Previous owner of an original Phantom and Phantom Vision. Picked up a Phantom 3 (Pro) today, but when I insert the battery the Phantom 3 powers up immediately, without even turning it on. It will not power-off. The battery will be off when its inserted into the phantom, but it just powers up and will not power off. Practically like the Energizer bunny. Yes, I waited roughly 10min or more and it doesn't power down. I updated the firmware, same thing. Put the battery on the charger, doesn't want to charge, unless I power the battery on. I don't get any battery error messages until I power-down the Phantom 3. I'm leaning towards defective battery. This one issue has put a whole buzz-kill on my Phantom 3 experience. I'm more concerned with this issue coming up mid-flight and causing an incident. Any ideas? Frustrating. After all these years its sad that DJI still hasn't solved the battery issues.
