This kit bundles four BigBattery HUSKY2 batteries with an AIMS pure sine wave inverter and a charger, packaged as a single lead-acid replacement system. BigBattery markets this configuration for 48V applications. Exact per-battery voltage, capacity, and inverter/charger ratings are not specified in the source data for this listing — see the note below for where to find complete documentation.
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 Configuration Matters
BigBattery designates this kit as a lead-acid replacement intended for 48V applications, built around four HUSKY2 batteries paired with an AIMS inverter and charger. The manufacturer lists this system as suitable for Class A, B, and C RVs, camper vans, tow-behind trailers, marine systems, boats and yachts, commercial vehicles, food trucks, and emergency backup uses such as light towers and signs. Confirming the exact wiring configuration (series, parallel, or series-parallel) and each component's rated output against your own electrical load is a step every buyer should take before installation, since the source specifications available to us do not include per-battery voltage, Ah, or inverter/charger wattage figures.
Battery Characteristics
Chemistry: LiFePO4 (Lithium Iron Phosphate) — HUSKY2 is a BigBattery lithium product line. [NEEDS VERIFICATION: capacity in Ah, watt-hours, cycle life, group size, and dimensions are not provided in the source data for this SKU.]
Wiring & Configuration Limits
BigBattery's product description states this kit is "Designed For 48V Applications." The source data does not specify the exact series/parallel wiring diagram for the four HUSKY2 units, nor the BMS-enforced maximum series or parallel count. [NEEDS VERIFICATION: confirm series/parallel configuration and maximum expansion limits with the manufacturer documentation before wiring.]
Do not mix this kit's batteries with lead-acid, AGM, or Gel batteries in the same bank. Do not combine HUSKY2 units of different ages or cycle counts in one string. Standard lead-acid chargers are NOT recommended for lithium packs unless the included charger is confirmed compatible — verify charger specifications in the manufacturer resources before use.
Pro-Installer Tip
Wiring lithium batteries in series or parallel without matching state-of-charge across all four units is the most common cause of premature BMS lockout in multi-battery kits like this one. Before connecting a new HUSKY2 bank, charge each battery individually to full and let it rest, then confirm all four read the same open-circuit voltage. This prevents cell imbalance between packs, which otherwise forces the BMS to shut down the weakest unit under load and shortens the usable life of the whole bank. Use a shunt-based battery monitor on the assembled bank going forward, not just a multimeter at the terminals, so you can track pack-level state of charge over time. Because exact BMS discharge/DoD figures are not listed for HUSKY2 in this source data, treat 80% DoD as a conservative working limit for LiFePO4 until you confirm the manufacturer's rated depth of discharge in the Resources tab.
Key Benefits
- Bundled kit: four HUSKY2 batteries, one AIMS pure sine wave inverter, and one charger sold as a single system — reduces sourcing multiple separate components.
- Marketed as a direct lead-acid replacement, intended to simplify retrofits in existing 48V lead-acid banks.
- Cross-application design: usable across RV, marine, commercial vehicle, and emergency backup power scenarios per manufacturer's stated use cases.

Compatibility & Fitment
This kit is positioned by the manufacturer for: Class A, B, and C RVs, camper vans, tow-behind trailers, marine systems, boats and yachts, commercial vehicles, food trucks, and emergency backup applications including light towers and signs.
This kit is NOT specified as a starter battery application. Do not assume compatibility with a 12V-only load without confirming how the four HUSKY2 units are wired for the stated 48V design. Charging requirements for the included charger (input voltage, amperage, lithium-specific charge profile) are not detailed in this source data — confirm charger compatibility with your lithium bank before first use. Do not substitute a generic lead-acid charger unless the manufacturer documentation confirms it is safe for LiFePO4.
