Upgrade Your Lvtong A617.2+2G to Fleet LithiumReplace the six 8V lead-acid batteries in your 48V Lvtong A617.2+2G with a single 51V LiFePO4 pack from Fleet Lithium. Complete conversion kit — battery, charger, vehicle-specific bracket kit, cables and hardware included. Half the weight, twice the range, and no watering, ever. Choose Your Capacity Capacity Range Best For 51V 65Ah Up to 27 mi Stock carts only 51V 105Ah Up to 50 mi Daily driving, shuttling 51V 168Ah Up to 75 mi All-day use, four passengers 51V 210Ah Up to 90 mi Max range, fleet use 65Ah is for stock motors and controllers only. A loaded four-passenger A617.2+2G should start at 105Ah, and 168Ah or higher is the right call for resorts and shuttle routes.

Before ordering, open the seat and confirm the visible battery count, voltage, chemistry and layout — never confirm fitment from nominal voltage alone. Controller Compatibility The 48V A617.2+2G uses Lvtong's exclusive AC controller with a 4kW AC asynchronous motor. The Fleet Lithium 51V pack is a direct match — no reprogramming, no controller upgrade, and no wiring changes. Confirm the visible controller and charger labels plus the stock motor/controller configuration before installation. Aftermarket or modified systems should be verified separately. Will this fit my A617.2+2G? Yes, on the 2026-current A617.2+2G running six 8V 150Ah lead-acid batteries on a 48V system. The included bracket kit is matched to the factory tray, so no drilling or vehicle modification is expected. Does it fit factory-lithium or modified builds? No. Factory-lithium builds and carts with modified motor or controller systems use a different electrical interface and are not covered by this kit. How long does installation take? 45–90 minutes with basic hand tools. Does it work in cold weather? Yes. The built-in heater activates automatically below 32°F so the pack can charge safely in winter — it's standard equipment, not an add-on.
