I have flown my Phantom probably thirty or so times with almost zero problems. One thing that has happened is I have gotten a warning that says something like: battery connection failure, fly with caution. The warning stayed there for just a few moments then went away. The battery level indicator was constant and nothing else strange happened on that flight nor another flight where I got this warning. On subsequent flights with the same battery no such warning occurred. Has anyone else experienced this or knows what is going on?
