I just put a fully charged battery on my P2 and did some passes of some mini icebergs at the edge of Lake Michigan. When my FPV readout said I was at 40%, I decided to do one final pass, but after about 10 seconds of flight, the battery read out on my iOSD became 6%, and to my horror, the drone lowered itself into the water. Has this ever happened before? I have no faith in the batteries now. Can I make a complaint to DJI about this?? It was a warm day. Nothing to detrimentally affect battery life. (My friend donned a wetsuit and swim out to look for it but it was too deep, with zero underwater visibility and too f**king cold to properly look for it) Feeling terrible.
