today i helped a fellow flyer set up his MPP and i found something interesting in the battery settings in the app,after they were all updated i was showing my friend how to access the battery info in the app and under the heading about, it showed the date as 2019-07, all the three batts were the same ,i was under the impression that that was the date of manufacture, it was a brand new MPP flymore combo purchased from a approved DJI dealer here in the UK
