51V 105Ah Fleet Lithium Battery — NexGen BMS
Drop-in 51.2V LiFePO4 replacement for tired 48V lead-acid banks. 5,376Wh of fade-free energy, half the weight of lead, and zero maintenance. Monitor state of charge, voltage, and cycle count via Bluetooth. Patent-pending fire suppression and a 300A NexGen BMS keep you running through every shift, round, and run.
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× 51.2V 105Ah Fleet Lithium Battery. Standalone bare battery unit. A 58.4V lithium charger, custom wiring, and mounting brackets are not included — see our Bundle and Conversion Kit listings for complete drop-in packages.
Compatibility
Universal 51.2V power unit engineered as a one-for-one replacement for 48V lead-acid battery banks. Drops directly into 48V golf carts, LSVs, UTVs, deep-cycle marine applications, and off-grid solar banks running factory 48V controllers — no reprogramming required for most vehicles.

Frequently Asked Questions
Does this battery include a charger?
No — this listing is the bare battery only. You'll need a matched 58.4V LiFePO4 charger to run it.
- Best value: Grab the 51V 105Ah Fleet Lithium Bundle — battery + CH5618 58.4V 18A smart charger + cable set + AC connector + digital state-of-charge gauge. Everything for a complete drop-in.
- Charger only: Add the CH5618 58.4V 18A 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.
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 golf cart (EZGO, Club Car, Yamaha, Advanced EV, etc.), our 48V Conversion Kits include this exact battery plus a model-specific bracket, charger, and all wiring — no fabrication required.
