I ordered 2 extra intelligent flight batteries from Camrise on Amazon ($219 for set of 2). Charged and plugged into my P3P and updated the firmware. Visually the battery is identical to the one that came with my Phantom. However I noticed the following differences in the DJI GO app: 1. The total capacity is 4380mAh 2. The cells are out of sync I contacted the seller who claimed "they are original DJI batteries and he doesn't know why or how the readings are coming up as they are" So I guess my question is whether the reading is normal or if I should just return them and order a new set. Only draw back of returning is it'll delay my maiden voyage planned for this weekend...not a terrible thing really as it'll just give me more time to re-read the manual.
