My tello has the original genuine battery but I’m getting “unofficial battery” message and unable to fly. The Tello edu and battery are with Ryze support at this time but they have no real answers yet. I’ve read online that others have the same problem and some associate it with a firmware update. The battery charges and holds its charge fine. Does anyone have any ideas? Also how does it detect a genuine battery, is it the firmware or the app interrogating a chip in the battery?
