Anyone here ever experience a lipo fire? Raise yer hand!
I tried the fridge method once. The cold literally "freezes" the charge in place. No discharge at all, which is why lipos don't work well in cold weather without being kept warm.
Unfortunately - and I have not researched this so I may be spouting nonsense - freezing appears to cause a semi-permanent "rigidity" in parts of the battery. A brittleness, I guess.
Anyhow, I took some three-cell batts from the fridge a few years ago, put them on my bench overnight, then began charging one. Within ten seconds that red shrink-wrapped wonder started puffing up like a skillet of Jiffy Pop.
The seams split and now it became a smoke bomb.
Then the shrink wrap began blazing and the entire thing was literally roaring and spitting like someone had poured kerosene over it and dropped a match. A nice, cozy, extremely hot chemical fire.
Well, all ended well except that it burned up my charger, and I threw away the other frozen ones as well - no need to take a chance.
As I said before, this may all be idle speculation and BS of the purest ray serene... maybe the battery was just faulty...
But I really don't think so.
