My P3A, RC, and original batteries are current on firmware. I just purchased a new battery that needs an update. I read a previous thread that said just to insert the battery and slid something over on my DJI GO app where it says the battery needs a firmware update and it would update. Is this correct or do I need to download the latest firmware on SD card and go thru the whole process as if I was updating the aircraft with the new battery in it?
