Hey all,
So I am pretty new to drones, the Mavic being my first real drone. Anyway to the point, when I first got the drone and charged the batteries the first few days and flights, all batteries would charge to 100% and just under 12V.. Now, I fly the drone till batteries hit about 20-30% sometimes less, and recharge, but none of the 3 batteries(fly more combo) will charge to over 4V. They all hit 100% but just under or at 4V. Never higher. It might be normal, but manual, looking up on here, and internet, I cant find anything about this. Not in the manual for drone or batteries. Any help is appreciated, whether its simply saying thats normal, which I dont think is the case, or that something is wrong.
I only charge them the day before or morning of a flight, and I use the charging hub each time.

Thanks in advance

The rated voltage is 11.4 volts. It's a 3S lipo battery so there are 3 cells.  11.4V / 3 cells = 3.8V. You probably read the full battery voltage before and are reading a cell voltage now.

Im reading which ever shows up in the app when all connected.

did an update on DJI GO 4 change it to show cell voltage instead of full battery?

Must be. No way it could even power up with just 4V
