So, I was reading about deep cycling DJI Smart batteries, and most specifically my Inspire. It said after conditioning using the 10/10 method, and then every 10 charges thereafter to deep cycle the batteries. I decided to do that on my P4 batteries today. So my first battery, I fly the Phantom, whose battery was at 100% charge btw. Outside temperature was 81F. I flew it like normal, and actually hovered mostly, but some runs here and there so i wasn't bored out of my skull. I checked the battery at around 17% and it was at 62C! By the end of the flight, at 8%, it had reached 67C, and I thought there is NO way that can be right, nor good. The P4 itself was fine, standard "warm to the touch" as it always is, nothing special or extra hot, but battery, while warmer than normal wasn't out of sorts warm, and I could hold it in my hand. After searching the internet, and finding LOTS of info about P2, P3, and what not, I did not find ANYTHING on the ideal / MAX temperature for the P4 batteries. I know it says you shouldn't fly if the temperature OUTSIDE is 40C, but that is the ambient temperature outdoors, not the battery temperature (besides, EVERY single user would be outside that scope unless they live in an extremely cool area all year round). DJI manual, no help. The battery itself, no help and no markings leading to such (unlike the P3 and Inspire batteries, which are marked with max temps). Anyone have any ideas what the max temp is / should be? Did I exceed the threshold and ruin one of my batteries? Any info greatly appreciated.
