I bought a used Autel Xstar premium drone. When I plug up the remote into its charging side it charges fine, but when I plug up the battery into its side it won’t charge. The little green light that is supposed to come below the fan isn’t coming on either. It’s almost like the battery charging side of the charger isn’t getting power, but the remote control side is. Has anyone seen this before? I have tried using a different outlet. I have unplugged from the remote and still nothing. I don’t know why one side of the charger would be getting power but the other side isn’t.
