I just finished updating iPad OS, the P3P 1.06 FW and five batteries FW. Everything went fine. No issues. The aircraft was double checked on the bench for a successful FW update and each battery was reinstalled into the aircraft to confirm each FW update for them was succcessful. I charged all the batteries to 100% and went out to do a bit of flying. The first two batteries were fine. Phantom flew flawless. I installed the 3rd battery and immediatley noticed the battery led in the center was blinking but not the leds on either side. I looked at the the DJI Go battery display and it showed all cells in the red and the display reading Critical battery Error 9 volt. I turned the aircraft off, pulled the battery, reinstalled it and everything came up fine. My first thought was that the battery did not seat properly but I always make sure I seat the batteries and then double check the latches. I am positive this battery was secure with absolutely no movement. The rest of the day was uneventful though in the back of my mind I kept expecting a battery to fail. Has anyone seen an issue like this after the 1.06 FW update?
