Anyone get a battery from Banggood and it works? Mine came in today. Charged it. Installed it. Started props and immediately got a warning on the tablet "Non-DJI Intelligent Battery Detected. Aircraft flight prohibited." and the props shut down. All the while, the rear LED flash yellow. I understand (after reading some posts here) that I should revert my DJI-GO app 1 version. Why would I do that and what would I be losing by doing that? Also, HOW do I do that? I just posted a claim on Paypal, but I really want this to work. Suggestions?
