What Battery Fits EZ-GO TXT (2006 Up) Electric Cart?
The EZ-GO TXT (2006 and newer) electric golf cart typically uses 36V or 48V lead-acid battery systems as standard configurations. These systems consist of six 6V batteries (for 36V) or six 8V batteries (for 48V) wired in series. For lithium-ion upgrades, 36V/48V LiFePO4 batteries with BMS protection and D-shaped charging port compatibility (e.g., 73345-G01 plug) are viable replacements, though controller adjustments may be required.

What voltage systems do EZ-GO TXT carts use?
2006+ EZ-GO TXT models utilize either 36V (six 6V) or 48V (six 8V) lead-acid battery banks. The 48V system became standard after 2014 for improved torque and efficiency. Always verify your cart’s voltage via charger port labels or battery count: 6 batteries = 36V (if 6V each) or 48V (if 8V each).
Most 2006-2013 TXT models shipped with 36V configurations using Trojan T-105 6V batteries. Post-2014 units often upgraded to 48V for better performance in hilly terrain. Pro Tip: Check the controller label—codes like “1206-XX” ending with 36 or 48 indicate system voltage.
Are lithium batteries compatible?
Yes, 36V/48V lithium batteries work with TXT carts when using proper adapters. LiFePO4 packs like 36V 100Ah (3.6kWh) provide 30% more range than lead-acid. Ensure the BMS supports 150A continuous discharge for hill-climbing demands. Chargers must match lithium protocols (e.g., 42V cutoff for 36V LiFePO4 vs. 45V for lead-acid).
For example, Redway Battery’s 48V 60Ah lithium pack achieves 35-mile range vs. 20 miles with lead-acid. Transitional note: While upfront costs are higher, lithium’s 2,000+ cycles outlast lead-acid’s 500-cycle lifespan by 4x.

FAQs
No—EZ-GO’s series wiring requires 6V/8V batteries. Twelve-volt units create incompatible voltage (72V with six 12V), potentially frying controllers.
Do lithium batteries need special maintenance?
Unlike lead-acid, lithium requires no watering. However, store carts at 50% charge if unused for months to prevent BMS drain. Annual voltage calibration via full discharge/charge cycle optimizes range.
