Hi guys I'd like some help about DJI P2 battery life. I have one that after 31 flights has 90% of life. I have read a plenty of articles and watched some videos about not flying bellow 90% of life, but I wonder if DJI wants us to buy more batteries or the battery is really almost dead. I have flight other day and seems to be OK. I'd like to hear a bit of you about it. I'm not very good about electricity concepts, but this battery seems to be OK, when it's fully charged the cells are like this: Cell 1: 4139mV Cell 2: 4138mV Cell 3: 4135mV Overall voltage is 12412mV and the current capacity is 5076mAh and shows the actual full capacity as 5153mAh. Do you know if I can trust those indicators or it's better to retire this battery?
