I just received a third party battery I bought from Ebay. 15.2V 4500mAh 4S Intelligent Flight Battery DJI Phantom 3 & Phantom 3 Standard Took over 5 weeks to ship and now been trying to figure out how to solve the "battery signal error" problem. Been trying with 3 different firmware's and reinstalling DJI GO a couple of times, but nothing seems to help. Read plenty of reviews before I purchased it from people that had good experience with it. Thought I'll ask if someone here had the same problem and if the managed to solve it.
