My one year warranty just ended and before it ended I had a battery replaced at no cost from Autel. It said damaged battery when I flew it. It had less than twenty cycles on it. Kudo's to Autel.. This afternoon I flew again, and damnit if it did not say damaged battery an returning to home. This was on what I named as battery three. Fortunately everything was fine with the landing. The problem still exists with battery failure . It was too late to contact Autel this evening but will get back with them in the morning. I will keep everyone updated and look to hear from anyone else with their issues.
