Can anyone recommend a good reliable 4S, 14.8, 30C long lasting battery for that airplane? From the other brands that I used all of them got puffy after a few 6-7 min flights.
Your comments are highly appreciated.

My two comments here are ;
I have never had any LIPO battery that lasted longer than Hyperion , with ThunderPower being a close second .

If your puffing multiple batteries in a few 6 or 7 minute flights your likely drawing too much current out of them , try reducing your prop pitch a degree or two (replace a 10-7 with a 10-6 or 10-5 for example) .......
