Dangerous vs. Safe batteries, Explosion and fire test!
Li-Pol (LiPo) batteries are widely used in nearly all Cell phones and other home electronics. Yet, they are unstable and dangerous. In our test, we compare LiPo with available LFP and LTO technologies.
You may not recognize the danger of sitting in your pocket, but consider the danger for projects involving batteries and prevent future issues. Designing a machine, device or tool that uses batteries? Choose wisely!
All tested batteries are based on lithium, however, the additional substances in LFP and LTO provide necessary stabilization and prevent dangerous behaviour.
Are you wondering how toxic is that smoke? This we've measured in this episode: • How toxic are the Lith...

Weird @6:17. I have never seen a LiPo in an 18650 Li ion package before. Where did you get these?
Wow ...
@@headlessxp4948 lipol is a battery brand. Lipo is a battery chemistry type. The video is a bit confusing
kzhead.info/sun/edqkmd2Oi6iegIE/bejne.html those Winstone batteries sucks big time
I hope you cleaned all this contaminated site after your tests. I can see the crop fields near by. Do you know that lithium batteries are very toxic, especially when burning. You even spilled some water on punctured cells, which then ended up in the soil. The worst thing is that it was done by firefighters, as usually they are the persons who knows about such dangers. But not in this case, it seems they are stupid enough even to breath in the toxic fumes.
conclusion : lipo batteries are a good substitute to firecrackers
And life po4 is a great toxic smoke bomb substitute
Conclusion: GWL is a no good company that is taking our rights to own batteries that can spontaneously combust
For me, it's a source for death smoke, and oh, the smell of fire
@@CarLoverPhotography naaa ,not enough smoke
The thing you are holding is also a firecrackers
I knicked a lithium pouch with a box cutter in my bedroom :) I ran with it in my hand to the other end of the house to find the screen door locked! Grabbed the keys and unlocked the door, I threw the battery which was a massive smoke machine by then, before it hit the ground it burst into flames ! That was a close call ! Lesson learnt !
lol when you cut that lithium pouch : "the bomb has been planted"
Wow. Close call for sure. Hope your hand was alright!
I'm just genuinely curious... you're screen door has a key lock on it? And why is the lock on the wrong side? Lmao
@@huntzkush LOL
That screen door is almost certainly a fire code violation. A point of egress must not lock to the inside without a readily available means of unlocking it.
So,regardless of battery and application (other than cars) it looks like it would be a good idea that the battery box should be something like a wood stove /oil drum stove with a chimney that vents to the outside for solar and wind battery banks just for precautionary safety... This video just made me redesign my bank in my head over a power wall
I actually put my ebike battery inside the stove when I charge it.
Tesla always shows their power wall bank things outside the house in all their images for this reason
Maybe all EV batteries should have a fireproof chimney. Just in case.
we make battery bunkers for charging lipo batteries in the FPV RC drone hobby. its a fireproof brick stove, with a battery charger inside... our 6s 1500mah batteries could burn a house to the ground.
safety and energy density is always a engineering tradeoff. most of the more volatile chemistries are perfectly safe if treated right. but there is something to be said about using inherently safer chemistries for alot of applications.
Exactly. Li-PoL are very common because of their form factor compared to that of the others. You may say that they're super dangerous, but that's if you're excluding modern circuitry that commonly comes with said batteries effectively eliminating almost all of the risks. Similar way to Nuclear Power in a way. It is arguably one of the cleanest and most efficient energy production methods. Modern plants have many safety features making a meltdown very very unlikely. But due to it being also one of the most horrible disasters if it does go horribly wrong, a few accidents have put a bad taste in many people's mouths.
@Stratos Fear Nuclear power is safe if you follow proper guidelines too :) Jokes aside, nuclear power is the most efficient source of energy right now and also one of the cleanest at the same time. Sure there is nuclear waste, but there are reactors in development that can use said waste as fuel. The most used power plants are still coal ones and they are much worse ecologically than the nuclear ones. Not even mentioning that by burning coal, there are radioactive particles released into the air.
@Stratos Fear how about Hanford?
@@BloPsy__ So why does everyone wanna get rid of nuclear power and cover everything in PV panels?
@@mode3763 Because of the "very smart" people that fear the Nuclear energy. Germany is great example. They had shut down their nuclear power plants, yet their renewable energy sources aren't sufficient enough for the country. They are buying energy from other countries - that energy is mostly produced by coal and nuclear power plants. For example, Czechia is the one country that is selling it's energy to Germany. And Czechs do not want to shut down their nuclear power plants even tho there are a lot of protests from their neighbours. They even plan on upgrading the existing powerplants to get more energy, because they know that coal will once dry up and nuclear is only viable option in this part of the world. Solar panels are utopian dream that will cost huge amount of money and will pollute our planet a lot if everyone will really switch to that. Not even mentioning the need of some sort of energy storage for winters, bad weather times etc. It will be probably huge battery banks, which will only last for few decades since you know, batteries, that will pollute our world so much, that those "very smart" people will regret not trusting Nuclear energy.
Interesting tests! What was the state of charge of the batteries? Note that the probability of a thermal runaway significantly drops at a low state of charge. This is especially important when buying cells that have been transported by air. Those are usually shipped at 30% SoC.
I wish it would give the statistics such as the voltage and amperage when it was overcharging at the time.
I recommend these videos to my readers who say lifepo4 is a bad chemistry. Great video!
What's their casw against it?
@@chrisE815they are extremely sensitive to cold temperatures, but that’s about the only major issue with it
Lifepo is cold resistant actually, their drawback is lesser energy density afaik @@chrisE815
Li-Pol Is like “You have chosen death” 😡 ☠️
LiPol are mostly used in RC devices like planes and cars where performance is the most important (energy density and power density) safety is not a high priority in this application.
Cell phones
Those are interesting cases .. but .. what was the overcharging current for each case .. cause it really depend on the charge current.
Many thanks for doing the first fair tests I've seen anyone do.
This was very well done, informative and interesting to watch!
great job guys...appreciate your effort
2:39 whenever my dad sneezes
😻😻😹😹😹
great demo video, thank you!
Thanks for the video👍 Well I would have liked to see the voltage, current and Wh and the cell should have been at the same ah. As you see some people seam to be confused and believe that the "safe" cell has the same energy density. The first thing to understand wit battery is that there is a trade off no matter what you do.
Good points. LTO have less than half the Wattage-density and are lower voltage too. They also have a more stable voltage loss during discharge, which is great for output usage but makes measuring their charge percentage less accurate.
@@JasonJrake Uh... LTO has a higher cell voltage than LFP. It does have lower Watt (VoltAmp) density. Will Prowse has a nice comparison of LFP to LTO here: kzhead.info/sun/nLN7g9x9qIqLhJs/bejne.html
@@kayzinti4452 I’ve seen that video and I’m not sure what you are referring to. The lowest listed nominal ratings i found online: for LTO is 2.4v, for LFP it’s 3.2v. Maybe cells arranged into 12+ volt stacks are higher voltage in LTO though, if that’s what you mean. The rule of thumb for lithium chemistries is that: As nominal voltage goes down, Discharge voltage slope flattens, Functional Temp range increases, Watt-hour density decreases, Safety increases.
batteries be like: LTO: i squirt LiFePO4: i swell, i smoke LiPo: i boom
Spilling highly toxic waste next to crop fields... Breathing in highly toxic fumes... Best firefighters I seen so far...
Спасибо за тест! У меня много li-ion и li-pol аккумуляторов, теперь знаю как ведут себя в разных условиях.
Great video guys, thanks
An interesting & very practical demonstration of the various battery types, thanks for posting.
This is why you need to use fuses and charging regulators for all types of batteries. This is a wonderful wonderful test.🤗🤗
Nope this is just a marketing scheme to show lipo as a ticking time bomb
👏👏👏👏👏 Thank all of you for this training video.
Does the transition metal ions present in the cathodes (other than LFP) influences or catalyzes the thermal runaway while damaging. in both cases, Li-ion shuttles and the same carbonate electrolyte. (in electrochemistry point of view completely agreed, but..), pls clarify my doubt
I've been telling people for years about the dangers of making a battery bank with Lipo batteries and those people looked at me like I was crazy. While LIFePo4 batteries will combust also. The chances of having an unpleasant reaction inside a structure is greatly reduced especially with a battery management system that can monitor the temperature and the individual charge on each battery in an array. The cases that house the electrolyte for LIFePo4 batteries are pretty resilient against physical damage. They are unlikely to be damaged unless someone uses a tomahawk like in the video or uses a wrench and physically short circuits the cells through stupidity. Remember a fuse is your friend, always use one of the correct rating. A breaker may not be so friendly.
ur crazy
@@UREALERO Jealous.
huh ? isnt lipo use for RC only ? battery bank is li- ion
@@sdqsdq6274 Nope,li-ion means it have liquid electrolyte,li-po have solid electrolyte.There are LFP batteries that can be li-po a the same time
Even with LiFePo4, I'd want my solar farm's batteries to be in a concrete box, away from any combustible structures.
4:34 dude you've just released the demons imprisoned in that battery. You're now curse by that battery's evil spirit.
Everyone should know about the occult and the evil in this world. And batteries are the main source. They're not allowed in hell because they're far too evil for hell that's why we have them here. Repent.
Great study!
best education, very useful information, thank you.
Never heard of LTO. Thanks!
Been around for many years, but you don't find them in consumer products because normal li-ion cells have much higher energy density. Apparently, LTO cells are best used in orbital satellites, where they have to endure many thousands of charge-discharge cycles and have an extremely long calendar life.
LTO isn't very common due being rather large & expensive compared to other chemistries. But it's by far one of the safest and most reliable chemistries out there.
Imagine the smell...
Thanks for good information
Very useful video,thank you for knowledge able video.
Unsafest fireman i ever seen with electronics. Suprised none of them for the exception of one wore a mask because Lithium batteries burning is highly toxic!
Yeah. Breathing smoke and vapors from something burning is one of the fastest ways to get poisoned. I was surprised at how few who were standing so close had no face protection.
Thats why outdoors and probably upstream of wind. Fire protection was enough, however eyewear is a must
I agree. More - This type of test is manipulated because LiFePO4 Cells will burn and blow up, too - if they are fully or overcharged! The smoke is burnable to! With this video you "fake" Security. This video is cut very forward to sell products.
@@ElectrifiedStud most definitely a battery lead flying in the eye is most un cool.
@@jasonpotter4880 kind of like the DDT add from the 50s with a girl eating a hamburger while they sprayed DDT on her to prove how safe it is. She died rest her soul.
Would have been nice to actually hear the batteries exploding.
Highly impressive information!
Excellent real world test
Overcharging circuitry is critical with those pouches. It's also necessary to seal properly; never pinch them on the top edge (or anywhere) like Samsung did with Galaxy Note 7.
samsung note 7 have bad batteries not bad construction. learn and stop talking shit
LiFePO4 cells seems to be safe enough to replace the Li-ION cells inside my power bank. The hard part is to design a new charge controller PCB that fits the same space as the current one.
And find some LiFePo4 cells small enough to fit in a power bank while still providing a useful capacity
@Murphy deffa or lose half again and opt for LTO lol, thats what im doing, cause id rather have to lug around a huge battery than worry about my 200wh+ behemoth bursting into flames or a cloud of lethal smoke if something out of my control happened. cell level fusing and smart BMSs with extra failsafes are great and all but if something happens out of your control that bypasses those, some total black swan event you could never have seen coming, i dont know man but to me it seems worth it even if my phone will feel like carryign around a VHS tape...
@@doooofus i think it'll be bigger and heavier than a vhs tape. Just carry around a hand crank charger if you're so worried about your powerbank exploding. 🗿
@@aivarsaar Well you can do a away with a lot of cooling and make prismatic cells, gaining back about 20% of the capacity. Also they lose capacity slower, so after 5-6 years it will start closer together. On top of that, you can use then with both more and less charge, doing 0-100% instead of 20-85% in daily driving, while true, on long drives, the range will be shorter
Hello one question. There is a cylindrical cell of about 10 to 15ah so it can be installed in a electric motorcycle
Thanks for making this video
I'm sorry, but nowhere in this video is the voltage of each battery type measured, so how do we know if the LTO was even charged at all?
Thank you the best comparison I have seen.
Epic Loved it, those lipo batteries are mental lol
Do you have an idea what is the short circuit current of the Lfp cell ?
So basically Li-Pol a smoke grenade...
Great video. Feedback: The experiments were conducted without a safety barrier. Your specialists were exposed to danger during the experiment. The specialist is invaluable even if his experience is little. Your beautiful experiences benefited us.
While the test could be made safer, absolutely. With all honesty, this wasn't our first experience with any of the showcased technology during similar critical situations. It was first where we filmed the results in somewhat representative manner. Still, next test videos will be improved primarily to educate everyone else, on the danger level during such testing. For example, it is why we have chosen very tiny LiPo based cells (18650 form on the video during the external fire test), because larger cells would be serious danger to the personel.
@@GWLPowered RESCUE THANKS 🙏
What kind of camera do you use in 0:50 which is resistant to high temperature?
hello bro can i use this video contend for my you tube channel for education purpose
Definitely building an LTO bank for my new audio build. Wanted information on the safety of lipo and LiFePo4.
LTO cells are supposed to be good for an enormous number of cycles and have an extremely long calendar life. The have lower energy density (store less energy for their size & weight) than either conventional li-ion or LiFeP04 cells.
That overcharge LiPo battery just turned into Saturn V rocket exhaust
More like half of a satellite's RCS thruster, but still a rocket.
Thank you I know this video only possible a lot of time of you and hard work Thank you again
This was the best Lipos Batteries test I have seem 😃😃😃👏👏👏👏👏👏
The LTO cell looks like a SUPERCAPACITOR 💪
It's packaged with screw terminals due to the high current rating for LTO batteries.

Is lto better than lifepo4 on capacity per cell?
hi, very interesting what voltage was used for overcharge
Why though
Just increase the ampere.
@@kiranranjitkar2748 That’s not how it works.
Can get overcharge fire at about 5.2V/ LiPo cell, maybe less. Guess how I figured that....
It is not li po it is li ion battery
Thank you very much for the battery testing comparison. Now I can sleep in peace!... Is GWL available in Canada??
We are based in Czech (EU), we do ship to Canada.
Thats a great question but wtf this question is so dumb

Thanx somuch 4 education 🔥🔥🔥👍👍👍
TIP÷ Li-pol(lithium polymer)batteries are used in most phones and has a limited heat capacity.
Conlusion : LifePo4 is safe if it is stored in a safety canister.
This music is incredibly ominous and thinking of many scenarios that it would fit perfectly in
Klasse Vergleich
Kudos to the bravery of the guy who axed the Li-Pol and stayed there holding the axe!
Try that with the battery in my old merc, took days to charge
:()
Sad how much amp hours?
Good Advertisement. Salute to the Team who Risk their life to prove the safety of their products to the Customer.
Your information is useful
What is the voltage supplied to each batteries when overcharging? The test should have been done with same package type of batteries and not different from one and other.
Really interesting to see that there is no safety discipline around such experiences (except for firefighters)! At a minimum, protective glasses for everyone.
Yea. They’re wearing protective clothes, but most way to close with no eye protection. Better off wearing tee shirts and safety glasses
good job
LiPo batteries always remind me of microwave popcorn when they fail. 🔥💥
This is like ASMR lol
:D oookay, we might be missing some audience targeting then! :DDD
Nice video, however to be fair, what you tested at 6:19 was in fact Lithium-ion and not Lithium-polymer
i guess they are similar
@@tablet4170 nope.
LiPo are also available in round cells, so it is probably what they claimed. You cannot judge that by looking at the video.
How can you tell ..? LiPo exist in cylindrical package ...
It is the same technology on a different package. Both are based on the LiCoO2 chemistry. As an aside, the "Li-ion" designation covers many chemistries, including LiFePO4, but generically refers to the LiCoO2 chemistry.
Buen video .las pilas si estan a 2.5v .oh 3.0v se pueden espezar s conectar a cargar i aser la la bateria k kieres aser???
thanks
1st Grade LTO and 2nd grade LFP ,, no more polymer safety point :(
For all those asking what the numbers were. Don't over charge, over discharge, or short any battery. Doesn't matter what the numbers were.
I respectfully disagree. They should have included that data b/c it's interesting & germane to the overall discussion of safety & performance tradeoffs between various battery chemistries
Hallo. Explodieren Batterie nur wegen mechanischen Schaden und Überladung? Mein Akku 36V 10S (20 Batterie Li-Ion) ist beim Laden sehr heiß, drinnen gibt es BMS, trotzdem lässt sich das ohne Stop laden, und nach 5 Stunden Laden hat der Akku Spannung 42 V. Ist das ok? Wenn ich ein Stahl Box für Akku bastele, reduziert das Schaden wenn ein Explosion passieren soll? Danke!
hello mr, may i download the video and then upload it on my youtube channel...?
I've been looking into battery options for van building, and considered installing LTO 40ah batteries running parallel at 48volts. I then saw a video of Li-Pol batteries exploding after it was punctured and thought "fuck that i'm not gonna drive around as a mobile time bomb", but I'm glad I got to see this video and now know if it overheats/gets damaged there are self contained precautionary measures.
I'm using lto in my scooter and I'll never go back to 18650 li ion. The cells are so strong you can even charge and discharge them at high current and they will still last decades.
why can i smell the battery smoke through my screen and why is it giving me a headache lol
LiPol: it’s either explode or explode Take it or leave it
What's the music during the first 2 minutes? It's really powerful!
Interesting in what chemestry the lipo was? And also want to know cell voltage/temerature and c rate during charging.
Lithium polymer. They bypassed the safety circuit on the lipo and also the charger. If you use a proper charger it's very safe. Most normal chargers won't be able to do the c rating a lipo will need to go up in flames. My charger is rated at 5amp I can charge a lipo at 5c. I do charge my xpower batteries at 2c no problem
Under a normal battery charging process...I think most people would be using a smart battery charger, volt meter, temp probe, circuit breaker or fuse to prevent a fire or over charging situation.
Temperature probes, circuit breakers or fuses are not suitable to prevent over changing (charging above the design voltage). They are only suitable to prevent damage from high charging current. Without cell balancing even regulating the charging voltage does not protect from over charging.
Nice test
Very interesting experiment
Odd looking lipo for the ignition test looked a lot more like a lithium ion 18650 than a lipo
And how exactly will I get my Quad up into the air with those "safe" batteries?
they are almost as powerfull
I think they're aiming this advertising campaign at the industrial market and energy sector.
@@MatthewSlaymaker true....but then why compare to Lipo aka pouch cells?
