Details:

The battery type can be Lithium battery, Lead Acid. Automatically recognize the motor phase angle and right spin direction. Product Feature. It can be suitable to three - wire throttle brushless DC Hub Motor under 800W.

When the direction is right, disconnect Self-Study wires, finished!, Start silently, balanced and constant power out-put, Mature Production technical of Controller authentic quality. When the motor phase is failure, controller will protect it, avoid burned, and battery at same time. It can be conducted by the Self-Study wires. Over-heat protection, the controller will cut power when temperature is over top, and restart if normal.

Intelligent management of battery system, the controller will reasonable control discharge, low- voltage protection function to extend life. Operation Method: Firstly make sure the battery, Key lock, Motor, throttle are well connected, and also connected two Self-Study wires. If the motor sensors are broken, controller will operate to None-Hall mode. New List Item.

Then open the battery power and key lock, motor will spin, if spinning direction is correct, please disconnect two Self-study wires, then study accomplished. This controller has no fixed speed cruise function. Single voltage Electric Bicycle E-bike Scooter Brushless DC Motor Speed Controller.
