is it worth upgrading my 2007 EZGO TXT from 36v to 48v?

I’ve got a 2007 EZGO TXT Series 36v cart, and while it’s been reliable, it just doesn’t have the oomph I need, especially on hills and with extra passengers. I’m seriously considering upgrading to a 48v system for more power. Has anyone here done this? How complex and costly is it? Any advice would be greatly appreciated!


I upgraded my 2008 EZGO to a 48v system, and it’s like a whole new cart! More power, better hill climbing, and overall improved performance. It’s a bit of a project, but if you’re handy and have some basic electrical knowledge, it’s definitely doable and worth it.

  • Cart struggles on hills or with extra weight.
  • Noticeable lack of power compared to other carts.
  • Desire for increased speed and torque.

Possible Causes

  • The current 36v system may not provide enough power for desired performance.
  • Components like the controller, solenoid, or motor may be limiting the cart’s capabilities.

Detailed Solutions that Worked

1. Upgrade to 48v System

What I Did: Upgraded my entire cart to a 48v system, including batteries and charger.

Outcome: The cart now has significantly more power and speed.

Personal Experience: The upgrade was a game-changer. Hills are no longer an issue, and the cart feels more responsive.

Detailed Steps:

  1. Research and Purchase: Start by researching compatible 48v controllers, solenoids, batteries, and chargers. Look for parts that are specifically designed for your EZGO model.
  2. Battery Replacement: Safely remove the old 36v batteries and install the new 48v ones. Ensure proper alignment and secure connections.
  3. Controller and Solenoid Installation: Replace the old controller and solenoid with the new 48v compatible ones. Pay close attention to wiring diagrams to ensure correct installation.
  4. Testing and Troubleshooting: After installation, test the cart thoroughly. Check for any unusual noises or behaviors and troubleshoot as necessary.

Handy Tips:

  • Label all wires during disassembly to make reassembly easier.
  • Charge the new batteries fully before the first use.

Unique Info:

  • Consider the weight difference with new batteries, as it may affect the cart’s handling.

2. Controller and Solenoid Upgrade

What I Did: Replaced the existing controller and solenoid with higher capacity ones.

Outcome: Improved torque and overall performance.

Personal Experience: This upgrade alone made a noticeable difference, especially in torque.

Detailed Steps:

  1. Selection of Parts: Choose a controller and solenoid that can handle higher amperage for better performance.
  2. Installation: Carefully remove the old controller and solenoid. Install the new ones, ensuring all connections are secure.
  3. Adjustments: Make necessary adjustments to the controller settings to optimize performance.

Handy Tips:

  • Use dielectric grease on connections to prevent corrosion.

Unique Info:

  • Upgrading the solenoid to a heavy-duty version can handle increased electrical demands.

3. Motor Inspection and Cable Upgrade

What I Did: Inspected the motor and upgraded all cables to 4 awg.

Outcome: Enhanced electrical efficiency and motor response.

Personal Experience: The motor was in good condition, and the cable upgrade reduced resistance.

Detailed Steps:

  1. Motor Check: Inspect the motor for wear or damage. Look for signs of overheating or worn brushes.
  2. Cable Upgrade: Replace thinner cables with 4 awg cables for better conductivity and reduced heat buildup.
  3. Connection Check: Ensure all connections are tight and secure.

Handy Tips:

  • Regularly clean and inspect the motor compartment to prevent dust buildup.

Unique Info:

  • Upgrading cables can also reduce the risk of electrical fires.

4. AC Motor Conversion

What I Did: Converted the cart to an AC motor system.

Outcome: Significantly improved efficiency and smoother operation.

Personal Experience: The conversion was more complex but worth the effort for the performance gain.

Detailed Steps:

  1. AC Motor Kit: Purchase a kit that includes an AC motor and compatible controller.
  2. Installation: Remove the DC motor and install the AC motor. Follow the kit’s instructions for wiring and controller setup.
  3. Testing: Test the cart extensively, paying attention to acceleration, braking, and handling.

Handy Tips:

  • Ensure the new motor’s mounting aligns with the existing frame.

Unique Info:

  • AC motors typically offer better torque and efficiency than DC motors.
