E-Bike & E-Scooter 25A / 30A Heavy-Duty Brushless DC Motor Controller Repair & Conversion Kit –

24V / 36V / 48V Multi-Voltage Architecture (350W to 1000W Motor Support) Complete with S966 / SW900 Multi-Function LCD Digital Display & Pedal Assist Sensor (PAS) Magnet Ring

Restore performance or upgrade your electric bicycle, scooter, or tricycle with the 25A / 30A Brushless DC Motor Controller & LCD Instrument Kit. Purpose-built for 350W, 500W, 750W, and 1000W brushless hub motors, this complete drivetrain management package provides stable voltage regulation, instant throttle responsiveness, and real-time battery and speed telemetry.

Compatible with 24V, 36V, and 48V DC nominal battery platforms, the kit includes your choice of a high-visibility SW900 LCD Display or a full-color S966 LCD Dashboard Panel, along with an 8-magnet Pedal Assist Sensor (PAS) for smooth pedal-assist integration.

⚠️ System Compatibility & Voltage Configuration

IMPORTANT FITMENT GUIDELINES:

• Multi-Voltage System Compatibility: Operates seamlessly on 24V, 36V, and 48V DC battery systems (automatically detects battery voltage upon initial startup).

• Current & Wattage Handling: 25A and 30A current limits safely support 350W to 1000W brushless motors without thermal overloading.

• Display Protocol: Uses standard UART communication protocols between the controller and the LCD instrument panel for accurate speed and error code readouts.

🚀 Key High-Performance Features

• Multi-Voltage Support (24V / 36V / 48V): Adapts automatically to your battery pack, making it ideal for custom conversions, repairs, and voltage upgrades.

• S966 / SW900 Digital LCD Dashboard: Displays real-time speed, battery capacity levels, trip odometer, PAS assistance level (0–5), wattage consumption, and diagnostic trouble codes.

• Includes Pedal Assist Sensor (PAS): Enhances motor responsiveness to pedaling cadence for a smooth, natural riding feel.

• Compact Heat-Dissipating Casing: Durable aluminum alloy housing protects internal power MOSFETs during sustained climbs and high-speed runs.

• Complete Wiring Suite: Pre-wired leads for battery (+/-), motor phase wires, Hall sensors, throttle signal, brake cut-off switches, headlight output, and PAS sensor input.
