Summary:

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.
