How Many Batteries in a 48 Volt Golf Cart and Replacement Cost

Understanding how many golf cart batteries you need for a 48-volt system and the replacement cost helps you budget and maintain peak performance.

Standard 48-Volt Battery Configurations

A 48-volt golf cart battery system can be configured in several ways, depending on battery voltage:

• Six 8-Volt Batteries: The most common setup (6 × 8 V = 48 V). This offers a balance of capacity and cost.
• Eight 6-Volt Batteries: Also popular (8 × 6 V = 48 V). Provides higher amp-hour capacity for longer range.
• Four 12-Volt Batteries: Less common (4 × 12 V = 48 V). Fewer units to install but each battery is larger and heavier.

Choosing the Right Battery Type

When selecting batteries for your 48-volt system, you’ll choose between lead-acid (flooded or AGM) and lithium-ion:

• Flooded Lead-Acid: Affordable entry-level option. Requires monthly water top-ups and terminal cleaning.
• AGM (Absorbent Glass Mat): Maintenance-free sealed lead-acid. More expensive but resists vibration and leakage.
• Lithium-Ion: Premium choice with highest cycle life, faster charging, lighter weight, and deeper discharge.

Replacement Cost for a 48-Volt System

The total cost to replace golf cart batteries in a 48-volt cart varies by battery type and brand:

• Six 8-Volt Flooded Lead-Acid: $120–$180 each, totaling $720–$1,080.
• Eight 6-Volt Flooded Lead-Acid: $100–$150 each, totaling $800–$1,200.
• Four 12-Volt Flooded Lead-Acid: $130–$200 each, totaling $520–$800.
• Six 8-Volt AGM: $150–$220 each, totaling $900–$1,320.
• Lithium-Ion Pack: Complete 48 V lithium kits range from $1,500 to $3,000+

Labor and disposal fees may add $50–$150, depending on your dealer.

Factors Affecting Replacement Costs

Several variables influence final costs:

• Brand and Warranty: Premium brands command higher prices but offer longer warranties.
• Dealer Labor Rates: Installation fees vary by region and service complexity.
• Battery Life Expectancy: Lithium batteries last 8–10 years; lead-acid lasts 4–6 years.
• Usage and Charging Habits: Frequent deep discharges shorten lead-acid lifespan.

Tips for Extending Battery Life

Proper maintenance can delay replacement:

• Charge after each use; avoid letting batteries go below 50% state of charge.
• For flooded batteries, check water levels monthly and top up with distilled water.
• Clean terminals regularly and apply anti-corrosion spray.
• Use a smart charger with multi-stage charging to prevent overcharging.
• Store your golf cart in a cool, dry place to minimize thermal stress.

Conclusion

Most 48-volt golf carts use six 8-volt or eight 6-volt batteries. Replacement costs range from around $520 for basic flooded lead-acid setups up to $3,000 for advanced lithium packs. By choosing the right battery type and following proper maintenance, you can ensure reliable performance and maximize the lifespan of your golf cart batteries.
