I'm running a Rimfire 35-30-1450kv, silver series 40A brushless ESC, and a Thunderpower 2100mah lipo 11.1V in a elec yak. After 5 mins of flying lightly, I brought it in because the wind was getting too gusty. When I was turning if off I noticed the lipo was swollen, obviously can't use it again. But why would it cook like that? If I were flying my normal 3D pattern for 10 mins, the plane would have caught on fire. All the connections were good, just a swollen battery. It wasn't hot either, just swollen. Any ideas?
