For a longest battery life i know that must keep battery up to 80% from capacity. Never discharge more than 20%. But how you storage? You fully recharge after each fly and keep it on P2? I have read that is not OK to storage full charged battery. http://www.rctech.net/forum/electric-ro ... ltage.html 11,2 V for storage that mean need to charge just for 3 battery leds bar and full charge before fly?
