Controller for Electric Bicycles & Electric Motorcycle.

We are among the precursors who are majoring in the electric vehicle(EV) project in china,
Now we produce all types of controllers and converter for electric vehicles (EV) and electric boats(EB).
Our electronic pulse-width modulated (PWM) controllers that includes low voltage battery protection, peak amperage protection,maximum speed protection,and stall protection.
we have some different box configuration,and if you have adequate quantity demands,we can offer the box configuration according to your requirement.

8,Photo 100-1132;Rises voltage/Falls voltage the DC-DC converter.
Input output voltage 12-72V, output 5-300W, the user may choose
voluntarily. Has short-circuits, has flowed and so on the conventional
protection, has low characteristic and so on ripple, high efficiency.
