How To Buy Golf Cart Batteries?
Purchasing golf cart batteries involves evaluating battery type (lead-acid vs. lithium), voltage compatibility, capacity needs, and supplier reliability. Lithium-ion batteries (LiFePO4/NMC) offer higher energy density and longer lifespan but cost 30–50% more upfront. Lead-acid remains cost-effective for low-duty cycles. Always match the battery’s nominal voltage (e.g., 36V, 48V, 72V) to your cart’s system and verify Ah ratings for required range. Prioritize suppliers offering BMS-integrated packs and cycle-life warranties.

How do I choose between lead-acid and lithium batteries?
Lead-acid batteries dominate budget-focused applications, costing $150–$300 per 12V unit but requiring frequent maintenance. Lithium batteries (e.g., LiFePO4) last 2–3x longer, tolerate deeper discharges (80% vs. 50% DoD), and weigh 60% less. For carts used daily, lithium’s 2,000+ cycles justify the $800–$1,200 price per 48V 100Ah pack. Pro Tip: Check controller compatibility—lithium’s flat discharge curve may need voltage calibration.
What voltage and capacity specifications matter?
Golf carts typically use 36V, 48V, or 72V systems, determined by motor power. A 48V 200Ah lead-acid pack delivers ~9.6kWh, sufficient for 50–70 km. Lithium packs achieve similar range with 150Ah due to higher efficiency. Verify terminal layout (L-shaped vs. bolt-on) and dimensions—oversized cells may not fit trays. For hilly terrains, prioritize 72V systems with 150A+ continuous discharge.
| Parameter | Lead-Acid | Lithium |
|---|---|---|
| Cycle Life | 400–600 | 2,000–5,000 |
| Weight (48V 100Ah) | 55–65 kg | 18–22 kg |
| Charge Time | 8–10 hrs | 3–5 hrs |
Where should I source golf cart batteries?
Authorized dealers (e.g., Club Car, EZGO) ensure OEM-grade compatibility but charge 15–25% premiums. Third-party suppliers like Guangxi Taijun offer customizable LiFePO4 packs at $0.35–$0.50/Wh. Always request cycle-test reports and UL certifications. For lead-acid, Costco/Sam’s Club provide Trojans for $200–$350 with core-exchange programs. Pro Tip: Avoid unbranded “reconditioned” batteries—70% fail within 6 months.

FAQs
No—lithium requires CC-CV chargers with precise voltage cutoff (e.g., 58.4V for 48V LiFePO4). Lead-acid chargers risk overcharging, triggering BMS faults.
How often should I replace golf cart batteries?
Lead-acid: Every 1.5–3 years (300–500 cycles). Lithium: 5–8 years (2,000+ cycles), depending on DoD and temperature.
Are sodium-ion batteries viable for golf carts?
Not yet—current Na-ion prototypes (e.g., Haidar’s) offer 120 Wh/kg but lack cycle stability. Stick with LiFePO4 until 2026–2027 commercialization.
