This is a bundled off-grid power kit: four BigBattery HUSKY 2 batteries wired for a 48V system, paired with an EG4 12K off-grid inverter. It is built for off-grid systems, emergency backup, and lead-acid replacement applications — including Class A, B, and C RVs, camper vans, food trucks, commercial vehicles, and other mobile power setups.
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.
What This Kit Is Built For
Off-grid battery kits live and die on two things: the chemistry doing the storage work and the honesty of the specs behind it. This kit combines four HUSKY 2 batteries into a 48V bank with an EG4 12K inverter to run the load. As specialists who work with off-grid, RV, marine, and home storage batteries daily, we document what the manufacturer provided below — and flag anything that isn't in the source data rather than guess at it.
Battery Characteristics
Chemistry: LiFePO4 (Lithium Iron Phosphate) [NEEDS VERIFICATION] — confirm chemistry designation on the HUSKY 2 battery datasheet in the Resources tab.
Configuration: Four HUSKY 2 battery units arranged for a 48V bank, sold as a kit with an EG4 12K inverter. Individual per-unit voltage, Ah capacity, group size, dimensions, weight, cycle life, and BMS discharge/charge limits were not included in the manufacturer data provided for this listing.

Wiring & Configuration Limits
This kit is described by the manufacturer as designed for 48V applications, using four HUSKY 2 units together. The specific series/parallel wiring instructions for the four batteries (e.g., how many in series vs. parallel to reach 48V), maximum expandable series/parallel limits beyond this kit, and inverter input voltage/amperage limits were not provided in the source data. [NEEDS VERIFICATION] Do not assume standard series/parallel ratios — confirm exact wiring configuration against the manufacturer manual in the Resources tab before connecting.
NOT confirmed compatible with 12V or 24V system configurations based on the data provided — this kit is stated only for 48V applications. NOT to be mixed with lead-acid, AGM, or Gel batteries in the same bank. NOT to be paired with batteries of different ages or differing cycle counts in the same string.
Pro-Installer Tip
Mismatched state-of-charge across the four HUSKY 2 units before first parallel/series connection is a common source of early BMS lockout or cell imbalance in multi-unit lithium kits. Charge each battery to a matching voltage individually before connecting the bank, then verify balance with a shunt-based battery monitor rather than relying on a dashboard percentage. For lithium chemistry, plan your daily cycling around an 80–100% depth of discharge target rather than the 50% DoD ceiling used for lead-acid — but only once the manufacturer's confirmed BMS discharge limits (see Resources tab) are in hand, since those numbers govern your safe continuous draw.
Key Benefits
- Pre-configured 48V bank of four HUSKY 2 units paired with an EG4 12K inverter — reduces the guesswork of sourcing batteries and inverter separately.
- Positioned by the manufacturer as a lead-acid replacement for off-grid systems and emergency backup.
- Suited to mobile applications: Class A/B/C RVs, camper vans, food trucks, and commercial vehicles.
Cycle life, weight savings versus lead-acid, and specific BMS feature details were not included in the manufacturer data for this kit. [NEEDS VERIFICATION]
