I just got a 2010 EZGO TXT 48v, and it’s painfully slow. I’m lagging behind all the other carts in my neighborhood. I’m aiming for at least 20mph or more. Does anyone have any tried-and-true solutions? I’m eager to catch up with the rest!
Response
A few months ago I had to deal with this same problem with my EZGO TXT. Upgrading to a 500 amp controller provided me with the performance boost I needed. It might be a good starting point for you too.

Symptoms
- The golf cart is significantly slower than others, struggling to keep up.
- Lacks the power to reach desired speeds, even on flat terrain.
Possible Causes
- Inadequate controller limiting the cart’s speed and power.
- Smaller tires reducing the cart’s speed potential.
- Insufficient battery voltage not providing enough power.
- The motor is not capable of higher speeds.
Solutions that Worked
- Controller Upgrade (500 amp)
- What I Did: Upgraded to a higher amperage controller for increased power.
- Outcome: The cart’s speed significantly improved, reaching over 20mph.
- Personal Experience: The upgrade was straightforward, and the speed increase was immediately noticeable.
- Steps:
- Research and purchase a compatible 500 amp controller, ensuring it matches your cart’s specifications.
- Disconnect the power source to ensure safety during installation.
- Carefully remove the old controller, noting the connection points for an easier installation of the new one.
- Install the new controller, double-checking all connections for accuracy.
- Reconnect the power and conduct a test drive to assess the performance improvement.
- Expert Tip: After installation, monitor the controller’s temperature during the initial runs. Overheating can indicate improper installation or compatibility issues.
- Larger Tires (23″)
- What I Did: Replaced standard tires with larger 23″ tires.
- Outcome: Increased the top speed due to the larger tire circumference.
- Personal Experience: The cart not only went faster but also had a better appearance.
- Steps:
- Select the right size tires for your cart, considering both diameter and width.
- Use appropriate tools to remove the old tires and mount the new ones securely.
- Ensure proper tire inflation and alignment for optimal performance.
- Test drive to feel the difference in speed and handling.
- Expert Tip: Larger tires can change the cart’s center of gravity. Be cautious during the first few rides as the handling may feel different.
- Battery Pack Voltage Increase
- What I Did: Upgraded the battery pack to a higher voltage.
- Outcome: Provided more power to the motor, increasing speed.
- Personal Experience: This was a more involved upgrade but worth the effort for the speed gain.
- Steps:
- Research and select a higher voltage battery pack that is compatible with your cart.
- Safely disconnect and remove the old battery pack, taking care to dispose of it properly.
- Install the new battery pack, ensuring all connections are secure and properly configured.
- Test the cart for enhanced performance, paying attention to any unusual sounds or behaviors.
- Expert Tip: Consider the weight of the new battery pack. Heavier batteries can affect the cart’s balance and handling.
- Motor Replacement
- What I Did: Replaced the existing motor with a higher performance one.
- Outcome: The cart achieved higher speeds with the new motor.
- Personal Experience: The motor swap was a bit challenging but paid off in terms of speed.
- Steps:
- Choose a high-performance motor that is compatible with your cart’s model and controller.
- Disconnect the power source and carefully remove the old motor.
- Install the new motor, ensuring all connections are correct and secure.
- Test the cart to confirm the speed improvement and listen for any unusual noises.
- Expert Tip: After installing the new motor, check the alignment and tension of the belts or chains, if applicable. Improper alignment can lead to inefficiencies and wear.
