36V vs 48V Lithium Golf Cart Batteries: Which is Best
When buying an electric golf cart battery, there are two main voltage rating options: 36V and 48V. The voltage rating of the battery depends on whether it is compatible with your golf cart type and model, and both options have their pros and cons.
In this article, Temgo will compare 36V and 48V golf cart batteries to help you choose the best system for your golf cart based on your needs and budget.
Understanding Voltage in Golf Carts
Different voltages drive golf cart motors, determining the amount of energy required for speed, torque, and range. A 36V system typically uses six 6-volt batteries in series, while a 48V system often employs six 8-volt or four 12-volt batteries.
Higher voltages, such as 48-volt systems, provide more power, allowing for greater speed and better performance on a variety of terrains. Higher voltage systems also work seamlessly with a torque controller upgrade kit, optimizing cart power delivery for enhanced performance.

To determine your carts voltage, inspect the cart battery compartment.
Count the holes in each battery (each hole typically represents 2 volts), multiply by the number of batteries, and sum the total. For example, six batteries with three holes each yield a 36 volt golf cart (3 holes × 2 × 6 = 36V).
However, in actual use, performance will be affected by different terrains, passenger loads and battery types (lead-acid batteries vs. lithium batteries), so voltage is a key but not the only factor.
Comparing 36V vs 48V Golf Cart Batteries
The 36V and 48V golf systems differ in performance, cost, and suitability. Below is a comparison to guide your decision when selecting a golf cart battery. Brands like Club Car, Yamaha, and Ezgo offer both systems.
| Feature | 36V System | 48V System |
|---|---|---|
| Energy Capacity | Lower than 48V system, suitable for shorter trips | Higher energy capacity than 36V systems, supports extended runtime |
| Speed | 12–20 mph, adequate for casual use | 18–25 mph, ideal for faster travel |
| Weight | Lighter and easier to handle: 61 lbs | Heavier than 36V lithium battery: 87.1 lbs |
| Cost Savings | Higher long-term costs with lead-acid, lower with lithium | Lower long-term costs with lithium due to durability |
| Upgrade Compatibility | Limited for high-performance accessories | Supports upgrades like golf cart LED lights |
| Applies to | Common in older models | Becoming more standard in newer models |
From Performance
A 36V golf cart performs well on flat surfaces, such as golf courses or community paths, but may struggle with heavy loads or steep inclines.
48V golf carts excel in demanding conditions, offering higher power for acceleration and grade-climbing capabilities, making them ideal for rough terrain or commercial use.
From Efficiency and Range
48V batteries draw less current, generating less heat and extending battery life. They offer a longer range per charge, reducing downtime. 36V systems are less efficient but sufficient for shorter trips.
Therefore, purchase according to your golf cart model compatibility and usage requirements.
From Cost
36V systems are more affordable upfront, appealing to budget-conscious buyers. 48V systems require a higher initial investment but provide long-term benefits through efficiency and durability, especially with lithium golf cart batteries.
Benefits of Lithium Golf Cart Batteries for Both Systems
Upgrading to lithium batteries enhances both 36V and 48V golf carts, offering significant advantages over traditional lead-acid batteries. Here’s why lithium golf cart batteries are a smart choice:
- Extended Lifespan: Lithium batteries last over 4,000 charge cycles (5-10 years) compared to 2–3 years for lead-acid batteries.
- Lightweight Design: Up to 50% lighter, improving efficiency and handling for upgraded golf carts.
- Fast Charging: Charge in 3–5 hours versus 6–8 hours for lead-acid, minimizing downtime.
- Maintenance-Free: No water refilling or corrosion checks, unlike lead-acid.
- Thermal Stability: LiFePO4 batteries resist thermal runaway, ensuring safety in high-heat environments like golf courses.
- Consistent Power: Stable performance across the charge cycle for reliable operation.
- Eco-Friendly: Free of hazardous materials, making them sustainable.
For example, a 48V lithium golf cart battery with 100Ah capacity offers high energy density for longer trips without added bulk. A 36V system with lithium batteries provides reliable performance for casual users, lasting longer than traditional lead-acid options. The table below compares lithium golf cart batteries for 36V and 48V systems, highlighting system-specific advantages.

Can I Convert a 36V Golf Cart to a 48V System
Converting a 36V golf cart to a 48V system can significantly enhance performance, offering faster speeds, better torque, and longer range. However, this complex process requires careful planning and professional expertise to ensure safety and compatibility.
Before undertaking a conversion, consider exploring nearby electric golf carts for sale and comparing the new prices of 48V golf carts at local dealers, as conversions are more expensive and risk damaging your old cart without professional conversion skills.
Key Components for Conversion
Batteries
Replace the 36V battery with six 8V batteries or four 12V batteries. 48V lithium golf cart batteries (e.g., 100Ah LiFePO4) are recommended for their compact size, lighter weight (80–100 lbs vs. 200+ lbs for lead-acid), and built-in Battery Management System (BMS) for safety.
Charger
Upgrade to a 48V compatible chargerto match the new 48V system and prevent overcharging or undercharging.
Controller
Install a 48V controller (typically 400–600 amps) to handle increased power demands. Ensure the controller matches the motor’s specifications to avoid overload.
Solenoid and Wiring
Replace the 36V solenoid with a 48V solenoid, including a matching diode and resistor to manage higher current. Rewire the system to accommodate 48V, checking for proper gauge to prevent overheating.
Motor
Verify the existing golf cart electric motor supports 48V (e.g., 3-5 kW rating). If incompatible, upgrade to a golf cart motor upgrade designed for 48V systems to ensure optimal performance.
Conversion Process
Assess Compatibility
Check the cart’s motor, controller, and wiring specifications. Older carts (10+ years) may require full system upgrades, increasing costs.
Select Components
Choose 48V lithium batteries for efficiency and ease of integration, ensuring they fit the battery compartment. Confirm controller and motor compatibility with the new voltage.
Professional Installation
Hire a certified technician to replace components, rewire the system, and test for safety. Improper installation can lead to electrical faults or fire hazards.
Test and Calibrate
After conversion, test the cart’s performance (speed, torque, range) and calibrate the controller to optimize the 48V system.
Costs and Considerations
Conversion costs, including a golf cart engine conversion kit, can range from $1,500-$3,000, depending on components and labor. For older carts, purchasing a new 48 volt cart maybe more cost-effective. Lithium batteries reduce long-term maintenance and weight, making conversions more viable.
Risks and Challenges
Incompatible components (e.g., undersized motor or wiring) can cause overheating, reduced performance, or system failure. Non-professional installations increase safety risks, such as short circuits or battery damage.
Recommendation consult a professional technician to assess your cart’s condition and ensure compatibility. Lithium golf cart batteries are ideal for conversions due to their high energy density, safety features (e.g., BMS protection against overcharging), and compatibility with upgrades like a torque controller upgrade kit. If conversion costs approach those of a new cart, search for electric golf cart for sale near me to explore modern 48V golf carts with factory-optimized systems.
