I took my P3 out to the beach to get some footage of the Gulf Coast of Florida. I had a fully charged battery and calibrated the aircraft got the green flashing go ahead and green Safe to Fly (GPS) on my DJI Pilot App screen, took off and flew up and down the coastline getting some great footage and photos. I continually was monitoring all of my signal levels to ensure a safe flight since I was over water, just off the coast, less than a minute before the failure I had 51% battery, shortly after, just over 10 minutes into the flight an error message popped up on the screen, it had a red triangle with and exclamation point in the center and said Critically low voltage, the aircraft will land now, I hit the return to home button and the controller started beeping and my FPV went out and the Phantom 3 professional never made it back and I tried looking for it but could not find it in the water. Has anyone heard or had anything like this happen? I posted the flight on youtube, I am hoping DJI does the right thing and replaces it. The video can be seen here. Thanks for any advice.
