What Battery Fits An EZ-GO ST 350 Gas Cart?
EZ-GO ST 350 Gas Carts typically use 6V lead-acid batteries in series configurations to power auxiliary systems or conversions. The Trojan TE35 6V 245Ah battery is a common fit, designed for heavy-duty applications like golf carts. For a 48V system, eight TE35 units are wired in series. These flooded lead-acid batteries require regular maintenance, including water refills and balanced charging. Use 48V 5A chargers with CC-CV protocols to extend lifespan.

Why choose Trojan TE35 batteries for EZ-GO ST 350?
The Trojan TE35 delivers 245Ah capacity at 6V, optimized for deep-cycle demands in utility vehicles. Its thick plates withstand 1,200+ cycles at 50% depth of discharge. Pro Tip: Group batteries by production date (within 6 months) to prevent voltage imbalances. Real-world example: Six TE35s create 36V for older carts, while eight achieve 48V for modernized EZ-GO models.
Can lithium batteries replace lead-acid in EZ-GO carts?
Yes, but 48V lithium systems require BMS and compatible chargers. Lithium’s 90% usable capacity (vs. 50% in lead-acid) cuts battery count. For instance, four 12V 100Ah LiFePO4 batteries replace eight 6V TE35s. Table below compares solutions:
| Type | Cycle Life | Weight |
|---|---|---|
| Trojan TE35 (Lead) | 1,200 | 67 lbs |
| LiFePO4 (Lithium) | 4,000 | 31 lbs |
How to maintain EZ-GO ST 350 batteries?
Check specific gravity monthly with a hydrometer (1.277±0.007). Equalize charge every 10 cycles at 7.4V per 6V battery for 2–4 hours. Keep terminals clean using baking soda solutions. Real-world failure point: Sulfation occurs if batteries stay below 12.4V (12V system) for 72+ hours.
What charging specs suit 48V EZ-GO systems?
48V chargers must deliver 5–10% of bank capacity (12.25–24.5A for TE35s). Bulk phase starts at 58V, absorption at 61V (25°C). Table shows charging parameters:
| Stage | Voltage | Current |
|---|---|---|
| Bulk | 58V | Max |
| Absorption | 61V | Tapering |
| Float | 54V | 2A |

FAQs
Eight 6V batteries wired in series (6V×8=48V). Ensure identical capacity and age for optimal performance.
Can I use car batteries in my EZ-GO?
No—starting batteries fail under deep-cycle use. Always use golf cart-rated batteries like the TE35.
What’s the lifespan of Trojan TE35 batteries?
3–5 years with proper maintenance. Replace when capacity drops below 60% (≈700 cycles).
