Speaking of "on fire"...
It's called puffing and could be dangerous.

Lipo's can puff for various reasons like over discharge, high heat or damage.
Once a lipo puffs, depending how severely, it should be closely monitored and/or retired.

I have one battery that gets ever so slightly puffed after a hard flight. Once it cools it returns to normal. I keep this battery separate from the rest and I'm seriously considering giving it the salt water bath.

Lipo's can be dangerous, I keep all of mine in a fire proof cement block.
Continuing to run a puffed or damaged battery could cause a fire.

I'm no lipo expert but there is plenty of expert info in the battery/charger forums.
