Got my M5 yesterday so I am just a day into learning about it, still very new to Freefly products. I got it fired up and camera mounted and played around for awhile and worked great and now both batteries need charging. So when I plug either one in only the green light blinks. Switched on LiPo and 1A since it's the smaller M5 battery. I even left it over night to charge and it's still dead. what am I doing wrong?
