How Do I Know What Batteries To Get For My Golf Cart?
Selecting golf cart batteries requires matching voltage (36V, 48V, or 72V), capacity (Ah), and chemistry (lead-acid or lithium-ion) to your vehicle’s specifications. Lead-acid remains common due to lower upfront costs, but lithium options like LiFePO4 offer longer lifespan, faster charging, and 30–50% weight reduction. Always verify controller compatibility—upgrading to lithium may require voltage adjustments. For example, a 72V 200Ah lead-acid pack provides ~14.4kWh, while lithium delivers 15–20% more usable energy.

How do I determine my golf cart’s voltage requirement?
Check existing batteries’ labels or manual—common systems are 36V (6x6V), 48V (6x8V), or 72V (6x12V). Pro Tip: Measure voltage at the charging port with a multimeter when unsure.
Golf carts typically use series-connected 6V, 8V, or 12V lead-acid batteries. A 48V system, for instance, combines six 8V units. But what if your cart has lithium? Lithium packs often consolidate voltage into single modules—a 72V lithium battery might replace twelve 6V lead-acid units. Practically speaking, mismatched voltages can overload motor controllers. For example, a controller rated for 48V±10% might fail with a 72V lithium pack. Always cross-reference OEM specs before switching chemistries.
| Voltage | Lead-Acid Configuration | Lithium Equivalent |
|---|---|---|
| 36V | 6x6V | 1x36V module |
| 48V | 6x8V | 1x48V module |
Lead-acid vs. lithium: Which is better for golf carts?
Lithium batteries offer 2,000+ cycles vs. lead-acid’s 300–500, with 50% faster charging. However, lead-acid costs $500–$800 less upfront for 48V systems.
While lithium dominates EV markets, golf carts still use 73% lead-acid globally (2024 Q1 data). Why? Many courses prioritize initial savings over long-term ROI. But consider runtime: A 48V 100Ah lithium pack delivers ~4.8kWh usable energy (80% DoD), whereas lead-acid provides ~2.8kWh (50% DoD). Beyond cost, lithium’s 70% weight reduction improves hill-climbing torque. Real-world example: Replacing a 600lb lead-acid bank with 200lb lithium cuts energy loss from rolling resistance by 18%.
| Metric | Lead-Acid | LiFePO4 |
|---|---|---|
| Cycle Life | 500 | 2,000 |
| Cost per kWh | $150 | $400 |
Battery Expert Insight
Modern golf carts increasingly adopt lithium-ion for operational efficiency, though lead-acid persists in cost-sensitive markets. Our 72V LiFePO4 systems achieve 15-year lifespans with 1C fast charging, outperforming lead-acid in energy density (150Wh/kg vs. 30Wh/kg). Always pair lithium upgrades with smart BMS and temperature sensors—thermal runaway risks drop below 0.01% with proper engineering.
FAQs
Yes, but ensure the motor controller accepts 20% higher voltage. Many 48V lead-acid systems tolerate 57.6V lithium (nominal 51.2V).
How often should I water lead-acid batteries?
Check monthly—top up with distilled water when plates are exposed. Neglect reduces capacity by 15–30% per year.
