Hi everyone.
I have a phantom 4 advanced and am using the high capacity batteries (PH4-5870mAh).
Around 5 minutes into a flight I got the 'Battery Damaged' message on the controller and decided it might be a good idea to get the bird home and land immediately. I did this without problems.
Checking on Airdata later I found something weird, screenshot attached below. I know battery cells can fail but never seen one cell go high and another low - a perfect mirror image of each other. Any ideas what might cause this?
I did try fully recharging the battery and then doing a nearby low test flight and the same thing happened a few minutes into the flight. Interestingly over the course of the log the problem appears and disappears, as you can see from the screenshot of the original problem flight.
The battery has done around 10 flights only and, at least I think, I've looked after it - i.e. I store it half charged, charge it fully before a flight, let it cool before recharging, etc. Unfortunately its just over 1 year old so I don't think DJI would do anything - maybe its just bad luck and I will have to relegate it to the bench for powering updates and stuff.
