Golf carts are no longer just for the fairway. Today, they're used in neighborhoods, campuses, industrial sites, farms, and resorts. But whether your cart hauls people, equipment, or groceries, the type of battery inside makes all the difference in performance, maintenance, and total cost of ownership.
In this post, we break down the main types of batteries used in golf carts, compare technologies, and help you choose the right one-from traditional lead-acid to cutting-edge lithium iron phosphate (LiFePO₄)
1. Why Battery Choice Matters
Golf carts are electric vehicles (EVs), and like any EV, their performance depends entirely on the battery. The battery's:
-Voltage determines power and compatibility with the cart's motor.
-Capacity (Ah) controls how far you can drive before recharging.
-Energy (Wh) shows how much total energy the battery holds.
-Cycle life determines how many charge-discharge cycles you'll get.
-Weight and size affect cart balance and handling.
The wrong battery can limit speed, reduce range, and increase maintenance. The right one can make your cart faster, lighter, longer-lasting, and more reliable.
2. Types of Golf Cart Batteries
2.1 Flooded Lead-Acid (FLA)
This is the oldest and most common battery technology. These batteries have removable caps so you can add distilled water — which must be done regularly.
Pros: Inexpensive, widely available
Cons: Heavy, short lifespan, requires regular maintenance
-Typical lifespan: 3–5 years
-Cycle life: ~500–1,000 cycles
-Cost: $600–$1,500 for a 48V set
2.2 AGM and Gel Lead-Acid
These are sealed lead-acid batteries — similar chemistry but no need to add water. AGM uses fiberglass mats to absorb the electrolyte, while gel batteries use a silica-based gel.
Pros: Maintenance-free, safer than flooded
Cons: Still heavy, shorter lifespan than lithium
-Typical lifespan: 4–6 years
-Cycle life: 600–1,200
2.3 Lithium Iron Phosphate (LiFePO₄)
LiFePO₄ is a type of lithium-ion battery with superior safety, longer life, and much better efficiency than lead-acid options. It's quickly becoming the gold standard in high-performance electric vehicles — including golf carts.
Pros:
- 3,000–6,000 cycle life (10+ years)
- Lightweight (50–70% less than lead-acid)
- Maintenance-free
- Fast charging
- High usable capacity (up to 90% of rated energy)
- Safe and thermally stable
3. Battery Voltage and System Configurations
Golf carts come in a few common system voltages:
-36V–Older carts, lower speed
-48V–Most modern carts, better performance and efficiency
-72V–High-end performance carts
Depending on the system voltage, carts use multiple batteries:
- 48V can be achieved with:
- 6 x 8V lead-acid batteries
- 4 x 12V batteries
- Or 1 x 48V lithium battery
Using a single lithium battery like the WEIZE 48V 105Ah unit simplifies installation, eliminates balancing issues, and offers better power delivery.
4. Product Spotlight: WEIZE 48V 105Ah LiFePO₄Battery
Specifications:
-Voltage: 48V
-Capacity: 105Ah
-Total Energy: 5,376Wh
-Chemistry: Lithium Iron Phosphate (LiFePO₄)
-Cycle Life: 4,000–6,000 cycles
-Bluetooth: Yes (monitor battery status via app)
-BMS: Built-in 100A Battery Management System
-Weight: ~100 lbs (lighter than lead-acid equivalents)
5. Comparing Battery Technologies
Even though lithium batteries like the WEIZE cost more up front, they cost significantlyless per use over time.
6. Do You Need a Special Charger for Lithium?
Yes—lithium batteries require a LiFePO₄-compatible charger that:
- Charges to 54.6V (for a 48V system)
- Has proper termination voltage
- Can communicate with the Battery Management System (BMS)
Many quality lithium batteries, including WEIZE, offer recommended charger options or compatibility guidelines. Using the wrong charger can reduce lifespan or cause safety issues.
7. Frequently Asked Questions
Can I replace lead-acid batteries with lithium?
Yes-as long as the lithium battery matches your system voltage and current needs. The WEIZE 48V 105Ah unit is a direct drop-in replacement for most 48V carts.
How long does a lithium battery last?
Up to 10+ years or 4,000–6,000 charge cycles, depending on how it's used.
Is LiFePO₄ safe?
Yes. Unlike other lithium-ion chemistries (e.g., NMC), LiFePO₄is thermally stable, non-flammable, and extremely safe-even under stress or high temperatures.
8. Conclusion: What Battery Is Right for You?
Choosing the right battery depends on your needs:
For most golf cart owners in 2024, LiFePO₄is the best choice — especially if you use your cart daily or want to avoid ongoing maintenance and replacement costs. And among lithium options, the WEIZE 48V 105Ah LiFePO₄Battery stands out with its high energy density, app connectivity, and long cycle life.
