I have abosolutely no idea why you would think that...:lol:

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.

Here in South Dakota we like to dispose of old batteries in a big fire....:lol: It makes the night more exciting...

From my experiences, "AA type" (AAA,AA,C,D etc.) batteries are really loud when they explode. I haven't burned a lipo yet, but I have an old lipo cell phone battery I will burn next trip to the farm.:yipi:

btw I'm not a pyro,,, Just a wannabe redneck.:party:

I'd believe its a chemical reaction that causes puffing before I'd buy into the compressed material theory. A material that can be compressed has an open cell structure (ie., foam, or at the micro level, air). Neither of these are considered high on the electrically conductive scale. I think that right there exhausts my knowledge on the matter......!!!

You live in South Dakota....you can't be a redneck....much too plain jane.... (I grew up in eastern MT, so I know, I tried too>>)

makes sense, I get alot of my info from the 65 year old guys at the "airplane park" here, Cant say there isnt a bottle of scotch floating around and tales of the great white whale.. they do have RC planes bigger than my house though

Well lithium itself is very reactive to oxygen, idk about lipos but the AA lithium batts have a lithium metal foil in them, when exposed to air it turns dingy brown very quickly and heats up slowly
