Paul Buchheit's LiPo battery caught fire last night and burned up home office

LiPo's are used extensively in RC flight now (main power source for electric flight) and that group knows first-hand the dangers of these batteries. In fact, you can buy "charge bags" that are non-flammable incase your cell bursts into flame during a charge.

Great batteries, but very susceptible to over and undercharging with sometimes disastrous results. I basically never leave the room when I charge mine.
