Upgrade Your Lvtong A617.2+2G to Fleet Lithium
Replace 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.

Fitment Guide
| OEM Model | Years | Factory Pack | Bracket Shipped |
|---|---|---|---|
| Lvtong A617.2+2G | 2026–Present | 48V, six 8V 150Ah lead-acid | Vehicle-specific bracket kit (included) |
This kit covers the 2026-current A617.2+2G running six 8V 150Ah maintenance-free lead-acid batteries on the factory 48V 4kW AC drive. 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.

Let customers speak for us
GREAT SERVICE
Awesome kit. We Live in a very cold climate, our ranger gets a ton of use year round and especially during the winter so the cold weather performance was a must for us. We've had the kit installed for about a year now and it's been perfect. Customer service has been super helpful the one or two times we had questions and we've got a couple of neighbors who run the kits as well and they say the same thing. Kevin and his crew are really top notch!
The 12V voltage reducer corrected the unstable behavior that had affected the lights and other accessories. The output has remained steady through regular use.
The 51V replacement charger is easy to keep available as a backup and works without unnecessary controls. The battery reaches a complete charge consistently during normal use.
The Polaris Ranger EV bundle lined up well with the intended mounting area and the connections were easy to identify. Once installed, the vehicle felt smoother and more consistent through normal use.
The 51V replacement charger connected as expected and has charged the compatible battery consistently. The status indicators are easy to follow, and the unit feels solid in regular use.
Easy installation and great technical support.
After installing the Club Car 48V kit, throttle response felt more immediate and the vehicle no longer felt sluggish late in the charge. The cleaner battery compartment is another welcome improvement.
Cabels look great. Will be installing them by the end of the week. Frank
The BlueMax 200Ah marine battery has provided steady power for onboard electronics and normal time on the water. It is easier to handle than the older battery and has required very little attention between trips.
The parts for the EZGO TXT kit were organized clearly and the installation sequence made sense. The finished setup looks tidy and removes the routine upkeep of the old battery bank.
The 76V replacement charger replaced the previous unit without requiring a complicated setup. Charging has been predictable, and the connector fits securely.
The plug on the 51V replacement charger seats firmly and the unit maintains a normal charging cycle. The battery has been ready for use each time charging is complete.
The parts for the EZGO RXV kit were organized clearly and the installation sequence made sense. The finished setup looks tidy and removes the routine upkeep of the old battery bank.
The 12V voltage reducer provided a clear path for running standard accessories from the higher-voltage battery system. The result has been reliable and easy to service.
