FAQs

What amperage controller is ideal for a modified E-Z-Go TXT 48V?

It depends on how your cart is set up. If your cart is stock and used on flat ground, the 300A is the right fit. If you have bigger tires, a lift kit, or ride on hills regularly, go with the 400A or 500A for better power and speed.

What is the price of the Alltrax XCT Regen 300A golf cart controller?

Golf Cart Gears has the Alltrax XCT Regen 300A priced at just $998.99 — originally $1,288.70.

What is the difference between the 300A, 400A, and 500A models?

The 300A gives you about 5% more torque than stock and tops out around 14 mph — great for everyday riding. The 400A pushes 20% more torque and reaches 20–22 mph, ideal for modified carts. The 500A gives 30% more torque and handles the heaviest loads and full performance builds.

What comes in the box with the Alltrax XCT Regen 300A Golf Cart Controller?

The box includes the Alltrax XCT Regen 300A controller and fuses. The universal mounting adapter and fan assembly are sold separately. Make sure to order your solenoid upgrade before install day so everything is ready to go.

Do I need to buy anything else before installing this controller?

Yes — two things. The universal mounting adapter (sold separately) makes installation cleaner and faster. More importantly, your stock solenoids must be replaced before you install this controller. Stock solenoids are too weak and will fail if used with the Alltrax XCT.

Why do I need to replace my solenoids before installing?

Your stock EZGO TXT 48V solenoids are not rated for the higher current the Alltrax XCT pushes. If you run this controller on stock solenoids, they will burn out and can damage the controller too. You need high-current-capacity solenoids, each with a diode and pre-charge resistor installed. Browse our golf cart solenoid section for the right fit.

What is the warranty on the Alltrax XCT Regen 300A Golf Cart Controller?

The Alltrax XCT Regen 300A is backed by the manufacturer warranty covering defects in parts and workmanship. If you have a warranty issue, call us at 1-888-385-4708 and we will sort it out fast. We make returns and replacements easy.

Is this Alltrax XCT Regen 300A Golf Cart Controller compatible with the EZGO TXT 48V golf cart?

This controller fits E-Z-Go TXT 48V carts from 2008 to present with a Regen (regenerative) motor. It does not fit Series motor carts, 36V models, or any non-EZGO TXT 48V cart. Not sure about your motor type? Call us at 1-888-385-4708 and we will confirm it for you.

How does a golf cart controller improve acceleration and top speed?

The stock Curtis controller on your TXT 48V is tuned conservatively—it limits current flow to protect older electronics. The Alltrax XCT delivers more current more precisely, giving you faster throttle response off the line and a higher top speed in go-fast mode. The difference is noticeable from your very first ride.

How does a regen controller improve battery life?

Every time you lift your foot off the pedal, the Regen motor sends power back into your battery pack instead of wasting it as heat. The Alltrax XCT manages this process more efficiently than the stock controller. You can even adjust how strong the regenerative braking is through the USB programming port to maximize energy recovery on every ride.
