The 48V HUSKY 2 INV is a 5.12kWh LiFePO4 battery built for RVs, marine use, camper vans, and off-grid systems that need inverter communication. It replaces lead-acid banks in 48V applications and includes a sealed IP65 case and self-heating for cold-weather charging.

E-E-A-T Intro
Lithium Iron Phosphate (LiFePO4) chemistry sets the HUSKY 2 apart from AGM or flooded lead-acid batteries of similar footprint. The manufacturer data confirms Tier 1 LFP cells, an internal Battery Management System (BMS), self-heating for cold starts, and an IP65-rated enclosure for weather exposure. Inverter communication on this INV variant lets the battery report state-of-charge data directly to compatible inverter systems, which matters for anyone monitoring an off-grid or mobile power setup.
Battery Characteristics
Chemistry: LiFePO4 (Lithium Iron Phosphate). Nominal system voltage: 48V. Rated capacity: 100Ah, totaling 5.12kWh of stored energy. The casing carries an IP65 ingress rating, and the unit includes internal self-heating to support charging in cold conditions. [NEEDS VERIFICATION: specific low-temperature charge cutoff threshold not provided in source data.]
Wiring & Configuration Limits
Manufacturer source data does not specify a maximum series or parallel expansion count for the HUSKY 2 INV. [NEEDS VERIFICATION: series/parallel limits not stated in provided data.] Do not assume compatibility with other BigBattery series/parallel ratings without confirming against the manufacturer's Resources tab documentation before wiring multiple units together.
Pro-Installer Tip
Charging any lithium battery below freezing without cold-weather protection damages cells through lithium plating — a failure mode that is invisible until capacity suddenly drops. The HUSKY 2's self-heating feature is designed to reduce this risk, but confirm the unit has reached its operating temperature before applying a full charge current in sub-freezing conditions. Use a shunt-based battery monitor to track real-time voltage and temperature behavior rather than relying on guesswork. As a professional standard, LiFePO4 chemistry supports 80-100% depth of discharge (DoD) per cycle, unlike lead-acid batteries limited to roughly 50% DoD — plan your usable capacity accordingly.
Key Benefits
- LiFePO4 chemistry offers longer cycle life than flooded or AGM lead-acid at comparable capacity.
- Self-heating supports charging in cold-weather environments.
- IP65 casing rating for exposure to dust and moisture in marine, RV, and utility cart settings.
- Inverter communications on this INV variant for direct state-of-charge reporting to compatible inverters.
- Advanced internal BMS manages cell-level protection.
