I noticed it's a 65c pack, these are known for having issues when left fully charged for long periods of time. Keep in mind they are the biggest fire hazard when sitting fully charged. I would reccomend doing a storage charge after your done flying and not charge them till the morning of flying. This is safer and will make your packs last longer.

I fly big EDF in addition to turbines (several 12s 8000 mah setups) and have had the best success with the method above. I run A123 (2 in parrallel) for all my RX's and a single 3s Life for my ECU's with the exception of an older P120 I still have, it has to run on a 2s lipo....
