Replaces EZGO Curtis 1236AC Controllers.

Enhance the performance of your 72-volt EZGO TXT/S4/L6 with this 600A controller, perfect for vehicles with lifted configurations and large tires, particularly in hilly terrain. It's also ideal for those aiming to reach speeds of up to 25 MPH on standard 18" tires.

Experience real-time customization of your driving experience with the On-The-Fly Programmer. Easily adjust top speed, braking, acceleration, and battery driving range with a simple turn of the knob. Additionally, take advantage of the newly integrated Bluetooth feature to transform your smartphone into a vehicle instrument panel. Through the dashboard app, vehicle owners can remotely lock their vehicle, monitor usage and performance, and even notify their dealers with diagnostic information.


    • Fit EZ-GO with Curtis 1236AC Controllers. (Cart should also have an AC motor)

Pre Purchase Checklist:

    • Cart must have a Curtis 1236AC Controller. 
    • Heavy duty solenoid (required for controllers 440 amps or higher)
    • If you have a Lithium battery check your battery discharge specification to ensure the battery can handle the amperage Navitas controllers call for. Insufficient amperage ratings will call for the controller amperage to be turned down. The 440 amp controller should have a 400 amp output battery. 600 amp controllers should have a 500 -600 amp output battery. 
    • Carts with lead acid batteries should have heavy duty battery cables. 4 Gauge or bigger cables.
