or diesel, cutting off its air won't stop the fire. Likelihood of a gire is different than severity of that fire.
My e bike battery not in use is stored in metal tool box with zip loc plastic bags of silica sand . The battery is charged to 80 or 90% on a luna charger on a timer . Next is store the battery in the shed in a cement fire board box .
This question has not come up here yet: What about the Lectric brand folding bikes, that keep the single battery INSIDE of a heavy steel tube? It can be charged inside the bike or out of it. How could it get enough air to burn if inside of all that steel? I charge with the battery out anyway, and keep it separate from the bike while parked inside. I would never leave a charging battery behind. Thanks for all of the good advice---I subbed!................................elsullo
How does a bullet get enough 'air' to burn inside of its brass casing? The answer is that gun powder and batteries produce the oxygen they need to burn via their chemistry which makes for a self sustaining fire due to them containing both fuel and oxidizer. Thermite is another product that produces a self sustaining fire.
i use similar cells for my ciggarette vapourizer, ive heard about them exploding in unregulated devices, fortunately my devices are regulated and no nasty acciedents.
A lot if not a majority of e-bike batteries are made in such a way that there is significant pressure on the nickel conductors. Over time, vibrations can wear through insulators and..
I've never had a battery explode or catch fire during normal charging or use, in-part because I test and calibrate my charging equipment regularly, but also because I use quality BMS boards and I never use cheap e-bay / Aliexpress cells. I always go with a reputable wholesaler because that way I can confirm that the datasheets will be 100% accurate, the cells will be of good quality and that the only way to make them go boom is to force too much voltage in, or too much current out of the cells... Or stab them!!
I purchased a 52v 45amp battery that apparently uses Grade A LG Cells 21700. They're called Conhis Motor. Do you by chance know if they're reputable or not?
@@Mash3OH3 I've not heard if that manufacturer... Best way to find out if they're truthful though is open the pack up and inspect the cells. Make sure the cell wrappers and labelling are correct and see if you can run a capacity check to ensure the real capacity is close to advertised. While you're in there take a multimeter and measure each bank of cells and verify that they're well balanced and that your over voltage protection kicks in no later than 4.25v. Your cells should settle back to 4.2v when charged. If not, replace the BMS before use. I would recommend getting an ANT BMS since that will also give you live performance readouts and extremely detailed charge and discharge control over the pack.
I use a smart plug, then you can just use the app on your phone to set a time for the plug to shut off. That way it's not on all night. Some of these batteries can take up to 8 hours to charge.
I've been riding an Ebike and charging ebike batteries since 2019, and I've never had a problem. Yes the charger I use gets hot when its charging, but its only a 2 amp hour charger. And when the battery is charged, the charger cools off, and I unplug it. I have left a battery charging over night, in my house, and it does not bother me. I think the biggest problem is people trying to fast charge the battery with the wrong charger. I've learned that if you slow charge your battery, it will last longer. Plus, I do not tinker with any of the controls. Just my two cents worth.
@@StromLxrd6 Both ebike battery chargers I have are 2 amp hour chargers, yes slow but steady and I've never had a issue. The problem is most people are in a hurry, so they buy an after market charger that is maybe 4+ amps per hour and this is where you get into trouble. My two chargers get hot but not to a point of danger, when I use them to charge a battery. If I tried to use a 4 amp hour charger, I can only imagine just hot hot that would get. Plus I'm forcing a bigger charge into the battery then maybe its built in BMS, I think that's it, can handle, and thus BOOM. So there you go.
The battery on my Hitway from almost dead charges in 6 hours. I set a timer on my phone and unplug it as soon as l get a green light. The battery was room temp with only the charger slightly warm to the touch.
All airplanes should have a steel case with fireproof mittens in them that they can throw a laptop or cell phone into in the event that it burns. Should be an international law. I use an ammo box and an old steel Milwaukee sawzall case at home for my batteries.
I gave an old computer to a friend and he would leave it plugged in while wandering the internet. One day, at the Library, it finally had had enough and it smoked enough to set off the fire alarms. A guard knocked it out of his hands (he was trying to set it down) and rushed everyone out. An hour or two later, we came back in to find that it had eaten an impressive amount of carpet. We collected our stuff and they shut down for two days.
I bought a Luna charger and use to charge my e batteries to 80 or 90 % . Using a lamp timer on brick in case the battery is warm and only charging when i’m home . I store the batteries in a metal tool box with find sand bags under and on top of the battery with smoke alarm . After charging I let the cells balance for a hour or more be use . I do this for peace of mind and What's Causing Ebikes Fires? precaution . I never seen any information on Lectric XP bike battery problems .
The battery shown in the image that has a silver casing with black top and bottom is a battery Im trying to find .Any idea who makes it .I have one thats dead on my daymak bike and cant find a replacement . Its a 10 yr. old bike and nothing on their website.
Not one mention of impacting a battery. Breaking in a New Battery, or pushing a new battery to the max. most batteries have a proprietary charger that won't allow them to overcharge the battery.
I've had a e bike for 8 years
Knock on wood no issues yet .it's never failed me and still works oerfect .

I've recently purchased a 52v 45amp battery from conhis motor. Works great so far. Hopefully it stays that way
I once unknowingly fed a singular 18650 cell directly with a 5v2a supply. It was like a small grenade went off in the room followed by a small fire that was thankfully easily extinguished. A year later I'm boarding a flight with my phone, a rather beefy battery bank, and some other electronic devices in my carry-on that were all perfectly acceptable to bring with me but they wouldn't let me take my half tube of toothpaste. I just remember thinking to myself "I feel like there're enough batteries in my carry-on devices to cut a plane in half, but for some reason the toothpaste is the scary thing?"
Yep you’re allowed take a 36v 10ah battery on the plane… equivalent to multiple grenades. But 9 out of 10 dentists agree tootpaste is dangerous😂😂😂
@VelEire_ I'm told 100w or 150w with permission per battery up to 3 batteries. Thpugh they never say anything about laptop battery 🤷🏻♂️
The number of planes brought down each year by toothpaste has no measure.
@@VelEire_ just the gas smoke from one would poison all in the plane. You make a good point.
@@neilstern7108Not a good point bc they can simply drop the emergency O2 masks for everyone to breath instead.
I agree with the video 100%. Unplug the charger when not in use. Give the charger a chance to cool down. I noticed that most electronics work better when they’re unplugged and plugged back in (resets, recycles, I’m not really sure). I also only charge my battery when it’s around 50% or below and I never charge in direct sunlight. Try to keep your charger in a cool and dry place. Try not to allow the charger to get wet. Simple precautions that go a long way.
It's recommended to charge your battery after every ride to prolong its life.
@@OddJobzAberdeenshire I see this subject is like many others-ask 100 people the same question and you get 100 different answers. I have 3 scooters and whatever I’m doing to maintain the batteries is working so I’ll keep doing what I’ve been doing.
Seeing these fires happening through multiple sources has absolutely changed my mind about buying an E bike along with buying an E CAR .. I don't want to own anything that could spontaneously combust , especially knowing the fact that you can't put the fire out when it does ..to me that makes owning these electric vehicles extremely dangerous to have in my garage or near my home or near my other vehicles.. and as I've seen extremely dangerous to just go out for a ride ..
What causes most of these Ebike Battery Lithium Fires, is when one of the Cells (some batteries have over 72 cells) Gets Out of balance.. Low quality BMS, can cause the cell voltage to get out of balance.. if you have a choice, always opt for the higher quality BMS.. Using a low quality Charger that doesn't assess and balance the voltage of each cell in the pack can also do this..
In Battery packs with multiple cells, the BMS is supposed to balance the voltage of each cell.. When it doesn't, the higher voltage cell (ie: 58.8v) and the lower voltage cell in the pack (ie: 51.1v) there is a rush of amps flowing to the lower voltage cell. That causes the cells to heat up to dangerous levels igniting fires.. (these Lithium Fires are almost impossible to put out with a standard A, B, or C type extinguisher)
Ways to avoid this dangerous situation, 1) fully charge the battery with a quality charger like the Grin CycleSatiator. This charger looks at each cell to make sure the BMS is doing it's job... 2) Fully charging every time will normally balance the cells voltage in the pack.. At the very least, Fully Charge the pack at least every other time.. 3) if something is wrong with your packs BMS or Cells, the pack will get hot during charging (so feel the pack while charging) 4) if your pack is used in freezing weather, or freezes, always bring it inside to let it warm to room temp..Never attempt charging a frozen battery pack.. it is dangerous..
I top my packs off after every ride.. (I use a Grin CycleSatiator) The GrinCS, tapers off (slows down the charge at the very end) This preserves the battery...Most cheap chargers don't taper the charge at the end..And my packs never get out of balance.. I have been riding for 6 years, with dual battery balancers. And i get more mileage out of my packs at over 2k cycles.. I have put on over 12k miles in that 6 years.. And i don't loose range because of these reasons..
Understand how charging works and how to safely charge your packs..
good advice. i have the lunacycle advanced 48v charger. and it slows down when its fully charged.
Nothing has caught on fire here except for your amazing sense of humor and all the dad jokes. Dude I was really laughing out loud. I am a 70 year old 5th grader at heart. Oh, also GREAT information too. You should have been on laugh-in. Love the channel! Tod in Vegas :)
There are a few other really important things that really improve safety:
1 Charge outside where ever possible. In a yard, on a balcony. This reduces the risk of your home catching fire, buys you time and reduces the chance of you inhaling toxic smoke.
2 Charge on a fire proof surface. On a paving slab, in a sink, somewhere that will not catch and spread the fire. Think about what is above the location where you charge.
3 Never be tempted to recharge the battery in your can and leave it while you go for a walk/coffee. This has written off a number of cars.
4 Keep a bucket of sand near your preferred (hopefully outside) charging location. Pretty much nothing puts the fires out except smothering them in sand so have it close to hand.
Last year in a dry period one of our batteries was damaged and caught fire, the person was alone and the fire caught the grass. It ended with a serious bush fire in a protected area and the consequences are still on-going.
If you are going to charge your lithium battery outside, you should heat it with an ebike battery warmer when it's cold outside. Cold temperatures reduce lifespan when charging
Great post. I charge outside except winter. Unplug immediately after the batteries sync. My battery is made in the USA. Not cheap either.
I wondered about batter fires after hearing about beings electric jet catching on fire from a lithium ion batter yes upon that with passengers and every thing.
The planes do not fly with electricity but the controls are battery operated. My instrument instructor who was a fully certified pilot said every landing is really a controlled crash yes scary but accurate. Bad battery means no controls a landing that is converted into an out of control crash? Noosiree Bob not for this duckies. Wel that issue was fixed no crashes just a potential so not so bad. The on-board alternators a jet can make gobs of power remember after one engine is started the engines alternator easily starts another engine all by itself. And to start a jet the turbine has to spin really really fast. Passenger planes have an APU. Auxiliary Power unit for in flight emergencies they can start a jet engine the the electricity made by that engine can start any other addition engines.
I built a small brick walled charging station with a solar panel where I do all my charging. Contained safe area. I tend to trust 1S devices more than any larger voltage stacks that require more complicated BMS/charger management.
I know someone that dropped a wrench accidentally on a battery that was big enough to melt the wrench in half in one binding pop flash! Scary VERVERY VERY SCARY!!!!!
Great Topic! The chargers have abilities to get on fire as well. Last year phantom recalled charger because of the issue. I like the charger with fan inside as they are little loud but turn off once battery charged. That way you know it's done ✔️
right the lunacycle chargers are good at this,
Right. I own one that gets almost too hot to touch. I imagine if there settles a bit of dust inside, whatever, that might be the start.
In this video, we'll discuss ebike battery fires
Some preventative measures

Check out the largest ebike battery I've tested: ruclips.net/video/FpxybxuJ1eE/видео.html
Exploding defective batteries are probably from sabotage from the oil industry.
Rather use the original old sulfuric acid batteries like one for a motorcycle with an alternator to keep the battery charged.
Fires only happen when the battery packs are made poorly. Also some people use the wrong chargers. Can’t wait for the sea salt battery this year
@@ka2rwp those are garbage batteries
I love my 20"x4" fat tire folding electric bike, I've had it one year. I always unplug mine, when the batteries sync, I immediately unplug it. It's not a cheap battery, 48 volt 13 AH. Runs my 500 watt, 1000 peak watt motor at 25 mph easily. At 155# I can get 60+ miles on a 3 hour charge. I just subscribed, I appreciate your knowledge and experience, the best to you and your family. Thank you.
Important information in this video. Much appreciated. If people follow your advice, there would be far less incidents. I have 2 adult ebikes (well over 5 years on original batts), a Jetson bolt and an emove touring scooter. I have an electric golf cart caddy that totes my clubs for me (battery going on 5 years). My mower, weedwhacker, blower are all electric. I never charge overnight and have had no issues thus far. Thanks again for putting this info out.
Well aware of all the downsides to sla batteries, but as an older guy who jumped on this e moped scene 20 yrs back when nobody knew what they were and constantly getting pulled over. Now they had to be replaced every couple yrs, but that was the bulk of the $$ maintenance and are still being sold on some today... ie Xtreme Cabo. Now I have a new one, they suck compared to the ones from 10 yrs back, the lower the battery gets the slower I go after 6-8 miles. Lots of downsides. But never thought about fire issues. I can cheaply replace and or rebuild myself, have over amped for yrs and never saw any heat issues or fires. Shortens the life of the motor at most. Keep thinking about a lithium battery pack as an upgrade, but for me 4-5 miles is all I need in my small town. As someone with epilepsy can't get a license to drive anything, but still have to get around
If you look close enough, you can pretty much find a "concern" for EVERYTHING. Cell phone battery explosions, laptop fires, bikes getting stolen, falling off the cliff while mountatin climbing, crashing while driving, etc, etc. There's a risk to every one of these. Stolen ebikes are a common thing, but that doesn't deter me from buying one. I have a decently reliable bike lock and I don't leave the bike out of my sight in a public for a long period of time. Yes, this means that I'll have to change a few habits and be more responsible, but that comes with owning a bike, no?
I appreciate the mindful tips of the video. I just find it frustrating when people let these risks get to their head and spread their fears on to other people.
Life is dangerous with a 100% chance of death. Might as well have some fun.
@@MmmHuggles George Carlin said it best: "Where's your sense of adventure? Take a f*cking chance. Buncha' g*damn pussies."
LOL, Thanks for in information. My first eBike arrives Friday! ;-) Love your humor sprinkled throughout the presentation. the only device I have had battery issues with so far has been my smart phones. Two have had the batteries swell up after a few year of being on their chargers overnight every night. No flames yet but I have since changed my charging habits with my new phones to only when needed. ;-)
I have a set of 4x16ah multistar lipo batteries in my home made mid drive 60V, they have been in my bike since 2015 and are still balanced to within 0.060 with over 7k miles I have the bms set to cut when any 1 cell reaches 4.2 and 3.3 and have never had a problem. My batteries are only 2 parallel, I think personally that flat cells are safer being folded as to a roll in a metal case.
I am about to buy an ebike.
*And this video is a wake up call, and a life saver.
Thank-you! Thank-you!
🙏💐
Oh get over yourself. It's a rarity that this happens. It's likely those building at bottom dollar and abusing the pack. Don't overload...offer shock/impact protection in use and u are diminishing odds further.
You present information in an easy way to understand and in a easy relaxed manner. Thank you…
Nice tips man. I usually charge my ebike inside my trunk in the evening pligged into a lithium power station. I usually unplug it when its fully charged just in case for safety. Thanks again and great video too.
Vibration and impact are a strong contributor to battery pack fires. It only takes one 3.7v cell in a 48v pack to become dented or damaged, for the whole pack to fail catastrophically.
Store and charge your suspect battery in a metal file cabinet or barbecue.
Or a safe but remove all the cash first...Hmmm, i wonder if a Ebike/Scooter battery could blow the doors off from the outside of a safe ? Hmm haha!
Okay not you're scaring me cause I hook up my battery to my rear rack. And my roads can get bumpy and potholes.
@@Mash3OH3 , Dropping or crashing are the things to worry about. The battery is designed for bumpy roads.
@@mikemorgan8588
Phewwww. Yeah I use it in a fairly large lunch bag and hook it up to my rear rack using those rubber tarp straps. It's been great so far.
It's a 52v pushing 45amps but I lowered the amperage on my controller to 36amps. So less heat and a bit more range.
@@Mash3OH3 Sounds like a good setup that still has speed.
Every home , apartment has an oven just put battery in oven ( off of coarse) & charge it in there it fire proof enough for battery in case..
I use my legs to power my bike. No batteries to worry about.
Sometimes my legs burn after a couple thousand meters of climbing, but my pasta and beer recharges are trouble free.
Great video. Some batteries stop charging, but its always best to just set a timer and unplug when its full.
My workpllace has a lot of hand tools that have lithium batteries, and the guys leave the chargers plugged in 24-7 and leave batteries just sitting on the charger long after being fully charged, bugs the hell out of me as I know the failure of a 5 cent part in the charger etc that is part of what stops the charging when full- can FAIL, and then the battery gets "cooked" sitting on that charger over night, over the weekends etc.
All it takes is one little part to fail and the battery gets "cooked"
ANother bad thing is they carelessly take the batteries and toss them in a bag etc with all the rest of their tools, hand drivers, screw drivers, screw bits and other metal tools and it only takes one bad movement in there to short out two terminals on a battery and you have a fire in the bag that spreads!
If you going to upgrade, make sure the controller matches specs of battery and motor. It is a serious concern if you go out the range of every specs, especially the battery. It's simple math you have to read and applying. There are battery of having specs for 52v 20ah but there are various ones of the amps for different motor or controller. Must stick to the specs when upgrading.
I used a 52v that pushes 45amps. On a 48v sabvoton controller that takes 45amps. But I reduce the AMPS to 36. For more range and less heat.
On a 48v 1500w rear hub motor.
Will I have any issues?
@@Mash3OH3 So you have a 52v battery with 45a continuous rating, a 48v 45a controller, a 1500w rated hub motor (all together effectively capable of pushing 2300+watts), And you reduce your amps to get more range and deal with less heat? Why would you buy those components just a ride around restricted? If you want range and less power, Buy weaker components! Reducing amps artificially is not really an efficient way anyway, You'll gain better from a weaker bike. And to answer your issues question: No you shouldn't have any, I just think it's pointless gimping your set up lol
I became very critical towards electric cars and bikes. I think we still need to learn a few years, until this problem is mastered better.
BTW. Taco Bell failed here in Singapore. That thing with the bell is such a nonsense. In particular, if you sell only junk.
The issue isnt we need to "learn" more, the issue is we are buying cheaply made junk, poor quality control batteries made in CHINA- the land of toxic drywall, poisoned pet treats and baby formula, blatantly forged CARB certifications on laminated flooring shipped to Lumber liquidators and... need I go on?
Also, SOME shady people have been selling "refurbished" or repaired E-bike batteries etc in NYC and elsewhere that they took apart and repaired and offered for sale for half price, there's those and numerous videos on youtube showing how to REPAIR all kinds of these Lithium batteries from the smaller ones used for hand tools like drills and drivers to the E-bike batteries, the videos show step by step instructions by UNTRAINED, NON factory trained amateurs who take apart the battery case and then start messing around with the electronics inside, and also replacing individual cells that went bad.
They show how to solder in the new cells and fix the boards, trouble is- they may have gotten lucky and many people dont follow instructions, you get someone repairing their battery after watching a video and they do one little thing wrong or poorly solder a new cell or the wrong one into the pack and there's no telling what can happen, these batteries have too much energy in them for amateurs to be in there messing around with tools and a soldering gun!
There is a video on a science channel I follow "nile red", the guy carefully took the case off a lithium battery about the size of an "A" cell, and unrolled the lithium foil and tossed the lithium foil into a pan of water on the floor, it sparked in the water and then ignited into a flame, and then most unexpectedly- it EXPLODED with enough force it looked and sounded like an M80 firecracker and blew the flame out along with moving the pan and spraying the water all over, and that was just about a 2 foot long unrolled strip of lithium foil! It's highly reactive to contact with water.

You are a very smart person, your content is excellent
Agreed! Hope he talked about nta helmets too, cpsc helmets aren't that safe and there're new nta helmets out there like xnito or bern
You have made some good issues. I recommended to everyone, after the use of an ebike with the battery, they should holder off for a few hours before charging, less possible issues. Otherwise after you charged should wait a while before using. These are my own issues and I have probably 50 different LiPo batteries use and not ever had any issues, from many different things I use and yet, lol... Good luck to everyone! -Fred
You are right I had many powerful ebike like 15000watt fat tire ebike 200amp controller 120kmh and I never had any problems with battery 🔋 Is catching on fire 🔥 because I always let my battery cool down before charging it is a 72.v60ah and keep in mind all of these battery 🔋 comes from China good battery just makes sure you do the right thing when charging your battery
@@THouse-md1hy
I'd like to add to this statement. I have a 52v 45amp battery purchased from a place called Conhis motor.
Haven't had any issues with it. I've recently lowered the amperage on my controller from 45amps to 36amps. For less heat buildup.
But I do like to top up my battery at random intervals at coffee shops. Not sure if that's okay or not.
LiFePo4 batteries contain lithium iron phosphate, it's a SAFER and cheaper battery, my Vtoman Jump 1,000 battery inverter has this battery, the older batteries will fade away as they get replaced by these newer ones.
Do not charge hot battery,wait let it rest before and after use one hour.
When the charging is complete the voltage of the battery are the same,so the current doesn't flow any more,this is safe.
Avoid cheap batterys with powerful 2000W motors,be aware of strong 5A or more chargers.
bro i dont even have a battery but the sound effects kept me watching the whole thing lmao keep it up
I bought a Jetson Bolt. It does take about 4-5 hours to charge, but I watch it. All the fire hype has scared me into keeping it outside, where it could get stolen, even locked up in my back yard.
You bought a cheap toy EV a 300 buck bike? What do you expect of the quality?
I wouldn't worry about it getting ripped off...
@@robcrissinger776 It was bought to gap the 3 mile walk to the Transit train's first run at 4 am. My Catalytic Converter was Stolen.
HAHAHAHAHA "like eating too much Taco Bell" the deadpan delivery on this channel is great.
If you get a good pack, it should have a BMS with overcharge protection. The batteries I use have a standalone charge circuit and BMS, meaning the battery knows the current independent of the controller, and stops charging when full, but the charger has overcharge circuitry as well, meaning redundant safeties.
I also added a thermal fuse, which is a slightly higher amperage than the speed controller, so if it does begin to runaway it should de-energize the system when the fuse burns.
I also try to stick to full charge discharge cycles. I don't fully deplete the range, but when it begins to crawl I let it charge to full, then gradually discharge over days. Continuous re=charging Li-ion will degrade stamina more quickly over 1000 cycle lifespan.
Haven't had any sort of fire or shorts with these batteries, but back when I was a master technician for a popular tech repair franchise, we had a few venting incidences that set off the smoke alarms and I had to intervene and chuck the battery or device outside to burn. Frankly I'm thankful to still have all my fingers...terror is grabbing a venting MacBook Pro Retina battery "squid" and lobbing it like a grenade into the parking lot where it pops and melts a hole in the asphalt from the ensuing fire.
That particular incident, I had warned a fellow technician not to use metal tools and he tried to use his iSesamo tool anyway with some isopropyl to loosen the adhesive. Best I can figure, he nicked the pack, then with the heat and prying it tore/mixed the layers and it puffed up and vented quickly. The entire lobby filled with a really sweet-smelling white smoke.
Managed to save the customer's machine by acting quickly and doing what I did, but by all means DO NOT DO what I did. Lifelong burn scars and other possible injuries just aren't worth it if faced with an imminent venting cell: just prevent fire exposure as best you can and try to put some distance between the pack and yourself or structures if thermal runaway is unavoidable.
A battery safe can be expensive. I found a 120mm mortar ammo box for $35 online. Pretty cheap for peace of mind.
You can get an auto timer to turn off the charger. Simple fix and you can set for multiple time lengths.
*"it's just better policy to avoid the plane catching on fire"* 🤣 Words to live my friend... words to live by.
These are huge in NYC, they have had many fires and deaths. The government should regulate these companies and make the manufacturer make the chargers shut off when they are charged like a battery tender.
Been having my ebike w similar battery for a couple of years now with many charges, no problems!🤞🏽 Now my lipo’s for my quadcopters? , had to sprint towards door with smoking batt too many times lol
one hot flight!
Can relate! I throw the puffy batts away now. Learned my lesson. Lol. Now I have to worry about my e-bike…damn!
like your video when you said use a timer cut out i have 2 timers have a nice day colin uk
I heard a really good recommendation once:
Charge them in an outdoor Grill, Fireplace or Oven!
Most batteries burst under high stress either while charging or while being drained quickly.
What's the one place at home designed for fire?
That's right, your fireplace, chimney or outdoor grill.
Maybe your Oven as well.
If a battery fire happens in one of those places, nothing will happen because the structure is designed for high heat fires!
Just don't use them for their intended purpose while you charge your batteries there 😉
I got a e-bike on Thursday and woke up Friday morning to it catching fire, it wasn’t on charger it was just in the middle of my garage. Thankfully my insurance is taking care of everything, they’re looking into it right now.
I typically keep my battery fully charged before I go to bed. There seems to be two safeguards that include the power switch on the bike and the automatic switch in the charger. Sometimes I plug in the charger and the battery recognizes it and switches on. When the battery is full it turns off along with the charger. I know this is not fool proof. A 3 hour timer would be perfect as my charger doesn't get hot until about 2 hours into a charge and that's when I watch it closely with an applied heat sink on the charger.
I turn a fan on to keep the battery and charger cool while charging. I think I will go with the timer idea though. Just for safety.
I write firmware for BLDC motors that are used in scooters. One important firmware function is to derate motor performance (torque) against battery temperature so that the battery temperature remains below its operational max. This is better than just killing the motor once you reach the maximum battery temperature as it keeps the scooter going and the battery cooler.
Thank you for the battery info and the stand-up comedy AAAAA
Hi!Bosch ebike charger will stop charging ons battery full, if you will let it plugged (for any reason)If some off cell drop charge little then will start changing and disconnect again when full.I believe if product been manufactured with safety in mind and tested risk is relatively low.
Cinder block and a couple of patio tiles. Old ones work as good as new ones. Yes, I am cheap but it's better than being crispy👻🔥
I was told never leave your battery unattended when charging. New battery technology can be dangerous. Not like the days of ni-cads when you could leave them on the charger over night
Thank you for the information. I didn't know there was a timer plug. I'll have to buy one because I do have a Ebike.
The new personality joke got me good you got a new sub
lithium fires can not be put out with water however maybe you can keep the battery cool enough to limit the spread of the fire.
yeah, I could have sworn talking about how it is a chemical fire, edited too fast, smh
I am all for lipo with supercapacitors(of course don't forget the big metal box and balancing your cells) really when it gets down to it just treat the battery like a piece of tofu 😅
I am surprised at these ebikes exploding driving down the road!
I have been building battery packs & working with hundreds of 18650 batteries, E-pen batteries & Thank God I have not had a fire yet!
I think a lot of it has to do with the quality of the batteries & like you said..." when recycled the welding marks ect".
It causes a lot of damage to the batteries.
Bottom line! When in doubt recycle it!
Don't charge it. Don't fiddle with it And definitely don't try to build it!
Drain the power out of it and recycle it.
The cell quality's kinda minor in all fairness. The three big reasons for a lithium battery becoming a bomb are over-charge, over-current and short circuiting.
My bet is some of the fires while in use are from shoddily insulated packs, or from packs made from cells that can't handle the high rates of discharge, since there is that chance that a pack being discharged too rapidly will heat up and thermally runaway as of it's overcharged.
Today, while driving my crane to do a job on a busy (for Idaho) freeway, I got passed by a SUV with a couple hub drive cargo bikes on a hitch. A few miles later I saw brake lights go on, it seems they had lost one bike and it had already been run over. I had to swerve to miss it but it was already ruined, no fire though! On another crane job, a large house had burned down, the reason I was told, was a Milwaukee tool charging station/batteries, don't know the details other than that. I charge my own ebikes in my concrete floored shop, using chargers that auto shut off, usually to 80 or 90%, and also at a low amp rate (Chi chargers). I also have a DC converter, custom built, that allows me to charge the ebike I carry in my small plane, at a bit less then 2 amps, into a quality pack with a good BMS, so far so good. I put ebike fires, when using good euipment properly, right up there with getting struck by lightening.
1:25 I know this is sarcasm but if battery fire occurs in cargo there is no way to put them out. That is why passenger aircrafts forbids batteries in cargo compt.
If they go off on a passenger plane, you have SOME chance to put them out. There is also whr restriction, but it doesnt look like they're enforced well... so thats TSA/FAA issue.
Internal short - this is most likely due to no-brand companies reusing used cells or factory rejects. This is combined with poor spotweld or lack of protection against vibration (eg. Cells not contained in racks. This increases exposure to vibration).
Chargers generally would not overcharge the battery if designed properly (for example, 120vac rectified comes just around 84v, so it is impossible to overcharge a 72v battery unless a diode fails and there is no fuse in place). The explosion during charge is most likely due to aformentioned poor cell quality.
Spot weld issue -
Very true, but you can simply use bigger sized/capacity cells to mitigate this.
LiFePO4 cells - they are actually quite capable for ebike propulsion, but their size/shape makes it very hard to customize shape unlike 18650/21700 cells.
Just started the video... I'm going to assume the increase of fires are from people not knowing how to modify their bikes with bigger batteries, quality parts, and not considering higher amps means you need thicker wires and higher volts increase the chances of a short.
When a battery is cold at touch, then I can reasonable deduct that there is no thermal-runaway running and/or imminent fire/explosion danger?
These chargers really should give an option to limit charge to say 80% state of charge (phones should too for that matter.)
Or, it's time box-in-the-middle gizmos are made that go between the charger and the battery which cease charging after a certain time, or amp hours, or voltage/current, or several of these measurements.
Manual timers make a lot of sense for a quick, cheap, easy and fairly effective insurance policy.
I live in a place where it gets down below 0⁰F so it's not safe to charge a battery out side. My idea in to charge the battery in a self cleaning oven. Of course not on the clean cycle or on. A self cleaning oven is designed to handle very high heat. Like a shut-off timer is a good idea too. If the battery catches fire the oven should be able to contain the fire at least until the fire department gets there. Fairly simple and no cost. A gas barbeque outside when above 32⁰F is another idea. The news locally of these e-fires is getting scary. Maybe some safety regulations are needed.
Nice presentation of useful information with a little comedy mixed in, I like it! New subscriber here.
Theseasonorg explains whole Bible God bless
First off, spend the money 💰 for a UL approved ebike, love my two Bosch juice bike’s 🚲
Lol " When my Wife got her new personality" i bloody roared laughing hahaha ,brilliant!
Another battery burns. Scary. We guys were talking about this today.
USING A I HOUR TIMER REALLY HELPS, AS I SIT ON MY COMPUTER I USE ME MY 1 HOUR TIMER IT GOES OFF ,I GO CHECK TO SEE IF THE RED LITE HAS TURNED GREEN IF NOT I LEAVE FOR ONE MORE HOUR. DEPENDS ON HOW FAR YOU WENT YOU MAY NEED THREE HOURS.
Like with almost all things, it takes multiple failures usually to have a bad day.
With ebikes, the batteries and the charger are the main issues. Cheapo batteries could be of poor construction and maybe not good BMS or even no BMS. If the battery pack is cheapo, you can bet the charger is cheapo too.
I agree using a large ammo box and/or a timer is a great idea. Those military surplus ammo boxes are made to handle explosions from inside and made to be durable and fireproof. As for a timer, you could use a simple mechanical plug timer or a "smart plug" or even go so far as setting up a way to measure the battery level and using it to determine when to shut off the power to the charger.
If you want as safe as possible (for your home at least), think about detached shed with power running to it and always keep the ebike and components in the shed and never in the home. That way, worse comes to worse, you lose a shed and an ebike but not your house and everything in it.
On a side note, lithium iron phosphate batteries are old school? Where have I been. I never heard of them until the last few years. They seem like a nice next progression overall for lithium ion batteries. Of course, we really need to find a way to have a safe batter with a high energy density that uses commonly available materials and not use lithium.
Great video! but I just want to stress that I don't think most people understand how much energy is stored in a typical E bike's battery. Take my add motor M81 it has if I use throttle only at least a 30 mile range it's an 80 pound bike and I weigh 200 pounds so just stop and think about how much energy we have stored in that battery think about the energy that you would have to expand pushing the pedals to bike 30 miles on an £80 bike if you weighed 200 pounds! Now imagine the equivalent energy stored in that battery because that's what you have should its short circuit catastrophically it could discharge some or all of that energy essentially at once so my recommendation is to never even think about leaving of charging Ebike unattended and whatever you do don't try to open up your battery pack and modify it or use a charger that didn't come with it unless you are a certified electronics technician familiar with charging and battery circuits. and again thank you for the great video
sometimes the reasons why it just because lock of knowledge in electrical and electronic " or wrong wiring undersize of wire and fuses can cause fire or not in Standards" or they can not use compatible charger to the battery" or they can not USE BMS ' sometimes overcharging but there is a Solution there's was a timer plug now that you can buy on the Shopping store " to prevent overcharging you can set the timer for how many hours you charge it and it will automatically turn off
I have a large fire blanket, and charge ONLY when I am home and awake….often when watching RUclips 😂
6:27 dont most batteries come with a bms which prevents over voltage, under voltage and also the battery charger itself detects that that the battery cells are 4.2v per cell so it should cut power to the battery. Usually chargers are indicated by an Led light which would tell whether your battery is charging or is fully charged.
Thanks for the reminder in over charging a battery. I made up a list of devices that I charge periodically and found it was 14! This includes to 2 ebikes, computers, walkie talkies, portable tire pumps etc. I use my cell phone timer to check hourly to see if the item is fully charged. Now with the ebikes I mostly charge the battery on the ebike in the "house". Why not in the garage, simple Answer live in Arizona where the garage temp is well over a 100 degrees which is not to compatible with charging. Question, do I need life insurance? Ebikes in the house is not a good for a match made in heaven. Or should I get rid of the complainer?
I just time my charge to check every 1/2 hr. then check Battery level... I don't wait for the green light and have no problems... I use my e-bike for local trips around town, maybe 5 miles... The Charger can get very HOT so I put it on top of a small white plate, glass dish...
as my luck has it, the charger went up in smoke within the first minute of charging today……
A charged Li batt has everything it needs for a fire. Unlike gasoline or diesel, cutting off its air won't stop the fire. Likelihood of a gire is different than severity of that fire.
My e bike battery not in use is stored in metal tool box with zip loc plastic bags of silica sand . The battery is charged to 80 or 90% on a luna charger on a timer . Next is store the battery in the shed in a cement fire board box .
This question has not come up here yet: What about the Lectric brand folding bikes, that keep the single battery INSIDE of a heavy steel tube? It can be charged inside the bike or out of it. How could it get enough air to burn if inside of all that steel? I charge with the battery out anyway, and keep it separate from the bike while parked inside. I would never leave a charging battery behind. Thanks for all of the good advice---I subbed!................................elsullo
How does a bullet get enough 'air' to burn inside of its brass casing? The answer is that gun powder and batteries produce the oxygen they need to burn via their chemistry which makes for a self sustaining fire due to them containing both fuel and oxidizer. Thermite is another product that produces a self sustaining fire.
i use similar cells for my ciggarette vapourizer, ive heard about them exploding in unregulated devices, fortunately my devices are regulated and no nasty acciedents.
I run 3 bats on my bike, run in parallel with a DX3 module. I never charge them on the bike. I always remove the bats to charge.
A lot if not a majority of e-bike batteries are made in such a way that there is significant pressure on the nickel conductors. Over time, vibrations can wear through insulators and..
I've never had a battery explode or catch fire during normal charging or use, in-part because I test and calibrate my charging equipment regularly, but also because I use quality BMS boards and I never use cheap e-bay / Aliexpress cells. I always go with a reputable wholesaler because that way I can confirm that the datasheets will be 100% accurate, the cells will be of good quality and that the only way to make them go boom is to force too much voltage in, or too much current out of the cells... Or stab them!!
I purchased a 52v 45amp battery that apparently uses Grade A LG Cells 21700.
They're called Conhis Motor. Do you by chance know if they're reputable or not?
@@Mash3OH3 I've not heard if that manufacturer... Best way to find out if they're truthful though is open the pack up and inspect the cells. Make sure the cell wrappers and labelling are correct and see if you can run a capacity check to ensure the real capacity is close to advertised.
While you're in there take a multimeter and measure each bank of cells and verify that they're well balanced and that your over voltage protection kicks in no later than 4.25v. Your cells should settle back to 4.2v when charged. If not, replace the BMS before use. I would recommend getting an ANT BMS since that will also give you live performance readouts and extremely detailed charge and discharge control over the pack.

Yeahhhhh I don't think I'll be opening it if I don't know what I'm doing lol.
I don't have an e-bike, but I'll take the humor all day long!
Its called Commonsense goes a long way and reading the Manual of your E-bike is a good thing to consider, like paying your Taxes on time.
I use a smart plug, then you can just use the app on your phone to set a time for the plug to shut off. That way it's not on all night. Some of these batteries can take up to 8 hours to charge.
Important video! THX!
Good explanations, good advice!
I've been riding an Ebike and charging ebike batteries since 2019, and I've never had a problem. Yes the charger I use gets hot when its charging, but its only a 2 amp hour charger. And when the battery is charged, the charger cools off, and I unplug it. I have left a battery charging over night, in my house, and it does not bother me. I think the biggest problem is people trying to fast charge the battery with the wrong charger. I've learned that if you slow charge your battery, it will last longer. Plus, I do not tinker with any of the controls. Just my two cents worth.
🤔 wrong charger?
@@StromLxrd6 Both ebike battery chargers I have are 2 amp hour chargers, yes slow but steady and I've never had a issue. The problem is most people are in a hurry, so they buy an after market charger that is maybe 4+ amps per hour and this is where you get into trouble. My two chargers get hot but not to a point of danger, when I use them to charge a battery. If I tried to use a 4 amp hour charger, I can only imagine just hot hot that would get. Plus I'm forcing a bigger charge into the battery then maybe its built in BMS, I think that's it, can handle, and thus BOOM. So there you go.
The battery on my Hitway from almost dead charges in 6 hours. I set a timer on my phone and unplug it as soon as l get a green light. The battery was room temp with only the charger slightly warm to the touch.
Too funny! What a personality! Thank you for the video.
Does getting a bike/battery that is UL2849 certified eliminate risks? I am retired on a fixed income and can only afford to do this once.
Mostly, yes.
All airplanes should have a steel case with fireproof mittens in them that they can throw a laptop or cell phone into in the event that it burns. Should be an international law. I use an ammo box and an old steel Milwaukee sawzall case at home for my batteries.
I just charge my Jetson Bolt in the Costco bathroom just in case.😂
I gave an old computer to a friend and he would leave it plugged in while wandering the internet. One day, at the Library, it finally had had enough and it smoked enough to set off the fire alarms. A guard knocked it out of his hands (he was trying to set it down) and rushed everyone out. An hour or two later, we came back in to find that it had eaten an impressive amount of carpet. We collected our stuff and they shut down for two days.
Thanks for the upload.
I bought a Luna charger and use to charge my e batteries to 80 or 90 % . Using a lamp timer on brick in case the battery is warm and only charging when
i’m home . I store the batteries in a metal tool box with find sand bags under and on top of the battery with smoke alarm . After charging I let the cells balance for a hour or more be use . I do this for peace of mind and What's Causing Ebikes Fires? precaution . I never seen any information on Lectric XP bike battery problems .
yeah I also have a Lectric XP 1.0, my only concern for you with all of the sand is it insulating the battery and causing it to heat up
Direct sunlight is very dangerous for anything which has lithium in a small case even more if you charge it simultaneously
The battery shown in the image that has a silver casing with black top and bottom is a battery Im trying to find .Any idea who makes it .I have one thats dead on my daymak bike and cant find a replacement . Its a 10 yr. old bike and nothing on their website.
up to yet i have not had a problem with my e-scooter battery ( that said i use my own charger so i can set the charge voltage and currant )
What about if the is outside 70,80,90, degree
0:38 That enough for me to subscribe 🤣
Excellent video. Thanks. Does your Mother-in-law know about this video?
I heard that charging them in a pressure cooker will stop any fire hazard?
This was a really good video. Thank you
Don't let your battery sit exposed to the sun for long periods. Don't charge it out in the sun.
Thanks mate for advice
Not one mention of impacting a battery. Breaking in a New Battery, or pushing a new battery to the max. most batteries have a proprietary charger that won't allow them to overcharge the battery.
