Had an interesting issue today. Went to charge my battery which has been sitting for a couple months now and when it finished charging the 3rd LED was blinking twice then off, pause, repeat. I pushed the on button and the battery showed all 4 bars. When I turned on the remote and powered up the P3 I get this message: "Battery Cell Broken", "Stop using battery and contact DJI customer service" Well, I did contact customer service so I'll see what they advise. The battery has only been used probably a dozen times. I tried another charging cycle but the same thing happens at the end. I was thinking I would discharge the pack and try again, but I can't run the P3 at all as the remote won't do anything at all when that battery is in the P3. So I'll wait to see what DJI says about it before attempting to discharge the battery manually.
