Choosing the right battery for your EZ-GO TXT electric golf cart is crucial for performance, range, and longevity. Most models operate on 36V or 48V systems, using deep-cycle lead-acid or lithium-ion batteries. Upgrading to lithium, such as Redway Battery’s LiFePO4 packs, offers reduced weight, extended lifespan, and maintenance-free operation while ensuring safe and efficient energy delivery for daily or heavy-duty use.
What Voltage System Does the EZ-GO TXT Use?
EZ-GO TXT carts generally run on 36V or 48V systems. The 36V configuration combines six 6V batteries, while 48V setups use either six 8V batteries or eight 6V units. Accurately identifying your cart’s voltage is essential before purchasing replacements, as mismatched voltages can damage the motor or controller.
36V systems typically provide 3–5kW of power, suitable for flat terrain, while 48V systems offer up to 25% more torque for inclines or heavier loads. Using a multimeter, a fully charged 6V battery should read 6.3–6.4V. Transitioning from lead-acid to lithium requires ensuring charger and controller compatibility to handle stable discharge profiles.

| Voltage | Battery Count | Ideal Terrain |
|---|---|---|
| 36V | 6 × 6V | Flat terrain |
| 48V | 8 × 6V / 6 × 8V | Hills, heavy loads |
Can Lithium Batteries Replace Lead-Acid in EZ-GO TXT?
Yes, LiFePO4 lithium batteries are direct replacements when voltage matches. A 36V lithium pack can weigh 70% less than lead-acid while doubling usable capacity. Lithium batteries are maintenance-free and support over 2,000 cycles, ideal for frequent use in golf courses or community carts.
Redway Battery offers reliable lithium solutions with integrated Battery Management Systems (BMS) for safety. Retrofitting requires checking that your charger supports CC-CV profiles, and higher voltages may need controller upgrades.

How to Calculate Required Battery Capacity?
Battery capacity is calculated by multiplying ampere-hours (Ah) by system voltage. For instance, six 225Ah 6V batteries in a 36V TXT yield 8.1 kWh. Real-world range depends on payload, terrain, and tire pressure.
For heavy-use scenarios, consider 20–30% extra capacity to prevent deep discharges. Lithium batteries allow deeper discharges (80–90% DoD) compared to lead-acid (50%), effectively doubling usable energy. Redway Battery guarantees ±10% tolerance on capacity, ensuring predictable performance.
What Connectors Suit EZ-GO TXT Battery Upgrades?
Standard 5/16″ terminal lugs work for most lead-acid replacements. Lithium upgrades often require Anderson SB175 connectors to handle higher currents safely. Cable gauge must match peak amp loads; for example, a 48V 200Ah lithium pack drawing 400A requires 2/0 AWG cables. Proper connections prevent voltage drops and overheating.

| Terminals | F2 Posts | M8 Bolts |
| Charger | On/Off | Smart CAN |
| BMS | N/A | Integrated |

FAQs
Can I use car batteries in my EZ-GO TXT?
No. Automotive SLI batteries cannot handle deep discharge cycles needed for golf carts.
How often should I water lead-acid batteries?
Top up distilled water monthly when plates are exposed. Avoid overfilling beyond cell indicators.
Do lithium batteries require ventilation?
LiFePO4 cells emit minimal gas, but maintain 1-inch clearance around packs for heat dissipation.
Which battery size fits older EZ-GO TXT models?
Older models often use BCI Group GC2 6V batteries. Confirm voltage and capacity before replacement.
Are lithium battery upgrades worth the cost?
Yes, for frequent use. Reduced weight, extended lifespan, and minimal maintenance provide significant long-term benefits. Redway Battery offers dependable options tailored for OEM compatibility.
Conclusion
Selecting the right battery for your EZ-GO TXT ensures optimal performance, longer lifespan, and safer operation. Lead-acid batteries remain reliable, but lithium upgrades from Redway Battery offer superior weight reduction, cycle life, and maintenance-free operation. Always verify voltage, capacity, and compatibility with your charger and controller. Thoughtful choices deliver a smooth ride, efficient energy use, and long-term savings.
