Frequently Asked Questions

Is this Bolt lithium battery compatible with my EZGO TXT?

Yes — this Bolt Energy 51.2V 105Ah kit is designed specifically as a drop-in lithium upgrade for the EZGO TXT and EZGO Express. It replaces your existing lead-acid battery pack with a single lithium unit. Always verify your cart's voltage before ordering.

What's the difference between the Standard Kit and the Pro Kit?

The Standard Kit includes the battery, charger, Bluetooth receiver, SOC meter, mounting hardware, and all wiring accessories needed for a complete installation. The Pro Kit adds a 400A solenoid, premium 2AWG cables, a 30-amp reducer, and a lead battery removal strap — ideal for professional installers or serious DIYers who want everything in one box.

How long does the Bolt lithium battery last in an EZGO TXT?

Bolt Energy lithium batteries are rated for 3,000–5,000 charge cycles, which translates to approximately 10–15 years of typical use. The 12-year warranty backs this up with industry-leading coverage against defects in materials and workmanship.

Do I need a new charger for my EZGO TXT when switching to lithium?

Yes — lithium batteries require a lithium-specific charger. This kit includes a waterproof high-speed charger designed specifically for the Bolt 51.2V battery, so you don't need to purchase anything separately.

How much range will I get after installing the Bolt lithium battery in my EZGO TXT?

Most EZGO TXT owners report 40–50% more range compared to lead-acid batteries, thanks to the consistent voltage delivery of LiFePO4 chemistry. Unlike lead-acid, lithium maintains full voltage until nearly depleted — no gradual slowdown as the charge drops.

How hard is it to install a Bolt lithium battery in an EZGO TXT?

Installation difficulty is moderate — most experienced DIYers complete it in 2–4 hours. The Standard Kit includes all necessary hardware and an owner's manual. Professional installation is recommended for those unfamiliar with golf cart electrical systems.

Will the Bolt lithium battery fit in my EZGO TXT battery compartment?

Yes — the "Thin" form factor (20" x 8.43" x 10.65") is designed to fit the EZGO TXT battery tray. Mounting brackets are included to secure the unit properly.
