Persistent current: 3A Instantaneous current: 5A Supports 1 x Lithium battery; Does not support Ni-MH battery Functions: - Control motor to rotate clockwise and anti-clockwise to meet different requirements - Safe power on - Signal loss protection - Will reduce temperature by limiting power when temperature is up to 105'C; If the temperature still goes up after limiting the power、 it will cut off the motor power slowly; At the moment、 the motor can only work as normal until the temperature goes down; - Lithium battery protection: When the voltage of single battery is lower than 3.1V、 it will cut off motor power slowly and the motor will return to work after the voltage goes normal; - Over-load protection; - Blocking protection: Limits output power to 39% if propellers are blocked.
