So I noticed with my 2 DJI batteries and 1 Powerextra battery, that 1 of the DJI's always asks for a firmware upgrade when inserted in the AC. The PowerExtra and other DJI battery seems to be updated and this occurs from my iPhone or iPad when I launch the DJIGO app and it connects in the flight screen. But the battery that "needs" the firmware update was flown today, so I am waiting on the charge process, before I attempt.
Is this normal, that the last time I did a firmware update, that 2 batteries got it, but 1 did not?
