5:00 "in the end, it is always important to use protection..."
So true, so very true.
This happens if you don't use protection
4:54 not 5:00
Yup
If you don't, the battery get pregnant
@@DGMDevGamingAndMore 5:00 not 4:54
with a great power comes a great responsibility.
haha so tru
Thats a good one!!!
/holds up 20C rated monster sized lipo and stares at it/ I have so much power in my hands...
+Proyectos LED Hi Gastón, how are you doing?
+Proyectos LED Of course, that why Nokia's got too many battery blunders and Sony Ericsson got none untill the android arrived :)

Just a tip: ALWAYS unplug the battery plug, NEVER the charger connectors!
i cringed...
why
if you unplug on the charger side and the connectors come in contact you get sparks. and sparks are bad! just kidding, at 4:55 the dude does it. don't.
It won't drain much capacity but it'll probably melt the banana plugs. Did that, not once :)
think before acting!
Great video Scott. I'm an electronics engineer and I've only ever worked with UN approved professional Li-Po batteries which contain protection circuits. I was not aware that one could buy Li-Pos without protection circuits, so the dangers of these without suitable external protection in pocket sized equipment must not be underestimated. Thank you for sharing this.
Those batteries are mostly used for things like fpv drones and rc planes cars and boats, 1thats why you gotta have a special balance charger
Totally agree 👍🇮🇪
Very helpful information, nice work!
You watch GreatScott? I like your projects as well as his.

I have searched for a you tube channel for circuits and Arduino (I'm a huge fan of Arduino) .finally I got this channel. Great Scott teaches every thing practically.Ilove this channel
ElectroNoobs is a great channel for what you're looking for too. 👍🇮🇪
Remember: always use protection.
Lmfao
protection is number 1 priority
XD
+cyancoyote So stupid people won't be produces
Yeah, they totally won't be produces...
These must all be newer LiPO's. I had a Blade CX helicoptor and ripped one of the wires off the battery pack and while soldering a new one on I jumped the leads on the battery and it immediately puffed up and started billowing fire out of the side of it. I had to just let it burn because I couldn't blow out the flame. This was on my old coffee table which is now at the junk yard. These new cells look like they just blow off pressure and heat without the fire, that is pretty cool. But I don't think all cells are going to give this same result. Love the channel, subscribed.
Hey Barnacules
I feel like I find you in the comment section of every video I watch haha. Good videos btw, keep up the good work. That also goes for Scott :P
+Barnacules Nerdgasm trying to get some publicity i see
+введите бросок Somehow, I doubt that.
German quality you know :D
I love LiPo batteries for my RC aircraft, they're so light and have great capacity. As soon as LiPos became widely available I immediately started downsizing my internal combustion engine collection, converting many planes to electric. I've been using and abusing LiPo batteries for years and have damaged quite a few along the way, never once has one caught fire though. I still store them in a sealed metal ammo can and only charge them when I can be around to monitor it.
Good video! Very clear explanation, backed by simple and therefore instructional tests. Now I know the why some batteries puff and others don't and what I did to make them puff. (and to handle my batteries with more care in order to avoid things like short circuits etc.) Thanx!
Be careful of short-circuit when cutting battery wires ! 02:26
I did that back then and the 2 wires got burned.
its only for a moment, I don't think that the battery will explode or anything.
I was just about to comment this before I found this, this is an exceedingly common mistake to make and is part of why I'm going to need to replace my carpet in a few years lol
Such a short in a second or so will not lead to explosions

Hey, that was so satisfying to watch. Idk what you did in the edit. Maybe it was all the plugging and unplugging of connectors , desoldering and watching those batteries release. Lol
I just subbed brotha.
Good job man

You did this in the snow? What a hero!
To the point and informative as well as researched. Well done
Great video. a lot of good testing and information. I do have a follow-up video for you. you should slowly charge a battery until it overcharges and then explodes. This is what happened to me unintentionally and I almost burned my house down the kitchen counters all had to be replaced and the entire house was covered in soot. I walked in at just the right time and stopped the situation. The key to a fire is having something else around that the Heat and Battery can ignite. such as inside of an RC car or inside of a cardboard box. I really think you should test this as the result will be catastrophic and more aware for people who are not. nice work!!! ~Russ
When i saw LiPo, i immediately thought “Lithium-Polonium”. Then I thought: “that’s ought to be pretty dangerous indeed”.
me too
I love how you managed to include Hot GLue in an experiment about Overcharging batteries.
To me you're an electrical genius.
I liked and I subscribed. You have done the ultimate testing. Thank you
Keith Kuhn
One of simple tricks to prevent shorts is, if you have two uninsulated terminals or aligator clips or just plain stripped wires, is to cut one a bit shorter, so they are less likely to touch when they hang loose...
Or make a knot on one wire to shorten it, which is allso a good way to mark + or to mark pin 1 on ribbon cable or something similar (but you need to untie it if it needs to pass high frequencies).
You just gained a sub!
Thank you for amazing videos. I watch your channel almost all my spare time. Please make those coming more frequently if you have time on your hands.
+Ibreak Promo One video a week is all I can handle on my own.
Been using Lipos since the early 2000's. The first available for RC use(at least in the US) were the FMA/Kokam 1500mAh cells. Very expensive but a giant leap for electric powered RC. Still have some that will charge but are a ghost of them former self's, can't bring myself to toss them. Learned many lessons along the way. Never accidentally poke a cell while removing shrink wrap, never charge without a balancer as a fire can result burning down my shed(heres looking at you Astro 109 jumping cell count, I trusted that charger too much became complacent), and obviously never cut both discharge wires together. Lol! Still, best power source for high current apps.
Wow dude you are just awesome I just subscribed to your channnel ,congrats from Bulgaria

Excellent Video on an important subject!
(I would have like to have seen the same tests run on 18650 cells too!)
Thanks for sharing!
+zeffur7 I did similar test with 18650 cells a year ago. The video should be easy to find on my channel.
+GreatScott!
I just viewed it. Thanks!

Fatshark battery modification? If you don't know what I am talking about, just ignore it.
Wow,did not know they were that dangerous...Very useful.Thanks !🙏🏻
This is an awesome video man! Nice work thank you for sharing!
So did Anyone notice at 2:27 he shorted out the battery with wire cutters
Not intentionally
it's just momentarily. It is not as if when short circuited will act as a TIME BOMB...ready to explode LOL..typical non technical person.
@@MCircuits why time bomb? why not a regular bomb? there's no timer lol... typical non technical person.
Thanks for the interesting video. There is an information I haven’t found anywhere: does anybody know if a burned lipo battery looses significantly its weight? I have a setup that wouldn’t be disastrous if the batteries burn, but it would be a big problem if the CG gets shifted
great video and great scott :) as usually
so much knowledge!! nice vid man
Everything is dangerous if you throw it at the enough speed
+Jeronimo Murruni Good point
+Jeronimo Murruni Not to mention that you can always use it as a hammer...
+Jeronimo Murruni *Anything
Prajay Basu Not an english speaking person, thank you for helping me to improve :)
Jeronimo Murruni You're welcome ;) . BTW - I just read your comment again. The correct version should be "Anything can be dangerous if you throw it with enough speed" You're using "if", which means that you haven't thrown it yet - therefore you must use the work "can be" instead of "is". Also "enough" is not a proper noun, no need too add "the" before it.
@4:54 - Unplugging live banana plugs! Yikes!
+Joshua Bardwell Somestimes I am stupid
Joshua Bardwell I saw that too!
I thought the same!! I accidentally did that with my drone battery once... melted the plugs in 2 seconds. Do keep in mind that I was using a 6000mAh 6s 30C battery
Joshua Bardwell i
:D
Nice work!
You are great man.
I really love this type of technologies.
Lipo battery hardly try to become safe.
just to say, when unplugging lipos you should unplug the xt-60 first to prevent a short on the charging positive/negative 4:55
I don't know anything about this type of stuff. I don't know why it was in my recommendations. Still, it was interesting to watch.

+Tholaran97 your phone battery is similar and can explode/catch fire if over charged or if it over heats
Perhaps for the future. :)
maybe you dont know anything about anything. So why does it matter?

"The other batteries, DOOUUGH..."
I've always found this funny=P Great channel, Great Scott!
+GreatScott! you seem quite brilliant. I enjoyed this video.
Hoping you don't disconnect your batteries the way we can see in the video... Short circuit was 3 mm away ;)

Time for everybody to see this
Very informative video!Thank you!
Nice job you have a lot of good videos !
Erst den stecker des Akkus abzwicken, um so einen Kurzschluss zu verursachen, ok war ein kleiner akku. Aber dann den Großen 3 Zell-Akku beim Ladegerät so abstecken, dass die zwei 4mm Stecker sich berühren könnten?
The smoke from lithium polymer batteries is very nasty and could kill you if you inhaled enough of it
Nice
So can crack smoke
Anything can kill you if you inhale enough of it.
Mosaic Slime shit
I think it would require inhaling a LOT, as I've inhaled a decent bit and short of it smelling like complete ass, I had no lingering effects.
Excellent video.
Wow awesome video! Very informative thank you so much!
A new electronic component, the ballast transformer. 👍
I wonder what would happen if you constrained the battery's volume? IE: Made the pressure much higher? Would they get hotter? Act like a bomb? Just find a vent and steam a lot? I ask because phones are pretty solid these days!
+Jai Stanley I might try it out one day.
+Jai Stanley there wil be a lot of steam. You can make a rocket although from that :D
+Jai Stanley Yes if the pressure has no where to go it will eventually have to blow out someplace.
+DrScopeify No, the thin plastic shell of a removable battery is far too weak to prevent them from expanding; in fact, the best test to see if a battery is good or not is to try and spin it on a flat surface.
Not having to use the plastic shell around the battery is saving some space and volume that would otherwise be required, something that lets your gadget be lighter and thinner.
Thanks! Very helpful for makers!
Thanks for the info. I will use protection.
Most common electronics dont come with Lithium POLYMER batteries, they come with Lithium ION batteries. Lithium Polymer batteries provide more power but are less stable, but lithium ion batteries are stable like nickle metal hydride batteries while also producing a small amount of power for a very long time (in comparison).
+austin Milne They do. Just think of MP3 players, data loggers and everything small. There is no space for Li Ion batteries.
+xxpyroxx75 smart phones I suppose, there's your answer there. learn your amp draw during full use then check your amp hours or mah 1000 mah = 1 amp hour. there's a good reason buddy it's how much draw you put on the battery and the batteries capacity(amp hours) that determines how long it can go before recharging.
Ya, in comparison, the lithium ion batteries last forever
I literally opened the comments to type this but it looks like you beat me to it and you probably explained it better than I could have.
Wait but what about those battery cycles that wear off
Haven't you heard safety is number one priority!
lol ur a legend
Profile pic goes perfectly with comment
Crazy Russian Hacker.. lolz
Thank you, now i know more about my lipos:)
Very VERY informative!!
4:55 Funny thing waiting to happen!
4:55 Why did you do it that way? :p
Pretty good change to shortcircuit it like that.
You saw that too.. On a safety related video.
He was going to show exactly why you want a protection circuit ;)
Great video brother 👊👍🤘
Thanks for saying this important topic thanks a lot sir!
Please don't cut both battery leads together with a metal tool like at 2:26
+Jeremy Lee It was the cell with the protection circuit. I had nothing to fear.
+Jeremy Lee I cut a few li-po batteries in half with metal scisors and as you can see, I'm still alive (nothing happened, not even fire).
+Jeremy Lee A short burst of high current that would be rare when doing that won't damage the battery xD Additionally, at only ~4v... it will pass through the cutters without you even noticing...
+Евгений Мельман The short circuit happens in under 1 second, so it's fine
+OH MY GOD!!! The risk you haven't considered is welding the leads to the cutters and therefore shorting out the cell for much longer. Spot welding only takes a moment, and the energy density of LiPo cells make spot welding a possibility.
it's like the note 7

The note 7 actually explodes and there is an intense burn and flames
great Scott!!!
Very informative thanks for posting
Resume: If there's a little PCB in you baterry its fine.
What I learned: always use protection
Very well done, thanks
thanks alot, this answers my questions on lipo batteries
Lithium batteries are great and all, but guess which battery you use when you want to abuse something and not have that battery catching fire? Lead-acid batteries are heavy as hell, but they're so forgiving.
+MrJohhhnnnyyy careful about the hydroxy gas tho
I don't think you have to worry about that if you have the batteries with gel type electrolyte, aka sla, or Vrla.
DMAN22yeah I'm aware of that, but it's not a huge issue.
MrJohhhnnnyyy yeah, just dont spark near it under high load
Even more forgiving is a Ni-Fe cell, which uses KOH/NaOH dissolved in water for electrolyte.
The worst that happens is you need to top off the electrolyte. These kind of batteries can last a lifetime.
There are reasons both Lead Acid and Ni-Fe are still commonly used. Durability and cost. :D
I'm not gonna lie, at 5:01 when it sparked I jumped.
Ron Tropics 5:00
Me too 😂😂😂😂😂😂😂😂😂
thanks dude I like all your video
Finally, someone who actually shows what happens!
drone peeps where ya at
wouldn any type of battery be dangerous when overcharged,overdischarged or short circuited?
Sure, but some are more dangerous than others
lol, did i just saw greatscott replied a 10 months old video? i was like wtf.
anything excessive is dangerous...Bear that in mind!
puffed up very nicely :D
You are a 'REAL GENIUS'
420 volts :)

Oh yeah lets act like teenagers and talk about marijuana. Fucking pathetic
it was actually 4.20 volts
Lol... First I read: "How dangerous is the life of a go pro?"
Think you need some sleep
I clicked because "how dangerous are lithium-polonium batteries?" I didn't think that was right, and if it was, I needed to know what applications such a battery would have.
@@awfuldynne it's polymer
you are awesome your videos are best in the fucing world i subscribed
If my device has protection chips on it (8205 & XB8777A), are there any issues with using a battery that has them as well? Will they conflict with each other?
what's the name of the tape you pulled off?
kapton tape
David tape.
mixtape
I have so much of that leftover from my original Makerbot
Saw this vid and thought yeah of course a Lithium Polonium battery would be dangerous. Joke is on me though.
Thx for your helpfully videos :D
Had a thermonuclear moment with a battery today, tried to salvage a cell from an old pair of wireless headphones and may have crushed it a bit too hard while freeing it up. Definitely exciting when the cell gets rid of all of it's charge within a matter of seconds
For future reference if anyone wants to make an old cell safe for disposal, I recommend putting a resistor in between the terminals (bypassing the protection PCB) so that it will slowly discharge all the way to 0V, otherwise the protection will stop it at around 3 Volts. Once it's really close to 0V you can just tie the 2 terminals together and throw it out and it has no chance of blowing up anymore. Generally speaking a 100 ohm resistor should be pretty good for most batteries that are near the 4V range, as the voltage drops down you can add another one in parallel which drops the resistance down to half (50ohm) and then it wont take all day. This whole process should be done near a sink or other area where it wont burn anything down in case things do go wrong when you're messing with it.
Blowing one up definitely makes them inert but the resistor method is a lot less messy and keeps the battery sealed
"It is always important to use protection"
Also everything is dangerous if you're stupid enough
damm i came to see explosions
