12 volt / 36V/48V 500W/800W/1000W Electric Scooter Bike Brushless cd Motor speed Controller

First look at your electric bikebattery voltage levels, corresponding to the selected voltage controller, look at the size of the current controller previously used, such as the current is 16A-18A 350W controller, 22A-24A controller is 450W, 28A -30A controller is 500W, 31A-33A is 600W controller, 33A-35A is 800W controller, 36A-38A is the 1000W controller, 40A-43A is the 1200W controller, 50A is about 2000W controller . Such selection controller, if the original car is 350W controllers we recommend the use of bigger, so you can take advantage of the highest motor speed and power.

BRUSHLESS DC MOTOR CONTROLLERS' FEATURES Using the intelligent MPU.
Low energy consumption in High-speed, with synchronous rectification PWM circuit.
Battery current limit function can prolong the lifespan of battery sets.
Big starting current provide high starting speed.
Superior anti-interference and anti-shock performance.
Status LED indicates different fault information, it help the users to diagnostics & maintain the controller conveniently.
With battery protection function ,it protect against the low voltage &over voltage by reducing or cutting off the battery current output.
With thermal protection function, this thermal protection &compensation circuit provides constant current limit durng iunder/over temperature condition ,so it can protect the controller and battery well.
Compatible with the 60°/120°hall sensor in both.
Throttle protection function disable the controller if throttle wires become open, also can prevent the controller operation if the electricity key is turned on while throttle is applied (For optional).
Manual cruise/auto cruise function are available(For optional).
Auto-matching with all kinds of motors.
Configurable soft/quick start mode.
Online/offline updating function available.
BRUSHLESS DC MOTOR CONTROLLERS' REGULAR FUNCTIONS Configurable over/under voltage protection function offers real-time battery current monitoring (For optional)
Single periodic current adjustment provide over voltage protecting in microsecond rates.
With thermal sensor to detecting any thermal information.
Configurable EABS brake system effect by strong/weak braking signal (For optional)
Safety reversing function, reversing speed can be set by 30% to 50% of the forwarding speed
Providing +5V powering to hall sensor with over current protecting,
Configurable Forwarding, Neutral and Reversing operations(For optional)
3 wires access of speed governing, additional supplying +5V power source
5 wires access of hall sensor connector, no hall sensor application is available for optional
Real-time battery current monitoring system make sure the output current will not excess the maximum battery working current.
