Hi. Got my P 3 Pro today but have not opened the box yet. I know that I have to update multiple batteries. I have two. After I have updated the controller, a battery and the P3 ... at what point do I update the next (second battery)? Looking at the problems I have read about .. I am really worried about this process of updating :-(
Much obliged.
