How To Convert Golf Cart To Lithium Battery
Golf carts are a form of transportation for golf cart owners to travel around the golf course or community. Since golf carts need to be powered by batteries, most people are often troubled by the cumbersome maintenance and limited service life of traditional lead-acid batteries. In this guide, we will discuss with you how to convert golf cart batteries and upgrade them to lithium batteries. Let you say goodbye to the troubles brought by lead-acid batteries and maximize the performance of your golf cart.
Why Convert to Lithium Golf Cart Batteries?
Upgrading your golf cart battery to lithium battery can solve problems such as frequent replacement and high maintenance costs, short service life, and provide your golf cart with longer-lasting power, lighter weight, and zero maintenance.
When Do i Need To Replace My Lead-Acid Battery
- Physical Damage: Corroded terminals, warped internal plates, cloudy electrolyte liquid, or deformed battery cases indicate declining performance.
- Reduced Range: A noticeable drop in range despite full charging suggests the battery pack is losing capacity.
- Maintenance Burden: Regular watering and careful handling to prevent acid spills are time-consuming and hazardous.
What Are The Benefits Of Converting Golf Cart Lithium Batteries
- Extended Lifespan: With 3,000–5,000 charge cycles at 80% depth of discharge (DoD) and 15–25°C storage, they last 5-10 years, compared to 300–500 cycles (3–5 years) for lead-acid, lowering long-term costs.
- Consistent Power Delivery: Unlike lead-acid batteries, which weaken as they discharge, LiFePO4 lithium maintains steady voltage, ensuring reliable performance at any charge level.
- Weight Reduction: A lithium battery for golf cart saves 200–300 lbs (e.g., Temgo 48V 100Ah at 2 lbs vs. at 350 lbs for six 8V lead-acid), enhancing acceleration, maneuverability, and efficiency.
- Maintenance-Free: No watering or corrosion checks are needed, lithium golf cart batteries are safe for indoor storage with no toxic leaks.
- Enhanced Performance: High discharge currents (200A continuous, 600A peak for 3 seconds) support quick acceleration and power for hilly terrains.
- Fast Charging: Charge 5x faster (e.g., 5–6 hours for 100Ah with an 18A charger, varying by amperage and battery state), with 99% efficiency vs. 85% for lead-acid.
- Smart Features: Many models, like Temgo battery, include Bluetooth app monitoring and LCD screens for real-time charge, voltage, and cycle data.
- Environmental Benefits: LiFePO4 lithium batteries are recyclable, produce no lead pollution, and have a 20-30% lower carbon footprint due to higher efficiency, supporting sustainable use.
Choosing the Best Lithium Battery for Golf Cart
Selecting the best lithium battery golf cart system ensures compatibility and optimal performance. Consider these factors for an informed decision.
Match the lithium golf cart battery to your cart's voltage
36V Systems: Common in carts with six 6V lead-acid batteries.
48V Systems: Found in carts with six 8V or four 12V lead-acid batteries in series.
72V Systems: Rare, used in high-performance carts, confirm compatibility with manufacturers. Using a mismatched voltage (e.g., a 36 volt lithium golf cart battery in a 48V cart) can damage the electrical system. Check your cart's manual or battery setup.
Capacity Needs determines range
A 48V lithium golf cart battery with 100Ah (5.12 kWh) provides 40–50 miles on flat terrain, but hilly courses or heavy loads (e.g., passengers, gear) may reduce this to 30–40 miles./p>
A 36V golf cart lithium battery conversion kit with 100Ah (3.84 kWh) offers 30–40 miles./p>
Connect 2-6 batteries in parallel to increase capacity (e.g., two 48V 50Ah batteries yield 100Ah) without changing voltage.
Dimensions and Fit
Choose lithium golf cart batteries matching the GC2/GC8 size of lead-acid batteries for drop-in compatibility. Use spacers to secure fewer batteries (e.g., 2 instead of 6) in the tray.
Battery Type
LiFePO4 lithium batteries are ideal for golf carts due to their thermal stability, safety, and 3,000-6,000 cycle lifespan. NMC batteries provide higher energy density (5-10% more Wh/kg) but typically last 2,000-3,000 cycles and are less thermally resilient. Temgo's best lithium golf cart battery uses Grade A LiFePO4 cells for durability.
Battery Management System (BMS)
A battery management system (BMS) regulates temperature, prevents overcharging, over-discharging, and short circuits. Temgo's 200A BMS supports high discharge rates and offers Bluetooth monitoring.
Weight and Compatibility
Ensure battery weight (e.g., 61.73 lbs for Temgo 36V 100Ah) doesn't strain the cart's suspension. Verify compatibility with brands like Club Car, Yamaha, or EZGO, noting minor tray adjustments may be needed.
Choosing a Reputable Brand
Select batteries with certifications (e.g., CE, FCC, UL) and warranties service. Temgo's lithium golf cart batteries 48V conversion kit includes a warranty and IP65 waterproof casing.

Cost Considerations for Golf Cart Lithium Battery Conversion
The cost of converting to lithium batteries for golf carts varies but offers long-term savings more.
- Battery Cost: A 48V lithium golf cart battery (e.g., Temgo 48V 100Ah) costs $1,000–$1,500./li>
- Charger: A LiFePO4-compatible charger (e.g., 56.8V 18A) costs $200-$400.
- Accessories: Spacers, cables, connectors, and optional outlets add $50-$150.
- Savings: With 3,000–5,000 cycles, best lithium ion golf cart batteries eliminate frequent replacements (vs. $1,500 for six 8V lead-acid every 2–5 years) and reduce energy costs with 99% charge efficiency.

Safety Precautions for Converting Your Cart to Lithium
Safety is critical during a golf cart lithium battery conversion.
- Wear protective gear (gloves, safety glasses) to avoid shocks or acid exposure from lead-acid batteries.
- Disconnect all power sources to prevent short circuits.
- Handle lead-acid batteries carefully to avoid spills; dispose of them at certified recycling centers per U.S. EPA guidelines (e.g., through programs like Call2Recycle).
- Handle lithium golf cart batteries gently to avoid physical damage, which could cause thermal runaway (overheating risks).
- Ensure ventilation to avoid inhaling fumes during lead-acid battery removal.
- Follow manufacturer wiring and charger guidelines to protect the lithium battery golf cart system.
Step-by-Step Guide to Convert Your Golf Cart to Lithium Battery
Converting a golf cart battery to lithium is easy as long as you are well prepared and refer to the wiring diagram or video provided by the battery manufacturer. You can also follow the steps below to ensure a successful upgrade.
Step 1: Gather Tools and Equipment
Tools: Wrenches, screwdrivers, pliers, wire cutters/strippers, multimeter, battery puller, drill/bits, crimping tool.
Materials: Lithium golf cart battery, LiFePO4 charger, mounting brackets/spacers, cables/connectors, fuse, circuit breaker, insulation, heat shrink tubing.
Step 2: Determine Voltage and Capacity
Check voltage: Six 8V lead-acid batteries = 48V, six 6V = 36V, eight 9V = 72V. (If you are unsure, please consult the manufacturer of the old battery)
Select capacity (e.g., 100Ah for 40-50 miles) and wire 2-6 lithium batteries for golf carts in parallel for extended range.
Step 3: Remove Lead-Acid Batteries
Disconnect support brackets and cables, noting positive/negative connections to the speed controller
Use a battery puller to remove heavy lead-acid batteries safely.
Clean the battery tray thoroughly and inspect cables for corrosion, replacing if needed.
Step 4: Install Lithium Batteries
Place golf cart lithium batteries in the tray, ensuring even weight distribution and cable access.
Secure with L-brackets or spacers to prevent movement.
Step 5: Connect Parallel Bus Bars
Mount bus bars to connect the battery pack to the controller, charger pigtail, battery meter, and buck converter (for 48V to 12V accessories).
Connect all positive terminals to one side and negatives to the other, tighten with a wrench.
Step 6: Cable Management and Inspection
Organize wiring with zip ties for a tidy lithium battery golf cart compartment.
Verify battery breakers are on (typically opposite the plug side).
Use a multimeter to confirm connections before replacing the seat.
Step 7: Charge the Batteries
Use a LiFePO4-compatible charger (e.g., Temgo 56.8V 18A for 48V) with 14.2-14.6V output and 18-20A to avoid slow charging or damage.
Fully charge (5-6 hours for 100Ah with 18A, varying by charger and battery state) and test the cart on a short drive.
