Here is the thing that happened to me looking for somebody to throw some light on it. I bought a battery about 2 weeks ago and the battery show on the app. that haven't been charged ever , so I presumed is new. I had used the battery for about 4 flights with not problem, now yesterday I was using that battery and flying at a distance 6000ft and 125ft hight when I get a message about battery error , I decided to bring the bird home immediately and I barely made it. Note that before the warning the battery was 70%. When the bird landed it was showing 60% still with the battery error on the screen. Today I charged the batería again and show fully charged , put it back on the phantom and show 0% charged and all the cell show 0%. Any help with this?
