My neighbor and flight buddy recently purchased a M2Z and everything has been great...until today. Three of the batteries, once installed, DJI Go 4 says that the battery is completely discharged and can not fly. When he goes to check the battery data everything appears blank. However, the batteries are completely charged and they light up the green circle when the button is pressed. When we went out this morning he had that issue with 2 batteries. After recharging all batteries upon our return home, the same 2 didn't work and a third developed the syndrome.
Any ideas?
