    140 is considered absolute safe maximum for LiPOs but that's too hot for my liking.

    Mine seems to always hit 61 c which equals 141.8 degrees

    I'd be shortening the flights a little while it's warm out. You will get a lot more out if the packs.

    It's only 77 degrees or less outside. Seems a little hot to me. Might need to exchange the P4

    What battery % are you flying down to? They get hotter faster towards the end.

    For you temp rise is 142-77= 65F

    So if the ambient is 104F, battery temp might go to 104 +65 = 169F if all is linear. Most docs say max safe temp is 140F, few claim 160F.

    (104F is the specified max ambient for P4)

    Between 30 amd 20 percent. Now both batteries say 99 percent health .
