If you're running a 72-volt golf cart or utility vehicle and you're watering batteries, cleaning corroded terminals, or losing range as your lead-acid bank ages, the Bolt Energy 73.6V 105Ah lithium battery replaces that entire routine with one sealed LiFePO4 unit. It is designed for 72-volt platforms including Club Car, Yamaha, EZGO, GEM, Bad Boy, Moke EV, Navitas, and Star EV M-Series carts.

The Bolt Energy 73.6V 105Ah battery is sold and searched under two names: "72V" and "73.6V." Both names refer to the same battery. The 72V name matches the lead-acid voltage class it replaces, while 73.6V is its actual nominal voltage, built from a 1P23S LiFePO4 cell configuration.

This battery is also a common upgrade for carts modified with high-speed controllers or AC motors, because 72-volt systems handle high power demands more efficiently than 36V or 48V systems. A heated version of the Bolt Energy 73.6V 105Ah battery is available for carts stored or charged in unheated garages, barns, or outdoors in cold climates.

Some carts require an aftermarket controller upgrade before the Bolt Energy 73.6V 105Ah battery can be installed. Fitment and controller requirements by cart model are listed in the Compatibility & Fitment tab.

Key Features

• No watering or terminal cleaning. The Bolt Energy 73.6V 105Ah uses LiFePO4 cells that do not sulfate like lead-acid, eliminating the routine maintenance a lead-acid bank requires.
• Bluetooth monitoring. The Bolt Energy 73.6V 105Ah includes a built-in Bluetooth receiver that pairs with a compatible device to show state of charge and battery data.
• Smart SOC meter. A dash-mounted state-of-charge meter is included so you can see remaining charge from the driver's seat without a phone.
• Smart BMS protection. The internal battery management system on the Bolt Energy 73.6V 105Ah manages charge cutoff, discharge cutoff, and reconnect voltage automatically to protect the cells from overcharge and over-discharge.
• CAN Bus communication. A CAN port allows a technician to pull battery data for diagnostic testing.
• IP66-rated enclosure. The powder-coated steel case is rated IP66 to resist dust and water exposure from normal outdoor cart use.
• Internal heating (heated version). The heated Bolt Energy 73.6V 105Ah warms itself automatically when charging begins below the minimum charging temperature, then shuts the heater off once it reaches the proper temperature.

What You Get When You Upgrade

Upgrading to the Bolt Energy 73.6V 105Ah replaces six 12V lead-acid batteries, plus their cables and connectors, with one sealed lithium unit and simplified wiring. Compared to lead-acid, owners typically gain longer usable range per charge, faster charging, and a battery that holds charge in storage with a self-discharge rate under 3% per month.

The Bolt Energy 73.6V 105Ah Standard Kit includes: the 73.6V 105Ah battery, Bluetooth receiver, Smart SOC meter, owner's manual, six 3/8" battery ring terminal connectors, ten 10" tie straps, Bolt Energy USA stickers, waterproof high-speed charger, mounting brackets with nuts and bolts, AC hardwire port, AC hardwire DECO cover plates, and a 15ft 12 AWG green lighted extension cord.

The Bolt Energy 73.6V 105Ah Professional Kit includes everything in the Standard Kit, plus a 30-amp voltage reducer, two 40" 2 AWG premium installation cables, a 400A solenoid, and a lead battery removal strap.

Recommended Applications

The Bolt Energy 73.6V 105Ah fits several owner situations. Use the descriptions below to identify where you land, then confirm your exact model in the Compatibility & Fitment tab.

• Replacing an aging lead-acid bank. If your batteries are losing range, need frequent watering, or are reaching end of life, the Bolt Energy 73.6V 105Ah is a direct lithium replacement for a 72-volt system.
• Carts with a high-speed controller or AC motor. These modifications draw more power than stock, and the 72-volt Bolt Energy 73.6V 105Ah handles that load more efficiently than a 36V or 48V battery.
• Factory 72-volt platforms. GEM utility vehicles, Bad Boy Buggy, Moke EV, Navitas 4-seaters, and Star EV M-Series are built around 72-volt systems from the factory.
• Cold-weather storage. The heated version of the Bolt Energy 73.6V 105Ah is built for carts kept outside or in unheated spaces through winter.
• Fleet operators. Removing watering and terminal maintenance across multiple carts saves labor that adds up over a fleet.

Not every 72-volt cart has enough tray space for this battery, and some models require a controller upgrade. Check the Compatibility & Fitment tab before ordering.
