My LiPo just exploded

Okay I had a 3S Lipo which I over discharged and wrecked, so it was only useful as a 2S. That was useless to me as nothing I have runs 2S. So I, rather stupidly, peeled the label off with a knife to see if it was possible to replace a cell or to at least see how these things work. (Yeah - seems stupid now I think about it... we all do stupid things!! ) I did however think about the dangers and had a tub of salty water to dispose of it nearby in case it went bad as I heard salt water is good for making lipos inert.

And it did go up. Luckily I thought about the water. I must have punctured a cell because it basically burst and smoked everywhere, so I dumped it in the tub, and it seems dead now, but what do I do with it? Is it safe to dispose of? It's been in there for about 15 minutes.

Salt water disposal is a myth that just refuses to die.

LiPolys are safe to dispose of after being discharged to below 3volts per cell,the lower the better. Myself and many others use an auto tail light bulb to discharge them.

Yeah, so what do you do when the pack is simply on fire? I dumped it in my prepared tub and it stopped bubbling after about 30 seconds. Not sure if water is also an option but didn't want to take any chances. I wasn't trying to dispose of it, just trying to stop it exploding / burning.

Dry sand is a better means to control a flaming LiPoly.
Next time use a plastic picnic type knife . Most likely you either punctured the cekll and cause a short or just shorted the contacts.

Didn't have any sand but would a tub of salt (with no water) be good enough?

Pack voltage now measures 0.14V. Two cells are completely dead; one measures 0.14V. So can I just chuck it?

The ref you heard about salt was associated most likely with soaking it for a long time for discharging, not extinguishing. Your result would have been the same with water alone. Sand is preferred as Charles mentioned.

Twist the leads together and dump it, yeah.

Salt should be fine instead of sand too, it won't burn.

Though i don't see a reason not getting 100l sand.

Your not suggesting that salt should be used in place of sand are you?
