Hello, I have a question, about P2V battery cycling! They say, after every 15-20 charge cycles, you are supposed to " Cycle " Or refresh your batteries. They say discharge to no less than 8% ( or until battery no longer turns on , then fully charge batteries! My question is: Is 8% through the app ( % ) or ACTUAL 8% on battery? I take it to 8% through app, but battery still turns on? Am I doing it right? Thanks for any assistance! Take care, fly safe!
