1) 48V500W motor controller 2) Low voltage protection&speed control 3) Current limit control 4) Super low nosie star up

Function:

1)Super low noise when start: Super low noise in driving,reduce vibration of the motor,extended motor life.

2)Speed limit: The speed can be control  in any numerical which you set when running.

3)Undervoltage protection: When the batteries voltage dropping to the rate voltage's 87.5 percent, the controller can stop working to protecting the battery.

4)Temperature protection: When the controller achieve a certain temperature,it will cutting off the power output through its temperature detection module.

5)Avoid out of control: When the throttle or line out of order,the controller can prevent bicycle out of control

6)Short circuit protection: Running short circuit protect to prevent controller broken when start.

7)Current limit protection: Not only have average current but also peak current, protect MOS maximum.

8)Blockage protection: The motor plugging turn 2 seconds(time can be set),the controller protect itself automatic to prevent broken.

9)Power cut brake: Suitable for mechanical brake handle and hall brake handle,use high level and low level.

10)Cruise function: With manual and automatic two type. Stop turning the throttle 8 seconds(the time can be set) when running,the controller into cruise mode,running without throttle control.

11)E-ABS brake: Flexible E-ABS regenerative braking,braking fastly,as comfortable with the car ABS.

12)Taxiing power: When slide will be part of kinetic energy into electricity stored in a battery.

 13) A gear position indicator :  display three different speeds.

Other fuction can be designed according to the clients.
