My golf cart AC conversion is not performing as expected!

After dreaming about it for ages, I finally took the plunge and upgraded my trusty old golf cart from a DC to an AC system, aiming for that sweet increase in speed and torque. I envisioned cruising up hills and speeding along trails with ease. But, alas, reality has fallen short of my dreams.

The performance boost I was expecting just isn’t there, and it’s really bumming me out on what should be joyful weekend rides. Has anyone else tackled this conversion and hit similar roadblocks? Any advice or tips would be massively appreciated!


What helped me was diving deep into a comprehensive AC conversion kit. It felt like a hefty investment at first, but looking back, it was the best decision for my cart’s performance. Specifically, the Navitas 5K 600Amp kit was a game-changer for me. The torque was like night and day compared to before, and after fine-tuning a few settings, I was zooming past my old speed records. It sounds like this might be the missing piece in your puzzle too!

Solutions with steps

1. Comprehensive AC Conversion Kit

  • Step 1: Begin with thorough research to find a conversion kit that matches your cart model and meets your performance goals. The Navitas 5K 600Amp kit is a solid choice for a balance of speed and torque.
  • Step 2: Purchase the kit, ensuring it includes the motor, controller, wiring harness, and any other necessary components for a full conversion.
  • Step 3: Carefully follow the installation instructions provided with the kit. For some cart models, you may need to remove the batteries for better access to the motor area. Additionally, removing obstructive components like the driver’s side shock may be necessary for proper motor fitment.
  • Step 4: After installation, connect with tech support or use the dealer app to unlock the kit’s full speed capabilities and customize the settings to your liking.
  • Handy Tips: Make sure you have a set of basic mechanical tools and some electrical knowledge or a friend who does. Taking photos before disconnecting any parts can also be a lifesaver for reassembly.
  • Personal Experience: The torque improvement was instantly noticeable, completely transforming the cart’s capabilities. The installation was straightforward with patience and the right tools.
  • Expert Tip: Double-check your cart’s structural integrity and brake system to ensure they can handle the increased performance. Consider safety upgrades if necessary.

2. Upgrade to Lithium Batteries for Higher Voltage

  • Step 1: Determine the voltage and capacity requirements based on your AC system’s specifications. This will guide you in selecting a lithium battery pack that meets these needs.
  • Step 2: Choose a lithium battery pack that fits within your cart’s battery bay and meets the voltage and capacity requirements.
  • Step 3: Install the battery pack, carefully following any instructions for wiring and securing the batteries in place.
  • Step 4: Adjust your AC system’s settings to optimize performance with the new battery setup.
  • Handy Tips: Consider the weight distribution of the new batteries in your cart to maintain balance and handling.
  • Personal Experience: The switch to lithium batteries significantly reduced the overall weight and improved both speed and hill-climbing ability.
  • Expert Tip: Ensure you have a compatible charger for your lithium batteries and consider installing a Battery Management System (BMS) for safe operation.

3. Rewire Cart with Compatible Harness for AC System

  • Step 1: Obtain a wiring harness that is compatible with both your specific cart model and the chosen AC system.
  • Step 2: Carefully remove the existing wiring, documenting all connections and their locations for easy reference during reassembly.
  • Step 3: Install the new harness according to the wiring diagram, ensuring all connections are secure and correct.
  • Step 4: Test the cart thoroughly to make sure all electrical components function as expected with the new system.
  • Handy Tips: Labeling each connection as you disconnect them can save a lot of guesswork during installation of the new harness.
  • Personal Experience: While rewiring required some effort, it was essential for ensuring compatibility with the new AC system. The process went smoothly with careful planning.
  • Expert Tip: Regularly inspect and maintain your new wiring setup to prevent issues related to wear and tear or environmental exposure.
