Hi, I've been flying my Vision for couple of months. Today I almost crashed it due to sudden power decrease in my batterty. It was around 100 meters high with 38% battery left, but suddenly I got a warning on my screen saying that I have to bring it home. And at that moment the battery fell down to 7%. I barely reached ground. Any ideas why this happened? Now I became paranoid. I am not sure whether I should trust the battery level anymore.
