Why do Lipo Batteries "Puff up"

Yeah, the only problem with puffed packs is performance loss, you will slowly loose available amp capability as well as flight time. Otherwise no other issue. The only time I've ever seen an explosion was a rupture or a short that could be caused while charging. This is why you keep a close eye on your chargers and packs when charging

Heavy current draw as in an EDF jet causes packs to get hot and puff before their time. Recharging packs immediately after a flight, when still hot, will also cause them to swell. Batteries are labeled some number and "C". When new, they may be as advertised, but with use, individual cell internal resistance (IR) gradually rises and their actual "C" may be much lower than advertised. A moderately swelled pack may work acceptably in a low current draw model with reduced performance and flight duration.
