RE: exploding lypos
Overcharging seems to be the biggest danger. I've never had a lipo explode but here are some vids.

Not something i would want to mess around with and I wouldn't trust it after it swells up.

RE: exploding lypos
Sounds like your friend is discharging his batteries to low by either running them with a larger setup than the battery can handle, or not setting a lipo cutoff on the ESC to engage soon enough. Either way a swelled cell means an out of balance battery. You then run the risk of explosion by charging the battery without a balancer. I would be careful.
