This week I received the Tello DJI .
I charged the batteries and made about 3 flights, than I got the warning message that I am using an non-official battery ?
I tried all 3 (fully charged) batteries but the warning keeps appearing. I checked the firmware and I receive the message that I have the latest version. But what ever I am trying (5 sec restart / another battery etc) the warning keeps appearing and the drone is not flying anymore.
Does anyone had a clue?
