I lost my P3P last week so I am selling off my P3 accessories since I replaced it with a P4Pro. What I am noticing is that everyone selling used batteries claims they have 2,3 4 charges, etc. How is this possible? I can see if you lost your drone after a few flights but I suspect these people are resetting the battery charge cycle count. My batteries work great and I can't check the count anymore (no P3) but I am sure they have at least 15-20 on each of my batteries.
