Alltrax XCT48400IQ — Club Car 48V 400A Controller

Programmable XCT controller for compatible 48V Club Car IQ or Precedent i2/Excel DC regen systems, with the correct application setup.

Select the original electrical system

Choose IQ / Precedent IQ or Precedent i2 / Excel above. Your selection is recorded on the order. These systems must not be treated as interchangeable just because the connector fits. Verify the original controller label and throttle; body style, model year and battery count alone are not enough.

Not sure? Contact Winnie's through our contact page before buying and send your cart model/year, original controller label/connectors, battery-pack voltage and motor information. The unconfigured option cannot be purchased. For aftermarket motors or modified wiring, confirm the complete application before ordering.

Features and installation

USB programming with Alltrax Toolkit, motor-specific control settings, sealed electronics and integrated heat sink. Cooling fan optional on the 400A model. The amperage is a controller current class, not an unlimited continuous-current rating.

Not for series, Regen I/II, factory AC or unverified factory-lithium systems. Program for the exact motor and verify battery capability, throttle, cables and contactor ratings. Application-specific mounting or installation parts may be required and are not assumed included.

Controller only; motor, power cable kit and solenoid are not included. Representative XCT family photo.

Base model: XCT48400IQ
D&D family reference: XCT-400-IQ; specify the selected IQ or i2/Excel system.

48V

Electric

48V IQ-family DC regen only. Verify original controller and motor. IQ and i2/Excel require the correct throttle/controller configuration; similar connectors alone do not establish compatibility. Not series, Regen I/II or factory AC; factory-lithium integration needs confirmation. Motor-specific programming and adequate battery/cable/contactor ratings required.

Cart details are saved on this device only. Do not enter personal information here. Changing carts clears the previous configuration.

Unknown details will not be treated as confirmed.

Not sure which cart you have?

Use the vehicle label and manufacturer guidance to identify your cart. Body panels, batteries and drivetrains can be changed; a model name alone does not prove part compatibility.

Club Car

Club Car: check the barcode label below the passenger-side cup holder or above the pedals. The model letters are followed by the model-year and production-week digits. Use the manufacturer directory to confirm the prefix.

Open manufacturer identification guide

E-Z-GO

E-Z-GO: for models purchased before 2023, the manufacturer points to the steering column or below the driver-side seat. Location varies by model. Photograph the complete label, including the manufacturer code.

Yamaha

Yamaha: check under the seat at the floorboard/motor compartment, on the frame under the rear bumper, or beneath the driver-side glove box. Use the full identification label, not just the body appearance.

Park securely, set the parking brake and remove the key before looking for labels. Do not touch electrical terminals or work underneath an unsupported vehicle.
