This was a rather odd and insane experience...
I had just flown the drone for about 45 minutes on two batteries consecutively Brought it back to the LZ to deploy the third battery, and then continue filming.
On this third battery, I got into the air, flew to a target (which was about 400ft in front of me), set the POI mode target, radius, and altitude of ~100ft); flew for probably 10 minutes total having around 70% battery left, everything was going great.
All of a sudden, the DJI Go 4 app says aircraft disconnected, and I can no longer see or hear the drone. I try to restart the DJI Go app with no success. I still have telemetry on the controller, saying it's 400ft away with an altitude of 113ft. The last GPS location on phone is not where the drone was, nor could I see it where it "should" have been on the POI radius. I press the return-to-home button, and I finally hear the drone. It's not exactly where the RTH was set, and it's above/behind a tree line, but I'm able to increase altitude and hear the sound of the props.
I'm able to walk out away from a tree line, and the drone is still moving in a POI pattern, but near the home location. I'm able to get it in a clear field, but it's sticking to the POI motions, even after I try the "pause" button on the remote. I try to orient the drone and move it closer to me, but the controls are inverted, and seemingly keep changing, which was really weird. I'm trying to fight the controls to get it back over towards my location, compensating for what the POI pattern is doing, but the controls keep changing how they are reacting... finally I'm able to pull the controls around enough to hold it somewhat steady in line-of-sight so that it's not disappearing and blending in view of the background and drive over to it.
I try to make it land, but it won't get lower than 14ft. I drive the UTV close to it and am able to stand on it while manipulating the controls and grab the drone from the bottom, but then tries to aggressively climb as it thinks it's avoiding an obstacle (I suppose?) I try the emergency shutdown procedure on the remote but it doesn't work. I carefully move the drone around and down so that I can take my other arm and get to the battery to shut it down that way... that doesn't work at all. Finally, after holding it for a bit, the critical battery actions take over (at least, I think that's why it did this) and the drone just shuts down.
Once I get back to the office I try to power it on and connect USB, but it doesn't even connect or recognize it... not sure if this is related now or not.
WTF just happened? It's pretty warm here today, around 95F... and this was the third consecutive battery in this thing. Is this some sort of weird behavior from heat?
