I've done only 17 flights to date and have always seen 100% life on my stock battery. Today I charged it and when I started the P3 up it said it only had 91% battery charge, fresh off the charger. Also the battery life was down to 83% from 100% yesterday. At this rate I will have a dead battery in a month. Surely they should last longer than this! I've been flying in temps around 100F or 38C and the battery is too hot to hold when I take it out right after a flight. Would running the P3 in the heat be killing the battery? Would cycling the battery fix this? Thanks!
