I truly feel for you. I may still be able to find mine, launching a expedition this Sunday to look for it at the bottom of the lake. <Image removed>
sure, he has 6 Phantom3'sMaybe has other quads and forgot to mention that.
That was already mentioned and the answer was givenFrom the image it looks like you did a CSC emergency shutdown at 55 feet in height...

Several people on this thread stated you should post the video, but it is my understanding that the only thing you have left after an accident is the flight path information. The video and photos are not on the table, only on the SD card. Am I correct? I know it is different if you are "live streaming" but for most flights the video and stills are only available if you can get the micro SD card.
There are ways to "transfer" from the SD card to the tablet, but that takes quite a while and is not practical during an actual flight.
If not a poorly inserted batt, my belief the next likely cause is a bad cell or even a dumb *** smart battery. I say this off my experience with 3 P2's and soon to be P3 pilot. And of course we are going to fly over water, we fly where the beauty is. My favorite is the nudist camp or White House lawn (kidding). All 3 of my P2's have severe crashes due to the failure of the battery as described above. The most recent this week gave me some ideas to research. As before on the previous 2 battery failure crashes, battery was firmly inserted and this time was hovering only a few feet from me for the purpose of running batt down to approx 50-60% since I had not used it on the weekend and may be weeks before using again. All normal until 79% and 11.1v**, suddenly it went to 10%-10.8v, batt icon was empty and flashing, red LEDs flashing and going down fast. Being close I reached to catch and just as quick the voltage shot back over 11v, didn't notice what the percentage was with the chaos, but everything returned to normal seemingly. As I stepped back it immediately went back to before with batt now showing 10.6v and less than 10%, as I caught it I continued to apply power to watch the battery readout. It would alter between a reading of 11.1 or .2 or .3v running strong, to 2-3 seconds later back to 10.4 and falling, with motors going to auto land. Each time the batt icon would show 3/4 full to blinking empty. The back and forth almost seemed like a loose connection with the abruptness of the changes, but now each swap in v readings on the lower end keep getting into the range I thought this thing would not do. It hit 9.8, 9.6, 9.3v and somewhere along here the motors finally shut off. I charged it back up later and after the second flashing light went to solid green, it stopped charging, but pressing the batt button shows a full charge. One of the other failed batt did the same after reaching the third solid green light, can't remember details of the first batt. The Assistant SW showed no indication a problem with the batt, but the cell voltage readings were off a little; 1 3880 2 3815 3 3879. This mean anything? Today I will remove the cells, and try to rebuild using the best cells from my P2 batt infirmary. I'm not sure how to pick the best or identify the bad ones, they all are reading close in volts (smart cap problem?)
With amount of money invested in the pricier drones, in my opinion the battery does not give me the confidence I need my investment will come home tonight (like my ENRON investments). I wonder if a electronic device that can automatically kick in with a batt failure with just enough batt juice to get something like a P2 or 3 say an extra 50-100' for an emergency landing. But thats added weight and cost, plus you add another failure potential. I like the idea though.
**Some values I am not 100% correct, but it definitely got down to the low 9s, thought it shouldn't;t even run that low.
LET Me add an update.let me add an afterthought . the battery was seated. when I recovered the drone it was hard to pull out. the battery after recovery was dead. Don't know if it died before or after it landed in water. the above picture shows most of the flight was over water. Actually it was mostly over land
Yes and the DJIFlightRecordxxxx].txt has all that data - volts, amps, watts and battery temp (amongst others).Here's a way to assess the health of a [LiPo] battery:
