The EZ-GO TXT 2006-Up electric cart typically uses 48V lead-acid battery systems, configured with six 8V or four 12V batteries wired in series. Lithium-ion upgrades (LiFePO4) are increasingly popular for their weight savings and extended lifespan. Optimal capacity ranges from 150–220Ah for moderate-range applications, with battery trays supporting standard Group GC2 or GC8 sizes. Pro Tip: Always verify charger compatibility—48V chargers must deliver 58–63V output for lead-acid and 58.4V max for lithium systems.

What voltage does a 2006-Up EZ-GO TXT require?
Post-2006 EZ-GO TXT models use 48V systems for improved torque and efficiency. Earlier models (pre-2014) occasionally used 36V, but OEM specifications since 2006 prioritize 48V with lead-acid or lithium configurations. Always check the controller label—48V models display “CURTIS 48V” or similar coding.

Beyond voltage compatibility, battery arrangement matters. A standard 48V pack combines six 8V lead-acid batteries (e.g., Trojan T-875) or four 12V units in series. Lithium conversions often use single 51.2V LiFePO4 packs. Pro Tip: Use a multimeter on existing batteries—fully charged 8V cells read ~8.9V, while 12V units hit ~12.7V. Mixing voltages risks controller damage. For example, a 48V 200Ah lithium system reduces weight by 60% compared to lead-acid, extending range to 35–50 miles per charge.
Are lithium batteries compatible with 2006-Up TXT models?
Yes, 48V LiFePO4 batteries are drop-in replacements if voltage matches OEM specs. Lithium packs require battery management systems (BMS) to protect against over-discharge and integrate with TXT’s controller. Redway Battery’s 48V 100Ah lithium system delivers 5.12kWh with 2,000+ cycles.

Practically speaking, lithium upgrades demand modifications. The stock charger won’t work—lithium requires CC-CV charging up to 58.4V. You’ll need a compatible charger and possibly a voltage reducer for 12V accessories. Thermal management is simpler with lithium, as they tolerate -20°C to 60°C. Pro Tip: Prioritize batteries with UL-certified BMS—rogue voltage spikes can fry $500+ controllers.
| Parameter | Lead-Acid | Lithium |

| Cycle Life | 500–800 | 2,000–5,000 |
How to confirm battery tray dimensions?
EZ-GO TXT battery trays measure 39.5″ L x 26.5″ W, accommodating six 8V or four 12V batteries. Lithium replacements often occupy 50–70% of this space, freeing room for accessories. Always verify group size compatibility:
Group GC2 (8V): 10.3″ L x 7.1″ W x 10.9″ H
Group GC8 (12V): 12.5″ L x 6.8″ W x 8.9″ H
Redesigning tray layouts? Use 1/4″ steel plates to reinforce shelves when swapping to lighter lithium. Pro Tip: Leave 1″ clearance around lithium packs for airflow—dense arrangements trap heat.
What charger specifications are needed?
Match charger output to battery chemistry:
Lead-Acid: 48V chargers with 58–63V output (e.g., 15A Powerwise QE)
Lithium: 58.4V max CC-CV chargers (e.g., Redway’s 20A LiFePO4 unit)
Charging protocols differ starkly. Lead-acid needs equalization cycles monthly, while lithium thrives on partial charges. For example, a 48V 150Ah lead-acid pack requires 8–10 hour charges at 15A, whereas lithium finishes in 4–5 hours at 30A. Pro Tip: Smart chargers with temperature sensors prevent winter overcharging—lead-acid efficiency drops 20% below 10°C.
| Feature | Lead-Acid Charger | Lithium Charger |
|---|---|---|
| Voltage Range | 58–63V | 54.8–58.4V |
| Charge Time | 8–10h | 3–5h |

FAQs
No—automotive SLI batteries lack deep-cycle capacity. Use golf-specific GC2/GC8 lead-acid or LiFePO4 packs rated for 80% DoD.
How often should I replace TXT batteries?
Lead-acid: 4–5 years with proper maintenance. Lithium: 8–10 years, contingent on BMS health and charge habits.
Do lithium batteries void EZ-GO warranties?
Potentially—dealer powertrain warranties often exclude third-party batteries. Consult your service agreement before upgrading.
