Frequently Asked Questions
Does this battery include a charger?
No — this listing is the bare battery only. You'll need a matched 87.6V LiFePO4 charger to run it.
- Best value: Grab the 76.8V 168Ah Fleet Lithium Bundle — battery + CH8713 87.6V smart charger + cable set + voltage reducer + state-of-charge gauge. Everything for a complete drop-in.
- Charger only: Add the CH8713 87.6V Smart Charger alongside this battery.
Will this work in severe cold climates?
Yes. The NexGen BMS automatically activates internal heating below 32°F so the pack charges safely year-round.
How long will this battery actually last?
Engineered for over a decade of reliable performance and backed by our 10-year warranty.
What vehicles is this designed for?
Built for high-amperage 72V vehicles — Textron Prowler EV, Cushman Hauler PRO/PRO-X, lifted custom builds, and any application requiring 300A+ continuous draw with maximum range.
Can I integrate this with a sophisticated motor controller?
Yes. The integrated BMS provides CANBUS and RS485 ports for advanced motor controllers and telemetry systems.
Is there a vehicle-specific kit with brackets?
Yes. If you're converting a specific 72V vehicle, our 72V Conversion Kits include this exact battery plus a model-specific bracket, charger, voltage reducer, and all wiring — no fabrication required.

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.
