Recently I had a similiar problem with one of the TP 3S4P 8200 packs. After the 3rd 5 min. flying session on the Lazy Tiger P51, I saw that the pack had a "sausaged" cell after I removed it from the plane. The motor is propped for 40 amps max. with a cruise of about 30 amps or less. Previously I had been conservative and flown two 5 min. flights with 30 min. cooling between flights and after charging it appeared I had only used about 4000 mah. Voltage was still way over 10 v after that 3rd flight. I measured all component temperatures after each flight and the battery pack was only 115 deg F (with a 92 deg F ambient). I sent the pack back to TP but have not heard anything in weeks.

Lately I have been thinking about going back to glow for my couple of prop planes and reserving this LiPo stuff for my EDF jets. They are still a great advantage in those applications. I get 2 x 5 min flights with my F-18.
