Hi all, I just went out and flew my P4 running newest firmware ( i kno peeps want it listed to be sure), I have been flying a while on this fw with my mini ipad 2 and had no issues. After a coupleof fly bys I decided to shoot out to a distance I have flown many times before. When I got too 5500 feet out and 200 feet up, I heard the low battery warning, when I looked down battery said 72%. Needless to say I turned around and with my heart pumping I flew straight back home. There was a side wind, my P4 was tilting to compensate for it when it was coming in, and I was flying in sport mode, not sure if that had anything to do with it. I landed, restarted my bird still 58% battery life, and flew around a bit more, not too far out this time, but dudnt get the low battery warning untill it hit what its set @, I have low battery warning set @ 20% and critical warning @ 10%. Looking @ battery setting when this happened, and checking advanced setting, showed me everything was fine, even tho the low battery warning came up @ 72%, it was quite scary to be that far out and get that warning, any idea as to why this may have happened?
