I've been experiencing an issue with my drone's battery while trying to charge it. When I connect the battery, all the indicator lights turn green and start blinking continuously. Initially, I assumed this meant the battery was fully charged, so I disconnected it and reattached it to my drone. However, I noticed that the light indicator displayed just one light briefly before turning off completely, and now the drone won't power on at all. I tried charging the battery again, but it continues to blink with all lights green, just like before. I'm quite puzzled about why it's behaving this way and what the underlying issue might be. Any guidance or troubleshooting tips would be appreciated!
