What Are Batteries For EZ Go Golf Cart?
Batteries for EZ Go golf carts are typically lead-acid or lithium-ion systems designed to power electric vehicles for extended ranges. Traditional setups use 6V, 8V, or 12V lead-acid batteries in series—for example, six 6V batteries (36V total) or eight 6V batteries (48V total). Modern lithium-ion alternatives like 48V 100Ah LiFePO4 packs offer lighter weight, faster charging, and longer cycle life. Key parameters include voltage configuration, capacity (Ah), and thermal stability, with lead-acid requiring regular maintenance and lithium-ion providing maintenance-free operation.
What voltage configurations are common in EZ Go carts?
EZ Go carts historically use 36V or 48V systems built from 6V or 8V lead-acid batteries. A 36V setup requires six 6V batteries (e.g., Trojan T-105), while a 48V system uses eight 6V units or six 8V batteries. Lithium-ion alternatives like 48V 100Ah LiFePO4 packs are gaining traction for their compact design and higher energy density. Pro Tip: Always verify your cart’s voltage requirements—mismatched configurations can damage motor controllers.
For instance, a Trojan T-105 6V/225Ah lead-acid battery provides ≈1.35 kWh per unit. Six in series deliver 36V/225Ah (8.1 kWh), sufficient for 18–25 km per charge. Comparatively, a 48V/100Ah LiFePO4 battery offers 4.8 kWh with 80% usable capacity but weighs 60% less. Why stick with lead-acid? Initial cost is lower, but lithium-ion’s 2,000+ cycles offset long-term expenses.
| Battery Type | Voltage | Cycle Life |
|---|---|---|
| Lead-Acid | 6V | 500–800 |
| LiFePO4 | 12.8V | 2,000–5,000 |
How do lithium-ion batteries enhance performance?
Lithium-ion batteries like 48V LiFePO4 packs reduce weight by 40–60% compared to lead-acid, enabling longer runtime and faster acceleration. Their flat discharge curve maintains consistent voltage, preventing power drops during uphill climbs. Charging times drop from 8–10 hours (lead-acid) to 2–4 hours, with no memory effect. Pro Tip: Use a lithium-specific charger—lead-acid chargers may overheat LiFePO4 cells, triggering BMS protection.
Take the 48V 100Ah LiFePO4 battery: it delivers 5.12 kWh (80% depth of discharge) versus 8.1 kWh from lead-acid, but its higher efficiency ensures comparable range. Plus, lithium tolerates partial charging without sulfation. What about cold weather? LiFePO4 operates at -20°C to 60°C, outperforming lead-acid’s 0°C–40°C range. However, lithium’s upfront cost is 2–3× higher, requiring ROI analysis based on usage frequency.
| Parameter | Lead-Acid | LiFePO4 |
|---|---|---|
| Weight (kg/kWh) | 25–30 | 8–12 |
| Efficiency | 70–85% | 95–98% |

FAQs
Yes, but upgrade the charger and controller. Lithium’s lower internal resistance demands compatible voltage regulation—mismatched components risk over-discharge or controller failure.
How long do lead-acid batteries last in EZ Go carts?
Typically 3–5 years with proper maintenance. Avoid discharging below 50% capacity, and equalize charges monthly to prevent sulfation.
