    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)
