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 :)
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?"
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 ..
Well you’re gonna have to give your phone then, because the battery in it could spontaneously combust too. And your laptop if you have one. And any tablets.
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.
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.
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. ;-)
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.
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.
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.
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.
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 ✔️
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!!!!!
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..
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
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.
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.
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!
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.
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
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.
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 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.
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.
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 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.
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.
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.
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.
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
The battery for my wearable vest swelled enough to fracture the case. I removed/examined the battery & was not comfortable with continuing using it. Replaced with two (used) cells from a laptop battery. How smart am I . . . . . . . . errrrrrrrr . . . . . . . . it works well, keeping me warm as I type this . . . . BUT, as you suggest, I am afraid of an overcharge possibility & therefore pay attention when recharging this or any other li-ion battery. LiFePo4 batteries am not so worried about . . . . . . . . thanks, RH
I have a VIVI Folding E Bike mountain bike the battery 🔋 goes in front of the handle bars I always check the battery 🔋 when charging it if it seems to get warm I unplug it
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.
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 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.
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?
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.
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.
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.
5:10 that assumes a linear charge curve. In reality lithium batteries charging is closer to (though not exactly) a logarithmic curve, with the peak current only used at the start, gradually dropping off as it gets closer to 100%.
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 .
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.
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.
I did buy & use a battery fireproof bag from Amazon. I take my battery off of my bike & charge it in the bag. I'm always present when it's charging & keep an eye on it & disconnect it when it's charged. I don't charge it overnight. So, the bag I use is of no use if the battery overheats? It won't contain it if the battery overheats? Is that what you're saying?
I guess by now everyone has seen the video of the guy that carried his eBike battery into the elevator. The worst happened just after the doors closed. Almost instantly you couldn't see anything from the elevator camera. The guy died in the hospital a few days later, I believe it was. It was actually a huge battery, like maybe it came off a street legal motorcycle, or something. It looked like maybe the elevator was in a parking garage below an apartment building. The elevator, I'm assuming, went to the guy's floor, opened for a few seconds, while he was probably already unconscious, and then a camera in the basement showed people waiting for the elevator. When it opened they jumped back, obviously shocked by what they saw. I'm sure it was a sight they'll never forget.
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 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.
My Json Pro is dead, after 180 hours of use (2 years). I am not sure if the problem is the charger, power plug, or battery. I will start troubleshooting with the charger. Wish me luck.
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.
do i have to worry about a battery on my ebike thats charged and off the bike but has not been used in a week, can they just catch on fire on there own sitting there?
No, I wouldnt keep it in the house. I wouldnt even leave an EV in an integral garage. Park it on the drive. Get a mouse or other rodent nawing through a cable and causing a short circuit and it could end up with a battery fire.
@1701_FyldeFlyer I usually charge it on the patio. It stays in my room at night. I don't have the money if it's stolen. Electric bikes are considered bicycles in N Arizona towns. Sidewalk, street, dirt trails the cops could care less. I just want a Sur Ron someday. My truck has sat since 2010 in the open, rats never ate anything. I know another part of Arizona the rats kept eating the wires everyday on my sisters tractor. It depends on where you are.
@@Mark-qv4bn I keep mine inside too, if I had a surefire safe place to leave it outside then I would, but as you said they are too expensive to take risks with. I charge mine in room after use, I am always around when it's charging then it sits there until I use it again.
They do, however, the issue is That many ebike chargers have not been UL listed have not been tested, and can falter. On top of that, many folks have multiple Ebikes. Often times, 36 volt and 48 volt chargers use the exact same fitting. It’s easy to mix them up and create a small disaster.
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 .
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.
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.
I've had a e bike for 8 years

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.
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 ..
Well you’re gonna have to give your phone then, because the battery in it could spontaneously combust too. And your laptop if you have one. And any tablets.
@AWriterWandering your an idot
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.
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.
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. ;-)
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
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.
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.
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."
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.
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.
You present information in an easy way to understand and in a easy relaxed manner. Thank you…
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!!!!!
@@rickevans3959 you cant short a electric scooter battery by droping something on it bc there are no terminals
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.
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
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.
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.
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!
bro i dont even have a battery but the sound effects kept me watching the whole thing lmao keep it up
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
like your video when you said use a timer cut out i have 2 timers have a nice day colin uk
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.
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
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.
Belt and Braces use a timer. 2 hrs on 15 mins off etc. It helps.
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.
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..
*"it's just better policy to avoid the plane catching on fire"* 🤣 Words to live my friend... words to live by.
Your a brave man to talk about your wife's personality 😮
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.
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.
@@HobbyOrganist I guess you are right, Mr. Organist
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.
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 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?

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.
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.
Is there a chance for a battery to catch a fire if not plugged to charge?
Is it safe to leave it on the bicycle with the switch turned to off ?
HAHAHAHAHA "like eating too much Taco Bell" the deadpan delivery on this channel is great.
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?
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.
The UL certification means a battery has met certain safety standards, including resistance to overcharging and overheating.
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 have a VIVI Folding E Bike mountain bike the battery 🔋 goes in front of the handle bars I always check the battery 🔋 when charging it if it seems to get warm I unplug it
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.
First off, spend the money 💰 for a UL approved ebike, love my two Bosch juice bike’s 🚲
In joyed the video 📸📷 now I now what kind of Bratre to get for my 🚲🚳 ebike
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.
Thank you for the battery info and the stand-up comedy AAAAA
Too funny! What a personality! Thank you for the video.
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.
What about if the is outside 70,80,90, degree
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?
You can get an auto timer to turn off the charger. Simple fix and you can set for multiple time lengths.
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.
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.
Another battery burns. Scary. We guys were talking about this today.
I have a large fire blanket, and charge ONLY when I am home and awake….often when watching RUclips 😂
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 heard that charging them in a pressure cooker will stop any fire hazard?
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.
5:10 that assumes a linear charge curve. In reality lithium batteries charging is closer to (though not exactly) a logarithmic curve, with the peak current only used at the start, gradually dropping off as it gets closer to 100%.
Good explanations, good advice!
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

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.
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.
How long will a fully charged battery hold its charge
Excellent video. Thanks. Does your Mother-in-law know about this video?
I did buy & use a battery fireproof bag from Amazon. I take my battery off of my bike & charge it in the bag. I'm always present when it's charging & keep an eye on it & disconnect it when it's charged. I don't charge it overnight. So, the bag I use is of no use if the battery overheats? It won't contain it if the battery overheats? Is that what you're saying?
I guess by now everyone has seen the video of the guy that carried his eBike battery into the elevator. The worst happened just after the doors closed. Almost instantly you couldn't see anything from the elevator camera. The guy died in the hospital a few days later, I believe it was. It was actually a huge battery, like maybe it came off a street legal motorcycle, or something. It looked like maybe the elevator was in a parking garage below an apartment building. The elevator, I'm assuming, went to the guy's floor, opened for a few seconds, while he was probably already unconscious, and then a camera in the basement showed people waiting for the elevator. When it opened they jumped back, obviously shocked by what they saw. I'm sure it was a sight they'll never forget.
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 😅
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 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 don't have an e-bike, but I'll take the humor all day long!
Lol " When my Wife got her new personality" i bloody roared laughing hahaha ,brilliant!
Are in fram batteries a better option?
My Json Pro is dead, after 180 hours of use (2 years). I am not sure if the problem is the charger, power plug, or battery. I will start troubleshooting with the charger. Wish me luck.
check for loose connection
This dude is truly great n funny top advice too 😅
Glad you enjoyed
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.
This was a really good video. Thank you
Are 100% of these thermal runaways during charging? Do they ever occur during discharge, while In use?
do i have to worry about a battery on my ebike thats charged and off the bike but has not been used in a week, can they just catch on fire on there own sitting there?
keep out of the sun or high heat, and it'll be fine :)
Is my ebike safe to keep inside the house? I've been keeping it inside for over two years.
I have for over a year. No worries.
No, I wouldnt keep it in the house. I wouldnt even leave an EV in an integral garage. Park it on the drive. Get a mouse or other rodent nawing through a cable and causing a short circuit and it could end up with a battery fire.
@@1701_FyldeFlyer thanks for the information 👍
@1701_FyldeFlyer I usually charge it on the patio. It stays in my room at night. I don't have the money if it's stolen. Electric bikes are considered bicycles in N Arizona towns. Sidewalk, street, dirt trails the cops could care less. I just want a Sur Ron someday. My truck has sat since 2010 in the open, rats never ate anything. I know another part of Arizona the rats kept eating the wires everyday on my sisters tractor. It depends on where you are.
@@Mark-qv4bn I keep mine inside too, if I had a surefire safe place to leave it outside then I would, but as you said they are too expensive to take risks with. I charge mine in room after use, I am always around when it's charging then it sits there until I use it again.
Subbed because I like your sense of humor lolol. Starting with the wife /new personality comment. Bahahaha. Lipos scare me btw.
I thought batteries in modern devices automatically stop charging when they are fully loaded.
They do, however, the issue is That many ebike chargers have not been UL listed have not been tested, and can falter. On top of that, many folks have multiple Ebikes. Often times, 36 volt and 48 volt chargers use the exact same fitting. It’s easy to mix them up and create a small disaster.
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 .
I have a Ryobi cordless weedeater. Sometimes when I just Finnish using it and then plug it in, it gets really warm. I am very careful
Theseasonorg explains whole Bible God bless
a timer was the first thing I bought. although my charger stops charging when the battery is full.
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.
I have an Aventon e-bike and never had any issues with charging the battery on it.
I have kugoo kirin b2 400w a similar bike like yours Jetson bolt. You know what diameter battery can fit inside the bike;
the max width/thickness is 2.8". if the kugoo is 48v 7.5 or 36v 10, then you cant go bigger without some cutting.
I also am fortunate enough to have a KK-B2 (I call it "The Nipper') - great piece of kit. Enjoy the moment. "Have helmet - will travel".
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.
