48V HUSKY 2 PWR - 5.12kWh LiFePO4 Battery (High Power)
The Husky 2 PWR is a 48V lithium iron phosphate (LiFePO4) battery built for golf carts, UTVs, and off-road or industrial equipment that currently runs on lead-acid. It stores 5.12kWh of usable energy in a sealed, IP65-rated case with an internal BMS and self-heating function for cold-weather operation. This PWR variant does not include inverter communications.
Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Why This Matters
Lead-acid golf cart batteries lose capacity in cold weather, sag under load, and need regular water top-offs. The Husky 2 PWR replaces that pack with a sealed LiFePO4 battery pack that manufacturer data indicates lasts over 4X longer than lead-acid, requires zero watering or maintenance, and charges faster. The internal BMS protects the cells from over-charge, over-discharge, and short-circuit conditions, and the self-heating feature is designed to allow charging in cold conditions without the manual intervention a lead-acid bank would need.
Battery Characteristics
- Chemistry: LiFePO4 (Lithium Iron Phosphate)
- Voltage: 48V nominal
- Capacity: 5.12kWh
- Casing Rating: IP65 (sealed against dust and water spray)
- Cold Weather Protection: Self-heating function for cold-weather charging
- Communications: This PWR variant does NOT include inverter communications
Wiring & Configuration Limits
Series and parallel expansion limits for the Husky 2 PWR are not specified in the manufacturer data provided for this listing. [NEEDS VERIFICATION] Do not wire this battery in series or parallel with other batteries, brands, or ages of cells until you confirm the supported configuration through the Resources tab or with BigBattery directly.
Pro-Installer Tip
Mixing an unverified number of Husky 2 PWR units in series or parallel without confirmed BMS-rated limits is the most common cause of cell imbalance and premature BMS lockout in golf cart lithium conversions. Left unmanaged, imbalance shortens usable capacity and can trip the BMS mid-round or mid-shift. Before wiring multiple units together, confirm the rated series/parallel configuration in the manufacturer documentation and monitor the bank with a shunt-based battery monitor so you can catch voltage drift between packs early. As a professional standard, plan your charge routine around the discharge depth the manufacturer rates for this chemistry rather than assuming lead-acid's typical 50% DoD applies here — LiFePO4 packs are generally documented for much deeper, more frequent cycling, but confirm the exact DoD rating for this model in the Resources tab before setting your controller's cutoff.

Compatibility & Fitment
The Husky 2 PWR is intended for 48V golf cart, UTV, and industrial/utility cart applications, and manufacturer copy also references RV, camper van, marine, and trolling motor use. It is compatible with 48V systems designed for LiFePO4 replacement of lead-acid banks.
It is NOT for use as a cranking/starter battery. Standard lead-acid chargers are NOT recommended — use a charger rated for LiFePO4. This PWR variant does NOT include inverter communications, so it is not a fit for systems requiring battery-to-inverter data exchange. Do not mix this battery with lead-acid batteries, or with lithium batteries of different age, brand, or state of health, in the same bank.
FAQ
- Does the Husky 2 PWR include inverter communications?
- No. This PWR variant does not include inverter communications.
- Can I use a standard lead-acid charger on this battery?
