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 Lithium batteries a...
We tested:
Overcharge
Li-Pol (0:24)
LTO (1:03)
LFP (1:28)
Short-Circuit
LTO (2:27)
LFP (3:02)
Puncture
LTO (3:54)
Li-Pol (4:28)
LFP (5:05)
External fire (ignition)
Li-Pol (6:17)
LTO (6:30)
LFP (6:56)

conclusion : lipo batteries are a good substitute to 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 !

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.
-
Li-Pol Is like “You have chosen death” 😡 ☠️
-
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 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!
-
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.
-
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.

Spilling highly toxic waste next to crop fields... Breathing in highly toxic fumes... Best firefighters I seen so far...
-
This is why you need to use fuses and charging regulators for all types of batteries. This is a wonderful wonderful test.🤗🤗

2:39 whenever my dad sneezes
-
Those are interesting cases .. but .. what was the overcharging current for each case .. cause it really depend on the charge current.
-
This was very well done, informative and interesting to watch!
-
Спасибо за тест! У меня много li-ion и li-pol аккумуляторов, теперь знаю как ведут себя в разных условиях.
-
4:34 dude you've just released the demons imprisoned in that battery. You're now curse by that battery's evil spirit.
-
Many thanks for doing the first fair tests I've seen anyone do.
-
LiPo batteries always remind me of microwave popcorn when they fail. 🔥💥
-
batteries be like: LTO: i squirt LiFePO4: i swell, i smoke LiPo: i boom
