The Eco Battery 51V Universal Bundle is a complete lead-acid-to-lithium conversion kit for 48V golf carts that do not have a factory-specific lithium fitment. Built on Eco Battery's GEN3 LiFePO4 platform, every bundle ships with the battery, a matched CAN lithium charger, a 12V converter for your accessories, a plug-and-play state-of-charge meter, a 110V quick-connect charge port, mounting hardware, and a remote wake-up button. No cart-side programming and no Tech Tool are required, which is what makes this a true universal conversion.

If your cart still runs on a heavy bank of lead-acid batteries, this bundle replaces all of them with a single sealed lithium pack and everything needed to wire it up. You get more usable range, faster charging, a large weight reduction, and power that stays consistent as the pack drains instead of fading the way lead-acid does. It is designed for owners upgrading golf carts, neighborhood vehicles, and utility or hunting carts that do not have a cart-specific Eco Battery kit.

Because the battery, charger, and meter communicate over Eco Battery's CAN link, the components recognize each other on their own. The auto-baud meter self-configures and there is no cart-side software to flash, so the install stays approachable for an owner comfortable with basic hand tools while still leaving room for a clean custom build. You choose the capacity that matches how far you drive, and a heated version is available on every size for use in freezing climates.

The result is a lighter, lower-maintenance cart with dependable daily range, real-time monitoring through the EB Power app, and Eco Battery's US-based support standing behind it.

Key Features

• Grade-A LiFePO4 cells: Stable lithium iron phosphate chemistry that holds voltage through most of the charge. The cart keeps its power late in the day instead of slowing down like an aging lead-acid pack.
  
  
• Proprietary Eco BMS with CAN communication: The battery management system monitors cells, temperature, and current, and talks to the charger and meter. Layered safety during charge, use, and storage, with enough discharge headroom to support performance controller upgrades.
  
  
• Power Save storage mode: Built-in automatic and adjustable power-off timers. The pack protects itself during long storage, and the included remote button wakes it when you are ready to drive.
  
  
• EB Power app monitoring: Bluetooth connection to your phone. Check state of charge, run diagnostics, and keep firmware current without extra tools.
  
  
• Powder-coated steel case, IP67-rated: Sealed metal housing rated for water and weather resistance. Handles rough terrain, wash-downs, and outdoor use without the corrosion of a lead-acid bank.
  
  
• CAN charger and auto-baud meter: Matched charging and display components that configure themselves. Plug-and-play setup with no programming, which is what keeps this bundle universal across carts.
  
  
• Included 12V converter: DC-DC converter with a wide 40 - 90V input. Keeps your lights, horn, and 12V accessories working after the lead-acid bank is removed.
  
  
• Self-heating option: Available on every capacity. The heated pack warms itself so it can charge safely down to -4°F for year-round use in cold climates.

Fitment & Range

This is the bundle to choose when your cart does not have an Eco Battery model-specific kit. It is a direct lead-acid-to-lithium swap that uses your existing tray area, with mounting hardware included. Installation is DIY and, depending on the cart, may involve minor drilling, custom mounting, or light fabrication to seat the pack securely.

Commonly converted with this bundle:

• Star EV
• Evolution (lead-acid / earlier models)
• Bintelli
• Advanced EV
• Denago
• Tomberlin
• Cushman
• GEM
• Bad Boy Buggy
• HDK / Coleman and other 48V utility and hunting carts

Choose the Right Eco Battery Capacity

Estimated range is based on a typical stock 48V golf cart. Actual mileage varies depending on cart weight, passenger load, terrain, speed, tire size, weather, accessories, and driving conditions.

When to choose the Skinny vs. the Thru-Hole

The Skinny and Thru-Hole batteries provide the same 105Ah capacity, performance, and estimated 35 - 45-mile range. Choose based on the available space and mounting configuration:

• Choose the 105Ah Skinny when the battery compartment is long and narrow. Its 22-inch design works well in carts or conversion trays with limited width.
• Choose the 105Ah Thru-Hole when you need a shorter, more compact battery. Its patented center mounting tunnel allows a rod or J-hook to pass through the battery for a secure installation, which is especially useful in compatible Club Car trays.

For a universal installation, neither option is automatically better. Measure the battery compartment and select the shape that fits most naturally with the least modification. Always confirm dimensions, cable clearance, and mounting points before ordering.

What's in the Kit

Every capacity ships as a complete bundle. The support components are the same across all four; only the battery and the mounting hardware change.

• 51V GEN3 LiFePO4 battery: 60Ah (A-051060-05), 105Ah Skinny (A-051105-03), 105Ah Thru-Hole (A-051105-01), or 160Ah (A-051160-06)
  
  
• 38V–51V 15A CAN charger (A-1055):  lithium-profile charger matched to the pack
  
  
• DC-DC 12V converter, 40V - 90V input (A-1272): powers lights, horn, and 12V accessories
  
  
• CAN LCD state-of-charge meter, auto-baud (A-3109): plug-and-play, self-configuring
  
  
• 110V quick-connect charge port (A-4022):  standard round receptacle used across most conversion carts
  
  
• Battery mounting hardware: Universal Center Rod Kit (A-8006) on the 105Ah Thru-Hole; 5/16in hardware (A-8003) on the 60Ah, 105Ah Skinny, and 160Ah
  
  
• Remote battery wake-up button (A-4220): wakes the pack from Power Save sleep mode

Specifications

Shared bundle components across all capacities: 38V-51V 15A CAN charger (A-1055), DC-DC 12V converter with 40–90V input (A-1272), CAN LCD auto-baud SOC meter (A-3109), 110V quick-connect charge port (A-4022), and remote wake-up button (A-4220).

Installation

This is a DIY-friendly conversion, but every cart has its own quirks, especially the off-brand and older carts this bundle is made for. Read this before you start.

The basic sequence:

• Disconnect and remove the full lead-acid battery bank.
• Seat the lithium pack in the tray and secure it with the included mounting hardware. Minor drilling or a custom bracket may be needed on some carts.
• Connect the main positive and negative leads to the cart.
• Install the 12V converter (A-1272) so your lights, horn, and accessories keep working.
• Wire in the 110V charge port (A-4022) and the SOC meter (A-3109).
• Use the remote wake-up button (A-4220) to bring the pack out of sleep mode, then test drive and recheck terminal torque.

Common cart-specific quirks to check:

• Charge port and onboard computer. Some carts route the charge circuit through an onboard computer (OBC) or a reed switch in the charge port. On several conversions, owners bridge or bypass that switch so only the battery positive and negative remain in the charge path. Confirm your cart's charge-port wiring before energizing.
• Old analog voltage gauge. Your factory dash "fuel" gauge is calibrated for lead-acid and will not read a lithium pack correctly. Use the included digital SOC meter and bypass or ignore the old gauge.
• Main / ceramic fuse and solenoid. A blown fuse or a solenoid that will not click on first power-up is almost always a wiring or polarity issue. Double-check every connection against your cart's diagram before applying load.
• 12V accessories. With no lead bank, there is no easy 12V tap. The included A-1272 converter is what powers your low-voltage electronics; it is required, not optional.

If you are not comfortable with the charge-port and 12V wiring on your specific cart, have a shop that has done lithium conversions handle the install. We are glad to talk through your cart before you order.
