Good Evening guys,
Trying to help out a friend, we both fly phantom 4 drones and just tonight his drone fell out of the sky. The red and green lights appear to have turned off and connection was lost, motors powered off. He cannot recall but the battery lights seem like they were still on when it landed on the ground, but the battery was out of the shell from the impact.
It happened shortly after take off (22 seconds in) and about 20 feet above the ground, some serious damage but we are looking into some possible causes for this as the unit is out of warranty. Battery has 27 charges on a regular capacity unit 5350 mah grey p4.
I uploaded the logs to UAVdata of the crashing flight, I dont see anything out of the ordinary except for the battery temp being near 50C.
First few flights before crash -- where battery temp looks high to me (uploaded logs under my account)

The following errors were on his part and im just trying to make sure it was not a drone issue:
- flew about 2 hours total today
- battery was charged erratically
- flown from 95% charge to 25% charge, landed and put on charger immediately up to 65%
- then thrown back into drone at 65%
I deduced the above and he has a rough re-collection of yes being rushed to get some shots in the nice weather. The battery was not left to cool between charges, but would it cause this ??
Could the random charges and high starting temp (near 50c) cause the battery to just turn off randomly, or was it a battery disconnect ??
We fired up the drone just now, motors turn on, sensors work, but camera is fully smashed off.
This is a P4 regular 12mp model.
Any info would be greatly appreciated before we start working on this bad boy (out of warranty).
