    Picked up the P4 today with an extra battery.

    Updated the drone and controller no problem. Powered everything down, put in the 2nd battery and turned everything on. Everything shows up to date. How do I update the firmware on the battery?

    Should automatically detect the mismatch and prompt to do the update. At leasts thats what it did for my two spare batteries.
