Can someone look a crash log for me please?

I had a crash(bad) It is Hexacopter zd860 with 2 x 6S Batteries. It hovered at 5m then went to 20m that was expected then turned on it side and fell out of the sky from about 20m. I have tested both batteries and they have about 4.08v in each cell (batteries are new never used before).

It looks like a mid air power failure as your log stops at altitude.
