After an Air 1 battery failure in flight, I went back over the history of that battery with Airdata information, and I really don't think I could have seen it coming. The battery is not swollen, charges normally and all the cells show normal. I have flown it several times after that incident at low altitudes in my back yard as a test. It fails every time in very short order because of a low cell.
