Another hobby of mine is radio controlled aircraft. These all use lipo batteries, a derivative of li-ion. These things are seriously dangerous! Many charge them in ammo cases - preferably in an outbuilding...
Yes that's usually when things go wrong. If you store them at the proper voltage (~3.7V/cell) they also have less energy to release.Oh great! I've got a few of these and a load of NiHM's....and a load of gas canisters all stored in the same room. I'm assuming they're only dangerous during charging or if you puncture them?
After this happening to me last night.
I thought it prudent to post this and warn others to be careful when using rechargable cells. I have to do some tests to determine if it was a faulty battery or a faulty charge controller that caused this, but either way its a wake up call.

It "was" the second revision Ram tester prototype...
I managed to determine that the charge board is working fine, but the cell was faulty which caused it to fail. I will only be buying the better brand cells like Panasonic and Nexcell from now on.
It was a 14500 cell, so not a lot bigger than a AA
Got a cut to my wrist where something hit me and some minor burns to my neck from the gases, but otherwise ok.

just think of all the Teslas and other milk floats - driving around with ya **** on explosives!
You are dead right Col you don't get a 5 Star NCAP safety rating with a load of LiPo cells under ur A*** as Neil mentions lolI’ve blew a few big ones on purpose as you do when out with mates flying models/drones.
Yep nasty things in home environment but I’ve never seen one fail like that before was he messing with it or summit.
When lipos start to fail they generally swell badly and a decent charger shows each cells health. Hence blowing up the old ones out in the wild.
I’m sure cars have a different setup which prevents this even in a bad crash.
I’ve got few mates who work at Nissan and the have a battery plant.
pablouk should know he gaffer there
