Universal eBike Motor Controller – 36V–84V, 20A–25A, 350W–500W

Upgrade or replace a compatible electric bike or scooter controller with this universal brushless motor controller. Designed for a range of listed battery voltages and current ratings, it supports common e-bike functions such as throttle control, pedal assist, electronic braking, cruise control, reverse, and three-speed selection, depending on the controller version and connected accessories.

With nine MOSFETs listed by the supplier and support for compatible Hall-sensor or sensorless motor configurations, this controller is intended for DIY repairs and replacement projects where the electrical specifications and wiring match your existing system.

Please verify the exact controller version before ordering: the supplier describes the product as both a sine-wave controller and a square-wave controller. Confirm the waveform type, voltage, current rating, and connector layout for your selected model.

Key Features

Wide Voltage Selection: The supplier lists 36V, 42V, 48V, 52V, 60V, 72V, and 84V systems. Confirm the specific version and supported battery voltage before use.
Multiple Current Options: Advertised at 20A, 21A, 23A, and 25A, depending on the variant.
350W–500W Motor Applications: Listed for compatible brushless motor systems in this power range.
Hall-Sensor Support: Hall connections are provided for compatible motors; some sensorless motors may not require Hall wiring.
Throttle Control: Supports a compatible electric throttle.
Pedal Assist (PAS): Connection for compatible pedal-assist sensors.
Brake Inputs: Supports listed low-level and high-level brake signals, subject to wiring compatibility.
Additional Functions: Listed features include reverse, cruise control, three-speed selection, electric door lock, and anti-theft signal connections.
Self-Learning Function: Intelligent recognition wires are listed for motor direction identification on compatible versions.
Broad Motor Compatibility: The supplier mentions phase-angle options of 60° and 120° and a special configuration for differential motors. Confirm suitability for your motor before purchasing.

Check Compatibility Before Ordering

Controller compatibility depends on more than the battery voltage. Confirm these details before installing or replacing your controller:

Battery voltage: Match the controller to the battery's nominal voltage and fully charged voltage.
Current rating: Ensure the controller's current limit is compatible with the battery's BMS, wiring, connectors, and motor.
Motor type: Check the motor phase wires, Hall sensor configuration, and phase angle.
Waveform: Confirm whether your selected version is sine wave or square wave.
Throttle and display: Verify connector pinouts, signal voltage, and display compatibility.
Brake and accessory signals: Check whether your brake sensors and optional features use low-level or high-level signals.

The supplier's stated 12–96V throttle range should not be interpreted as permission to apply that voltage directly to every throttle wire. Follow the controller wiring diagram and the throttle manufacturer's specifications.

Self-Learning Wire Instructions

The supplier describes a self-learning procedure for identifying motor direction. Because wiring layouts can vary, use only the instructions supplied for the exact controller version.

Disconnect battery power before connecting or changing wires.
Secure the driven wheel so it cannot contact the ground or nearby objects.
Connect the motor phase wires and Hall wires according to the manufacturer's diagram.
Follow the model-specific self-learning procedure and check the wheel direction at low speed.
Disconnect the self-learning wires after the procedure if instructed by the manufacturer.

Do not connect wires based on color alone. Incorrect wiring can damage the controller, motor, battery, or connected electronics.

Frequently Asked Questions

Does this controller support 48V and 60V batteries?

Those voltages are listed by the supplier. Verify the exact controller version and its maximum input voltage before connecting your battery.

Can I choose a 20A, 21A, 23A, or 25A version?

These current ratings appear in the listing. Confirm the available options and whether the stated rating is continuous or peak current.

Is this a sine-wave or square-wave controller?

The supplier describes both types. Confirm the actual waveform for the specific version before purchasing, particularly if you are replacing an existing controller.

Does it support reverse and cruise control?

These functions are listed, but operation depends on the controller version and compatible switches or accessories.

Does it include a battery or throttle?

The supplied information describes the controller and its wiring functions but does not confirm all included accessories. Verify package contents with the seller.
