The Fairplay EVE ECO 48V golf cart typically uses six 8V lead-acid batteries wired in series to achieve a 48V system. However, modern replacements include lithium-ion (LiFePO4) battery packs designed for 48V operation. These must deliver 150–200Ah capacity for optimal range and feature a BMS compatible with 58.4V charging (for lithium). Standard configurations require IP67-rated waterproofing and Anderson SB-50 connectors.
What Are the Best Batteries for a Hillbilly Golf Cart?
What battery configuration works with the Fairplay EVE ECO?
The cart’s 48V system uses a six-battery lead-acid setup (8V each) or a single 48V LiFePO4 pack. Lead-acid configurations prioritize affordability, while lithium offers 60% weight reduction and 2,000+ cycles. Pro Tip: Verify terminal spacing matches OEM specs—incorrect placements risk short circuits.
A Fairplay ECO’s lead-acid bank requires 200–250Ah total capacity (e.g., six 8V 225Ah units). Lithium alternatives like a 48V 100Ah LiFePO4 pack provide comparable runtime with 30% faster charging. Real-world example: Swapping to lithium cuts charging time from 8 hours to 5.5 hours while reducing maintenance.
What chargers are compatible with this 48V system?
Use 48V-specific chargers (58.4V output for lithium, 57.6V for lead-acid) with Anderson SB-50 or TXT-style plugs. Mismatched voltages degrade batteries—lithium requires CC-CV charging, while lead-acid needs absorption stages.
Lead-acid chargers like the 48V18A model deliver 15–18A current, filling a 225Ah bank in 12–15 hours. Lithium chargers operate at higher 20–30A rates, leveraging faster charge acceptance. For instance, a 48V 30A LiFePO4 charger refills a 100Ah pack in ~3.5 hours. Always match plug types: EZGO TXT connectors won’t fit Fairplay ports without adapters.
| Charger Type | Lead-Acid | Lithium |
|---|---|---|
| Voltage | 57.6V | 58.4V |
| Current | 15A | 30A |
| Cycle Life Impact | 500 cycles | 2,000+ cycles |
Can I upgrade to lithium without modifications?
Yes, if the lithium pack has built-in BMS and matches voltage/connector specs. Lithium’s 48V nominal aligns with lead-acid systems, but chargers must be swapped. Why risk BMS failures? Always test voltage compatibility first.
A direct lithium replacement reduces weight from 300+ lbs (lead-acid) to 70 lbs, improving hill-climbing torque. For example, Dakota Lithium’s 48V 100Ah pack maintains OEM controller compatibility. However, older chargers lack lithium profiles—overcharging occurs if using lead-acid units. Transitional note: While initial costs are higher, lithium saves $400+ annually in replacement batteries.

FAQs
Absolutely. Use only lithium-rated chargers—lead-acid units can overcharge to 60V+, tripping BMS protection and shutting down the system.
How long do Fairplay ECO lead-acid batteries last?
Typically 3–5 years with monthly equalization. Deep discharges below 20% capacity halve lifespan.
Can I add a seventh battery for more range?
No—extra batteries create 56V+ systems, overwhelming 48V controllers. Upgrade to higher-capacity 48V lithium instead.
