76.8V 168Ah Fleet Lithium Battery — NexGen BMS
Maximum range, maximum torque, zero maintenance. 12,902Wh of fade-free energy for high-amperage 72V/76.8V vehicles, marine, and off-grid systems. Monitor state of charge, voltage, and cycle count via Bluetooth. Patent-pending fire suppression and a 300A NexGen BMS handle continuous high-draw applications without breaking a sweat.
What This Upgrade Fixes
- Eliminates voltage sag and sluggish performance common in aging lead-acid setups
- Cures range anxiety with consistent, fade-free power down to the last drop of capacity
- Removes hundreds of pounds of dead weight, improving acceleration, handling, and braking
- Ends the hassle of terminal corrosion, acid leaks, and seasonal battery watering
What's Included
1× 76.8V 168Ah Fleet Lithium Battery. Standalone bare battery unit. An 87.6V lithium charger, voltage reducer, custom wiring, and mounting brackets are not included — see our Bundle and Conversion Kit listings for complete drop-in packages.
Compatibility
Universal 76.8V power unit optimized for high-draw environments. Drops directly into custom 72V or 76.8V electrical systems. Built specifically for high-amperage 72V vehicles like Textron Prowler EV, Cushman Hauler PRO/PRO-X, and custom builds requiring 300A+ continuous draw, plus off-grid solar banks and deep-cycle marine.

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
Nice and easy install, they work great, much longer range and way better power. Best of all, NO MAINTENANCE
Tried cheaper lithium setups first and they couldn’t handle the amp draw. This one has been solid with no issues.
Absolutely Incredible Range. We replaced our 4 year old Trojan batteries this spring with the 210 AH dual battery kit and we are blown away! We use the buggy to secure the perimeter of a 300 acre lot in South Carolina. We typically put about 200 miles per week on this unit. We have been testing this kit for about a month now and we are getting every bit of 80 miles per charge. Its absolutely unbelievable. Thank you Fleet Lithium!
This screen was so easy to install. We installed our fleet lithium battery about 2 years ago, the screen just came out in April, it took 10 minutes to install and everything works perfectly. Thank you Fleet lithium!
After a few months of use I can confidently say this was worth it. No maintenance, great range, and consistent power every time. Huge upgrade from stock.
I should have just bought this first instead of wasting money on others.
I use my Prowler every day hauling feed and equipment. Other batteries kept shutting down under load. This is the only one that worked right. Glad I spent the money.
Runs strong every time. Exactly what I needed.
The range has doubled compared to my old setup. Installation was straightforward and the instructions were clear. I can now play multiple rounds without recharging.

No more issues with power cutting out. That alone made it worth it.

Handles hills and heavy loads without hesitation. Very impressed so far.
