Yes not exactly easy to understand unless you know what to look for. 😆
From what I understand is to just look at the 1km and 4km text on the right side of the graph and see if it’s right next or above the line.
DJI has an SDC cable which plugs into the Mav 4 Pro charging hub instead of the battery itself. Have one coming from Shenzhen, China as they’re not available anywhere here.
