I tried to refresh FW with DJI assistant but no luck.Twice I got mismatched FW version and battery tried to update but still the same.
Batt n.1 no issue
Batt n.2 did have the same warning but eventually worked after few reboots.
Batt n.3 still the same after lot of attempts. Still powering Air Craft and it is fully charged.
Ps: back light is flashing red fast non stop
