Hi, one of my Mavic Air Batteries has the two middle lights on for days. I am not sure how it happened exactly, but it's related to the firmware update. When I put it on the aircraft, the RC shows me "Battery error", and doesn't allow it to fly. I've seen some solution for the battery of Mavic Pro, like use PC DJI Assistant to deal with the inconsistent issue of the hardware. I tried to follow, but whenever I try to make the upgrade, it always fails because the battery power is less then 50% (though I have charged it for 3 hours, and the hub shows the stable green light). So anything I can do to save that battery? Thank you!

What worked for me with the Mavic was to put another battery on and go back to the previous FW . I then could boot up the Mavic with the affected battery and finally updated FW after that .

Thank you for your reply! How did you roll the FW back to the previous version? I see this on Youtube. Looks pretty complicated.

Hello.
Please tell me which version of .bin was downloaded from github? Did it help you fix the battery?
