Review on Controller DC10 55V Forward Brake Reverse Adjustable Potentiometer by Pop Henneghan

This controller came as a surprise to me. The controls included a forward/reverse switch with a center off position, a potentiometer to control motor speed, and an LED display. I wasn't sure what the LED would indicate as it wasn't connected to any feedback from the motor shaft. It appears that the display shows the percentage of drive to the motor. It's an electrical number and doesn't actually indicate the RPM of the engine. Zero percent on the display means the motor is off, 100% means the motor is getting full power from the controller. A very functional product and a good buy for small engines. highlighted.
