My experience is that the two red LED will not blink when I plug the USB into computer USB port.
They will only blink when I plug into a AC adapter and it will go off in about 3-4 hr after fully charged.
I do not know whether the LED will go off or it get fully charged when it is plugged into a computer USB port. :idea: :idea: :idea:
I actually got a response from DJI Technology about the battery charging time, heres what they said "The camera should take 3-4 hours to charge. The light will go off when it is fully charged. If your camera is taking longer to charge, please drain the camera battery till it is dead and try a full charge." I thought your not supposed to drain lypo's.
