How do you keep your older Autel drone flying when new batteries are not available? I tried everywhere and was unable to find a new battery for my four year old X Star Premium Autel so had to "park it" as it is down to less than ten minutes flying time on a full charge. It has been a very good drone and did everything I needed it to do but the lack of support for batteries means I now have a DJI Mavic Air 2. Very disappointed in Autel for not supplying new batteries for a four year old drone.
