Controller Replacement
Match battery voltage, motor, current, sensors, wiring and connector pinout.
Electrical Parts
Controllers, converters, switching, display, wiring and related components for supported electric three-wheeler configurations.
Product Overview
Electrical components require exact matching
Voltage alone is not enough to identify an electrical part. Controller current, motor phase or sensor arrangement, connector pinout, communication, mounting and vehicle wiring can differ.
Never connect an unidentified part to a battery system. Wrong polarity, rating or pinout can damage the component, wiring, controller or battery and can create fire or electric-arc risk.

Helpful Answers
Frequently Asked Questions
Can I install a higher-current controller for more speed?
Changing controller current can overload the motor, battery, BMS, wiring, connectors and drivetrain. It requires a complete engineering review.
Why are connector photos not enough?
Identical-looking connectors can use different pin assignments and electrical functions.
What details should I send?
Send the vehicle and old part labels, full photos, connector close-ups, wire colors, dimensions and fault symptoms.
