I recently had an issue where my quad overheated inside my carrying case (battery powered itself up); it now wants to fly away, so I have sent it into dji for evaluation (I know now to remove the battery when not flying). I want to discharge both of my batteries to 30-50%, per the manual, because I won't be using them for several weeks. When I turn them on, though, they won't stay on. The one that came on inside my bird and caused the overheating will only stay on about 5 minutes and then it shuts off (tried this three times). The LEDs and power button light are all noticably dimmer on this battery compared to my other battery. My other battery shut off sometime in the next 3 hours, but still shows nearly full charge (four lights) when I powered it back on. Anyone have a clue what is going on here?
