I'm new to the p3 pro world. For some reason my DJI batterys are talking all night to charge. The battery's have only been charged 9-11 times and show 100% health. I am using the DJI 100w charger. When unit was new the battery's charged in about an hr. I have tried to take one batt down to the 8% but that does not help. I have also tried charging with power on. Still no good. All lights flashing like they should. Please help.
