Summary:

During a training flight with the battery level indicating 12 minutes of flight time remaining, a 鈥楲OW VOLTAGE BATTERY WARNING鈥� 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 鈥渃onsiderable speed鈥�. The UAS manufacturer determined that it was caused by a battery firmware problem and has issued an update.
