Eco Power AC Conversion Kit Guide

Is your golf cart feeling sluggish, struggling on hills, or just not keeping up with the performance you want? You’re not alone—most stock golf carts are built for basic cruising, not for speed, power, or heavy loads. But here’s the good news: upgrading your ride doesn’t have to be complicated.

The new  EB Power AC Conversion Kit is the ultimate performance upgrade for golf cart owners who want more—more speed, more torque, and more control. Whether you’re after smoother acceleration for everyday rides or raw power to tackle steep hills and heavy loads, this kit transforms your cart from average to amazing in just a few hours.

What is the EB Power AC Conversion Kit?

The EB Power AC Conversion Kit is an all-in-one performance upgrade designed to replace your golf cart’s standard DC system with a powerful AC motor and controller. Unlike stock setups that limit your speed and torque, this kit unlocks the full potential of your cart—delivering faster top speeds, stronger hill-climbing ability, and smoother throttle response.

What makes EB Power different is its complete package design. Instead of piecing together multiple parts or chasing down missing components, you get everything needed in one box: pre-assembled controller plate, AC motor, wiring harness, solenoid, cables, and hardware. That means no guesswork, no hidden extras—just a straightforward upgrade you can install with confidence.

Whether you’re upgrading for fun, function, or both, the EB Power AC Conversion Kit gives you the freedom to customize your ride. From mild cruising setups to maximum power builds, it’s the go-to solution for golf cart owners who want reliability, simplicity, and unmatched performance.

Performance Options to Match Your Driving Style

Not every golf cart driver has the same needs. Some want a simple boost for smoother rides, while others want maximum power for hauling, hills, or adrenaline-pumping speed. The EB Power AC Conversion Kit comes in three performance setups, so you can choose the one that fits your lifestyle.

Each option is designed to give you the right balance of speed, power, and drivability. Whether you just want your cart to feel less sluggish or you’re looking to push it to the limits, EB Power delivers a setup that makes your cart perform the way you’ve always wanted.

Compatible Golf Carts

The EB Power AC Conversion Kit was designed around the drivetrain geometry and electrical architecture of the industry’s most common carts. It uses a 19-spline or 10-spline AC motor shaft depending on the cart, heavy-duty wiring, and controller plates engineered for modern Yamaha, EZGO, and Club Car chassis.

Fits Most:

• Yamaha – Compatible with most Yamaha Drive and Drive2 models. Yamaha’s standardized motor mounting flange and rear axle setup align cleanly with the EB Power AC motor, making installation straightforward.
  
  

• EZGO TXT 1994 and newer – Works seamlessly with carts that use the 19-spline input shaft. The TXT frame provides adequate clearance for the 4kW and 5kW motors, as well as the pre-assembled controller plate.
  
  

• Club Car DS – Compatible with all model years. The EB Power AC Conversion Kit aligns with the DS motor spline count and controller setup, ensuring reliable installation across the entire DS lineup.
  
  

• Club Car Precedent/Onward/Tempo (2004 and newer) – These models feature the correct spline count and updated controller bays, providing secure fitment and easy integration with the AC system.

Not Compatible With:

• EZGO Marathon (pre-1994) – These carts use a different frame and motor mount pattern, with smaller compartments that cannot accommodate the 19-spline AC motor or the larger controller plate.
  
  

• EZGO RXV – Already comes from the factory with an OEM-integrated AC drivetrain that uses a proprietary controller and wiring harness. Replacing it with the EB Power kit would require bypassing the factory CAN-bus system, which is not supported.
  
  

What’s Included in the EB Power Kit?

When you order the EB Power AC Conversion Kit, you’re not just getting a motor and controller—you’re getting a complete, ready-to-install upgrade. Everything you need comes in one box, with no guesswork and no missing pieces.

Premium Drivability & Smart Installation

Upgrading to the EB Power AC Conversion Kit isn’t just about raw numbers—it’s about transforming the way your cart feels on every ride. From throttle response to hill-climbing confidence, the difference is immediate.

Premium Drivability

• Smooth, Consistent Acceleration – No jerks, no lag—just clean power delivery that makes every drive effortless.
  

• Customizable Driving Modes – Three user-friendly power modes let you fine-tune performance for different situations: a safe mode for kids or guests, a balanced everyday mode, and a high-performance mode when you want full power.
  

• Confident Handling – With torque delivered more efficiently, your cart feels stable whether you’re cruising with two passengers or hauling a full load.
  

Smart Installation

• Pre-Assembled Controller Plate – Major components come mounted and wired, cutting installation time dramatically.
  

• Clearly Labeled Harness & Cables – Every connection is tagged, making it simple for first-time installers and quick for experienced technicians.
  

• Fits Most Stock Frames – Designed to drop into Yamaha, EZGO, and Club Car models without custom fabrication.
  

• Technician-Tested Adjustments – On certain Yamaha models, a 6" lift kit may be needed for clearance when using the 5kW motor. In some installs, motors may be secured using 3 of 6 bolts (a manufacturer-approved method that remains safe and reliable).
  

• Reasonable Install Time – Most installs take about 4–6 hours, depending on the cart model and accessories.

Eco Battery Integration: The Perfect Pair

The EB Power AC Conversion Kit is powerful on its own—but when paired with an Eco Battery lithium pack, the upgrade goes from great to unbeatable. These two systems were designed to work hand-in-hand, giving you maximum efficiency, extended battery life, and peak performance.

Why It Works So Well Together

• Seamless Communication – Eco Battery’s Gen 2 and Gen 3 lithium systems use a proprietary Battery Management System (BMS) that integrates directly with the EB Power controller. This means your motor and battery “speak the same language” for smoother power delivery and fewer system errors.
  

• Maximum Efficiency – Lithium packs deliver steady voltage throughout the discharge cycle, so your cart keeps full performance until the very last mile—no sluggish fade-out like with lead-acid.
  

• Longer Battery Life – Because the BMS regulates temperature, charging, and discharge cycles, your Eco Battery lasts longer while maintaining peak output.
  

• Lightweight Power – Dropping 300+ pounds of lead-acid weight means faster acceleration, longer range, and less strain on your motor and drivetrain.
  

The Real-World Advantage

Pairing the EB Power kit with an Eco Battery lithium pack results in:

• Faster charging times
  

• Increased daily driving range
  

• Stronger hill-climbing ability
  

• Longer overall system lifespan
  

When combined, you’re not just upgrading your cart—you’re building a next-generation electric system backed by the most knowledgeable support team in the business.

Performance Insights (Provided by Extreme Kartz Technician)

One of the standout features of the EB Power AC Conversion Kit is how straightforward the installation is compared to other systems. Thanks to its thoughtful design and pre-assembled components, both DIY enthusiasts and professional technicians can complete the install with confidence.

Technician Insights on Installation

Cart-Specific Notes

• Yamaha and Club Car DS Models – When installing the 5kW motor, a 6-inch lift kit may be required to provide adequate clearance.
  

• Motor Mounting – In some cases, technicians secure the motor using 3 of the 6 available bolts. This configuration is manufacturer-approved and has been proven t be secure, even under heavy load.
  

• Repositioning Flexibility – Depending on the cart frame, slight repositioning of the motor may be necessary, but the EB Power kit is designed to accommodate these adjustments without compromising safety or performance.
