@@psirvent8 No no, the smoke CAN kill you. It would have to be radioactive to be more toxic. Thankfully a properly made battery pack stops the whole pack from turning in to a 5000 degree pile of molten slag, incinerating everything within a meter or two of it.
We just built our own battery bank on our sailboat (we liveaboard) using 180 amp hour, 3.6-volt CALB cells, and a DALY BMS, wiring the cells in a 4s2p orientation. So stoked on the upgrade! We charge our lithiums in 2 different ways. We send the power from our 120 amp Balmar alternator on our engine to our 100 amp-hour sealed lead-acid starter battery. From there a Renogy 60 amp DC-DC charger takes the load from the alternator and puts it in a lithium profile and in turn charges the lithium batteries. It was a fun build!
I would be interested to know the difference between these result vs a puncture that didn't leave anything metallic inside. I'm guessing the nail is bridging the internal plates.
Been 7 years, but no. It is a reaction the the air itself. The nail being left in-place has plugged most of that exposure. Like if a stingray's barb punctures your heart, but breaks off becoming a plug. If you're a Florida-Man in his 70s, you leave it in, have the boat return to the dock, take an ambulance to a hospital, and have surgeons take it out; you live. The nail/barb plugs the hole, and lessons the results that the hole itself would cause.
Yes, it contains hydrogen, methane, oxygen, and carbon monoxide. www.researchgate.net/publication/279069810_Thermal_runaway_of_commercial_18650_Li-ion_batteries_with_LFP_and_NCA_cathodes_-_Impact_of_state_of_charge_and_overcharge
@@GRBtutorials Only in high concentration, and even a dozen of these batteries smoking wouldn't be enough to cause any harm before you would notice it and leisurely stop your car or walk out of a building.
So here's my question: say you were in a situation where escaping smoke would be deadly, and you wanted to build a metal box around the thing to contain the smoke, How much pressure do you think it would have to withstand?
+Ryan Cook The process is exothermic, solvents are vaporized to gas - and the upper bound is the limit at which all of the aqueous solvents are in the gas phase. Say, that's 1/10th of the battery mass, for a 3kg battery that's 300ml of liquid. You liberate a few (3 or so) hundred litres of gas. In a 5 litre container that produces an over pressure of ~50 bar.
It was not a quick death. The battery would have run the Quartz Clock in the Workshop for the rest of your life. Did the battery still have any life after the execution?
Heh, if you did that to Lithium Ion, it would be a flame thrower. Why I am going to use LiFePO4 in my tiny house. I really would rather not have it burn down.
A lot of you are stating how much safer these are over lipos. You will be DEAD wrong when all that SMOKE fills up your house, bedroom or apartment. Don't tell me you don't do it because I see tons of videos with people just lying around their battery packs wherever they please. If the fire don't kill you the "SMOKE WILL". It's not surprising the battery makers do not explain that detail. If they did everyone would still be running nimh.
LiFePo4s are touted to be extremely safe. That's why my ride has one. Thanks for proving it!
but the smoke can kill you
@@JonOffgrid Probably not

I swear I can smell the smoke watching this. Oh wait, its my oven thats burning my TV dinner..............Folk!

No. it is not. Glad you enjoyed it!
That was MUCH tamer than I imagined... good test
How many geese were harmed in the making of this video?
Just one. Dinner.
The open question: is the smoke flammable?
Thanks for the video.
Mathieu
Also... is it toxic enough to be banned from the living space?

@@kevinhu4491 Same as a fart, totally safe (usually).
PrimalMiltos Carbon monoxide is toxic, though...

That is one amazing Vape where can I buy and does it work with salt nicotine
seems much more docile than a lipo
i wonder what would have happened if the nail hadnt stayed in it

What’s the liquid coming out?
I wouldn't have wasted a 36Ah cell, I'd buy a boost converter, solar panel with MPPT charger and use it to run the shop radio.
how else he going to show the test huckleberry?

Is the smoke toxic to breathe or contact with skin? Does it cause any trouble/irritation to breath or touch?
Yes, yes, yes and yes.
I imagine it wouldn't be very pleasant 😄
At 4:20s that little square blue guy looks high AF.
the nail cause the cell to shorted
I have 50ah lfp battery how much maximum current i can use to charge it?
They didn’t get fired . It’s very safe for storing at Home
We use them on our sailboat
We now know it contains Romulan blood.
At the time of the puncture, was it fully charged? It it was, I must say that I'm impressed. It is safer, indeed. But nothing beats lithium ceramics.
Its like Chernobyl PS crash in 1987
I would love to see a true C rating test of a CALB cell since they are supposedly underrated

Yes but the outgas of the LifePo4 will not cause an out of control fire like a regular Lipo will.
You can also call this the 'silent sweet death', for me at least as dangerous as a li-ion
