How to Convert a 48V Golf Cart to Lithium Battery: Complete Guide

If your 48V golf cart still runs on six heavy lead-acid batteries, you could be carrying more than 300 pounds of battery weight while dealing with shorter range, slower charging, and regular maintenance. Lead-acid batteries also typically need replacement every 3–5 years, depending on usage and care.

The good news: converting a 48V golf cart to lithium is one of the easiest and most rewarding upgrades you can make. Switching to a 48V LiFePO4 lithium battery can reduce battery weight, extend usable runtime, and simplify ownership. For many golf carts, the conversion is a straightforward battery replacement that requires no cutting or welding. If your new battery is compatible with your cart's motor, controller, and electrical system, the installation may take around 1–2 hours with basic hand tools.

In this guide, you'll learn how to confirm your golf cart's voltage, choose the right 48V lithium battery for your motor and controller, complete the conversion step by step, and avoid common installation mistakes.

Why Golf Cart Owners Switch to LiFePO4 Lithium Batteries:

• Up to 70% lighter — a full lithium pack weighs about ⅓ of a lead-acid set, removing 300–400 lbs from your cart

• Up to 2× longer runtime — true usable capacity instead of the ~50% you can safely pull from lead-acid

• 5× faster charging — back on the course in a fraction of the time

• 10× longer lifespan — 4,000+ cycles vs. roughly 500 for lead-acid

• Zero maintenance — no water, no corrosion, no terminal cleaning

Let's walk through the 48V golf cart lithium conversion process, from choosing the right battery to completing your first test drive.

Step 1: Confirm Your Golf Cart Is Actually 48V

Before buying a lithium battery, confirm your golf cart's system voltage. Many Club Car Precedent/Onward, EZGO RXV/TXT, and Yamaha Drive 2 models use 48V systems, but voltage can vary by model year and configuration. Some older carts use 36V systems, so never rely on the model name alone.

3 Ways to Check Your Golf Cart's Voltage

1. Count the Batteries

Most traditional 48V golf carts use one of these lead-acid battery configurations:

• Six 8V batteries (6 × 8V = 48V)
• Eight 6V batteries (8 × 6V = 48V)
• Four 12V batteries (4 × 12V = 48V)

A traditional 36V cart typically uses six 6V batteries connected in series. If your cart already has a lithium battery, check its label for the nominal voltage and system specifications.

2. Check the Labels

Look at the battery labels, the cart's serial number plate, or the manufacturer's technical documentation. The voltage may be listed on the battery pack label or in the owner's manual.

If you're unsure, use your cart's make, model year, and serial number to confirm the original system voltage before purchasing a replacement battery.

3. Test with a Multimeter

With the cart turned off and the charger disconnected, set a digital multimeter to DC voltage. Measure across the main positive and negative terminals of the entire battery pack, not just an individual battery.

For a fully charged, rested lead-acid battery pack, these readings are useful reference points:

• 48V lead-acid system: approximately 50.9V
• 36V lead-acid system: approximately 38.2V

Allow the batteries to rest after charging before measuring, as surface charge can temporarily increase the reading. These values are reference points for lead-acid batteries, not universal voltage specifications for lithium packs. If your cart already has a lithium battery, check the battery manufacturer's specifications.

Important: A low reading does not automatically mean your cart is a lower-voltage model. A discharged or faulty battery pack can also show a lower voltage. If the reading is unclear, verify the original system voltage using the cart's specifications before proceeding.

Record Two More Specifications Before Choosing a Battery

Once you've confirmed your cart is 48V, find these two specifications. You'll need them to select a lithium battery that can safely power your motor and controller.

• Motor Power Rating (kW): Check the motor label or owner's manual. This helps determine the power output your battery needs to support.
• Controller Current Rating (A): Look for the controller label or consult the manufacturer's documentation. Confirm the maximum battery-side current, rather than relying solely on the motor's phase-current rating.

These specifications will help you match your cart with a lithium battery that has the appropriate continuous and peak discharge capabilities.

Next, let's look at how to choose the right 48V lithium battery for your golf cart.

Step 2: Choose the Right 48V Lithium Battery

Not every 48V lithium battery is suitable for every golf cart. To get the performance and reliability you expect, match your battery's continuous and peak discharge capabilities to your motor, controller, and driving conditions.

A battery with insufficient BMS discharge capacity may trigger protection during acceleration, climbing, or carrying heavy loads. Before choosing a battery, check your controller's maximum battery-side current, your motor's power rating, and the battery's BMS specifications.

Find the Right Enjoybot Battery for Your Golf Cart

Use the guide below to narrow down your options based on your cart's configuration, available battery space, and typical use.

48V 105Ah Kit vs. 48V 105Ah Mini Kit

Both kits support compatible 48V golf carts with motors up to 6kW and controllers rated up to 500A. The main difference is battery compartment fit.

The 48V 105Ah Conversion Kit is designed for standard and narrow battery compartments, while the 48V 105Ah Mini Conversion Kit is intended for carts with particularly limited installation space.

Before ordering, compare the battery and mounting dimensions with your cart's available battery compartment.

How Much Battery Capacity Do You Need?

Battery capacity affects how long your golf cart can run between charges, while the battery's discharge capability determines whether it can meet your motor and controller's power demands.

As a general starting point:

• Standard golf carts and everyday use: A 100–105Ah battery is a practical option for many golf carts, offering a balance of usable capacity, installation flexibility, and driving range.
• Hilly courses, lifted carts, or higher passenger loads: Consider a battery with sufficient discharge capability for your controller, along with enough capacity for your typical driving conditions.
• Extended Driving and Cold-Weather Use: The 48V 150Ah Heated Battery Set (4 × 12V) combines higher battery capacity with built-in self-heating functionality. It's a suitable option for compatible golf carts used for longer driving days, heavier loads, or in colder conditions. Always verify the battery's discharge ratings and heating operating requirements before installation.

Remember that a higher Ah rating does not automatically mean a battery can deliver more power. Always check both battery capacity (Ah) and BMS discharge ratings (A) when selecting a replacement.

Single-Battery Kit or Four 12V Batteries?

Enjoybot offers two common approaches to a 48V golf cart lithium conversion. Both use LiFePO4 technology, but their installation and space requirements differ.

Option 1: Single-Battery Conversion Kit

48V 100Ah/105Ah All-in-One Conversion Kit consolidates the battery pack into one unit and includes conversion accessories for a streamlined installation. It reduces the number of individual battery connections and can simplify battery placement and wiring. 

Always check the battery's dimensions and the kit's mounting requirements against your cart before ordering.

Option 2: Four 12V Batteries Connected in Series

A four-battery set uses four 12V batteries connected in series to create a nominal 48V system. This arrangement offers flexible placement and allows each battery to be handled individually. Group 31-sized batteries may fit many standard battery trays, but verify the dimensions and terminal clearance of your specific cart.

When connecting batteries in series, use compatible batteries with matching specifications and follow the manufacturer's installation instructions. Confirm that the complete pack's voltage, current capability, and charging requirements are suitable for your cart.

Neither setup is universally a drop-in replacement. Battery compartment dimensions, mounting hardware, cable connections, and the original charging system may require attention during conversion.

Don't Forget the Charger

A lithium conversion also requires a compatible charging system. Lead-acid chargers use different charging profiles and may not fully charge a LiFePO4 battery or may be unsuitable for its BMS and charging specifications.

Use a dedicated 48V LiFePO4 charger that matches your battery's specified charging voltage and current. Many Enjoybot conversion kits include a compatible charger, but confirm the included accessories and charger specifications for your selected model before installation.

If your cart has an onboard charger (OBC), verify its compatibility with the lithium battery before proceeding. Some carts may require an OBC bypass or other charging-system modifications, depending on the original configuration and conversion kit.

Once you've confirmed battery capacity, discharge capability, physical fit, and charger compatibility, you're ready to move on to the installation process.

Step 3: Gather Tools & Prepare for Safety

You'll need:

• Socket wrench set (typically 9/16" or 1/2", depending on your cart)
• Battery terminal brush or wire brush
• Multimeter
• Insulated gloves and safety glasses
• Cable ties or heat-shrink tubing (if reusing or rerouting cables)
• Your new lithium batteries and compatible lithium charger

Safety first:

• Work in a dry, well-ventilated area.
• Put the cart in Tow/Maintenance mode (or disconnect the Run/Tow switch) to disable the controller and solenoid.
• Remove the key and disconnect any 12V accessories.
• Treat all battery terminals as live. Never allow a wrench or other metal tool to bridge a positive terminal and the chassis or another terminal.

Step 4: Remove the Old Lead-Acid Batteries

1. Disconnect the negative terminal first, then the positive terminal. If your cart has multiple batteries connected in series, work carefully through the connections and avoid allowing any metal tool to contact two terminals at the same time.
2. Remove the hold-down brackets and carefully lift out the batteries one at a time. Lead-acid batteries can weigh 60–70 lbs each, so use proper lifting technique and ask for help when needed.
3. Clean the battery bay. Remove any acid residue, corrosion, and debris from the battery tray and surrounding area. Use a damp cloth or an appropriate cleaning solution as needed, and allow the area to dry completely before installing the new batteries.

💡 Pro Tip: Take a photo of the original battery layout and wiring before disconnecting anything. Even though a lithium conversion typically uses a simpler setup, the photo can serve as a useful reference during installation.

Step 5: Install & Balance the Lithium Batteries

Before installation, make sure all batteries are compatible with your golf cart and approved for the intended series configuration. For four-battery setups, use four identical 12V batteries of the same model and capacity.

Single-Battery Kits (48V 100Ah / 105Ah)

1. Place the battery in the battery tray and secure it using the appropriate hold-down bracket.
2. Connect the cart's main positive and negative cables to the corresponding battery terminals, ensuring correct polarity.
3. Tighten all connections to the manufacturer's recommended torque and make sure the cables are secure and free from excessive strain.

Four 12V Batteries Wired in Series (48V 100Ah / 150Ah Sets)

Important: Balance the batteries before connecting them in series.

When multiple 12V LiFePO4 batteries are connected in series, differences in voltage and state of charge can affect pack performance and usable capacity. Follow these steps to balance the batteries before installation:

1. Fully charge each battery individually. Use a compatible 12V LiFePO4 charger and follow the charging voltage specified in the battery's user manual.
2. Connect the four batteries in parallel. Connect all positive terminals together and all negative terminals together, using suitable cables and secure connections. Leave them connected for at least 12 hours to allow their voltages to equalize.
3. Disconnect the parallel connections. Use a multimeter to measure the voltage of each battery individually.
4. Check the voltage difference. Compare the highest and lowest readings. The difference should be no more than 0.04V (40mV). If the difference exceeds 40mV, do not proceed with series installation. Recharge and rebalance the batteries before checking again.

Once the batteries are balanced, proceed with the installation:

1. Position and secure the batteries. Place all four batteries in the battery tray and secure them using the appropriate hold-down brackets.
2. Connect the batteries in series. Connect the negative terminal of Battery 1 to the positive terminal of Battery 2. Then connect the negative terminal of Battery 2 to the positive terminal of Battery 3, followed by the negative terminal of Battery 3 to the positive terminal of Battery 4.
3. Connect the main pack cables. Connect the golf cart's main positive cable to the positive terminal of Battery 1 and the main negative cable to the negative terminal of Battery 4.
4. Check all connections. Verify the polarity and wiring layout, tighten all terminals to the manufacturer's recommended torque, and ensure that exposed connections are properly protected.

Step 6: Check the Charger & Controller Compatibility

Charger

Replace your lead-acid charger with a compatible 48V LiFePO4 charger, or use the lithium charger included with your Enjoybot kit.

For a typical 51.2V (16S) LiFePO4 battery, the charging voltage is 58.4V. Always follow the charging specifications for your specific battery model and use a charger designed for LiFePO4 batteries.

Never use a lead-acid charging profile unless it is explicitly approved for your battery.

Controller

Most stock golf cart controllers can be retained during a lithium conversion, provided their specifications are compatible with the new battery.

Before installation, check that:

• The controller's continuous and peak current requirements are within the battery's BMS discharge current limits.
• The motor power and controller settings are compatible with the battery's specifications.
• Any required voltage or current settings are configured according to the battery and controller manufacturers' recommendations.

A controller replacement or adjustment may be necessary if the existing controller exceeds the battery's discharge limits or is otherwise incompatible.

12V Accessories & Voltage Reducer

If your cart has a 48V-to-12V voltage reducer, check that its input voltage range is compatible with your new lithium battery. If compatible, it can generally continue powering your 12V accessories.

If your original setup powered 12V accessories by tapping into part of the lead-acid battery pack, rewire those accessories to a compatible voltage reducer or dedicated 12V power supply.

Never draw power from a single battery within a series-connected lithium pack. Doing so can cause battery imbalance and may trigger the BMS protection system.

Step 7: Test Drive & First Charge

1. Check the Installation

Double-check all battery connections, cable routing, and terminal tightness. Make sure the battery is securely mounted and all exposed terminals are properly protected.

Return the cart to Run mode, turn the key on, and check that the dashboard and battery meter respond normally.

2. Perform a Safe Test Drive

Start with a slow test drive in a safe, open area. Check the acceleration, braking, and overall operation of the cart.

If everything works normally, gradually increase speed and load. Stop immediately if you notice unusual noises, warning lights, unexpected power loss, or other abnormal behavior.

3. Fully Charge the Battery

Before your first extended drive, fully charge the battery using the compatible lithium charger.

Charging time depends on the battery's remaining capacity and the charger's output current. Follow the battery and charger manuals, and allow the charging cycle to complete according to the charger's indicators.

4. Monitor Your Battery

For Bluetooth-equipped Enjoybot batteries, download the corresponding app to monitor battery voltage, state of charge (SOC), temperature, and other battery data in real time.

Search for the app in the Apple App Store or Google Play, or scan the QR code provided on the battery or in the user manual.

Refer to your battery's user manual for app connection and monitoring instructions.

Cost Breakdown: What Does a Lithium Conversion Cost?

The upfront cost of a lithium conversion is typically higher than replacing a lead-acid battery pack, but the total cost of ownership depends on battery life, charging frequency, maintenance, and how often the cart is used.

A quality 48V lithium conversion can cost $900–$1,500+, depending on battery capacity, battery configuration, charger, and other components. Enjoybot golf cart batteries are backed by a 10-year warranty, helping provide long-term coverage for your investment.

Common Mistakes to Avoid

1. Skipping the 40mV balance check on series battery sets — make sure the batteries are properly balanced before connecting them in series.
2. Reusing a lead-acid charger — a lithium battery requires a compatible LiFePO4 charging profile. Using an incompatible charger may result in improper charging and reduced battery performance or service life.
3. Ignoring battery and cart compatibility — the battery's BMS discharge limits, motor power, controller configuration, and the cart's actual power requirements all need to be compatible. Do not select a battery based solely on the controller's advertised peak current. Check the battery's specifications and the compatibility table in Step 2 before installation.
4. Mixing old and new batteries — never combine used lead-acid batteries with lithium batteries, or mix lithium batteries with different capacities, models, or significantly different usage histories in the same series pack.
5. Ignoring cold-weather charging — standard LiFePO4 batteries should not be charged below 32°F (0°C). If you use or store your cart in cold climates, choose a self-heating model designed to manage low-temperature charging.
