Narrative:
AAIB investigation to DJI Matrice 210, (Registration n/a): All four electric motors stopped due to a battery firmware issue, near Albert Bartlett Farm, St Helier, Jersey, 20 December 2017. The AAIB Final Report was published on 11 October 2018, and the following is the summary from it:

"During a training flight with the battery level indicating 12 minutes of flight time remaining, a ‘LOW VOLTAGE BATTERY WARNING’ appeared, all four electric motors stopped and the UAS began a rapid descent. A second later the warning disappeared and the motors reactivated but there was insufficient time to prevent the UAS from crashing at 'considerable speed'. The UAS manufacturer determined that it was caused by a battery firmware problem and has issued an update".

Damage Sutained to Airframe=
Per the above AAIB Report "Damage to landing gear legs, front arms, two propellers, camera gimbal and battery case".
