Damaged Lipo, Disposal?

Something I was told, by an old timer. Lipo cells are vacuum sealed and if it was punctured it would puff as to regain our atmospheric pressure. I.C., I.E. if it ant puffin it aint busted

Nah, they are not really vacuumed that tight. They are airtight, that is why they puff when you overdischarge them and the chemistry alters...

I have purposedly damaged all kinds of lipos in all kinds of ways. I have a feeling that a tear in the pack lets air in and that causes issues. Not like a lead acid battery that does not care about air. Maybe the paste is oxygen sensitive?

Anyways, I have also salvaged many near 0v cells... If they are discharged slowly with a very small draw, they can be revived with a very slow charge. As long as they have not puffed...

From my experience the cheap chinese cells seem to not puff as often as the name brand cells when let drop below 2v... Truerc cells are sturdy, I run them with no lvc and just charge them slowly, in my 10th scale stuff and crawlers.
