Status LEDs and Flashing Patterns
The controller is equipped with 3 LEDs. A Green Power LED, a Red/Green Status LED,
and a Yellow Communication LED.
After the controller is powered on, the Power LED will tun on, indicating that the controller

Measured and Calculated Amps
The controller includes Amps sensor in line with the motor terminals. Motor Amps are
therefore measured with precision. Battery Amps is estimated using the formula Battery
Amps = Motor Amps * PWM. This formula produces accurate results as long as the mo-
