I just received the new Mavic 2 Enterprise last week. Charged up all the batteries including the RC. I’ve flown it twice and tried to recharge the RC battery today. It makes a high frequency buzz at the controller, the micro USB end of the cable from the charger gets warm, and it will not charge now. Any suggestions on what might be wrong? Sounds like a bad connection to me. Support was not open today but I’m afraid they’re going to tell me to ship everything back tomorrow.

Hi GPPilot, we're sorry for the troubles. Is there any chance change to another working cable to verify? If the issue persists, please kindly upload a short video of your operation, we'll double check, thank you!

I tried several cables. All had the same result. I doubt you can hear the buzz in a video. It sounds like a mosquito, not loud, and high pitched.
