Yesterday i was flying my drone and while it was in the air it shut down and fall. In consequense the case and the camera are broken. I need to know what happend and why. I can't understand how a drone can turn off in the air just like that, without any warning. The only thing that my display show was the message "battery error" in yellow, in that moment, the aircraft went down in free fall. The battery was 100% charged and secuered with all cells fully function. I'm looking foward to get help from you.

I attach the log of the flight in a zip
