I just purchased a DJI Mavic Pro and right out of the box when I try to charge the battery, LED1 (The 1st LED furthest away from the battery button) flashes every 6-7seconds for 12-17 times. I've tried charging for several hours and got nothing. Everything is fine, no temperature concerns, etc. I've scoured the internet for hours and posted on the DJI forums. NO ONE has a clue. Can anyone here help?
