Synchronous rectification, ultra low drop, fast PWM to achieve very high efficiency.Intelligence with powerful microprocessor.Specially designed for electric bicycle and scooter.This programmable brushless motor controller also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily. In most cases, Powerful microprocessor brings in comprehensive and precise control to BLDC motor controllers. BLDC motor speed controller uses high power MOSFET, PWM to achieve efficiency 99%. Motor speed controller can work with relative small battery, but provide good acceleration and hill climbing. Ebike brushless motor controller outputs high taking off current, and strictly limit battery current.
