The Husky 2 PWR is a 48V LiFePO4 (Lithium Iron Phosphate) battery built for golf carts, eUTVs, RVs, camper vans, and similar 48V applications. This PWR variation ships without inverter communications. Base capacity is 5.12kWh, and the platform is described by the manufacturer as configurable from 5.12kWh up to 20.48kWh.
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.
Expert Overview
Golf cart and eUTV owners replacing lead-acid banks run into the same three problems: voltage sag under load, watering and terminal maintenance, and short cycle life. The Husky 2 PWR addresses those with a 48V LiFePO4 pack rated at 5.12kWh at the base configuration, with the manufacturer stating the platform scales up to 20.48kWh through additional units. LiFePO4 chemistry holds voltage flatter across the discharge curve than flooded lead-acid, which is why torque and speed stay consistent on hills and rough terrain until the battery is nearly empty, rather than fading gradually.
The manufacturer states this battery includes an advanced BMS (Battery Management System) and self-heating for cold-weather charging protection. Specific BMS amperage limits (max continuous discharge/charge, peak discharge) are not provided in the source data for this listing. [NEEDS VERIFICATION]

Wiring & Configuration Limits
The manufacturer describes this platform as configurable from 5.12kWh up to 20.48kWh, indicating multiple units can be combined to reach higher capacity. The source data does not specify the exact number of units in series versus parallel, maximum series count, or maximum parallel count required to reach the 20.48kWh figure. [NEEDS VERIFICATION]
Do not mix this battery with lead-acid batteries in the same bank. Do not combine batteries of different ages or cycle histories in series or parallel strings. Confirm exact series/parallel wiring limits against the manufacturer documentation in the Resources tab before building a multi-unit bank.
Pro-Installer Tip
Charging any LiFePO4 pack below freezing without protection damages cells through lithium plating, a failure mode that will not show up immediately but permanently reduces capacity over time. The Husky 2 PWR's self-heating function is designed to prevent this by warming the pack before allowing a charge cycle to begin. Confirm the pack has reached operating temperature before initiating a charge in cold conditions, and verify this with a shunt-based battery monitor rather than assuming the BMS handled it silently. LiFePO4 chemistry supports 80-100% depth of discharge as a professional standard, well beyond the 50% DoD ceiling used for lead-acid — but that advantage only holds if the cells are never charged while frozen.
Key Benefits
