This kit bundles three BigBattery HUSKY2 12V LiFePO4 batteries with an AIMS pure sine wave inverter and a 12V charger, packaged for 48V-capable off-grid and mobile power setups. It's built for RVs, campers, marine systems, tow-behind trailers, and similar applications where lead-acid is being phased out.
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 Kit
Lead-acid battery banks in RVs, boats, and commercial vehicles lose usable capacity as they age, and they add weight you don't need to carry. This kit replaces that setup with LiFePO4 chemistry across three HUSKY2 units, paired with an AIMS inverter/charger so the system is ready to install rather than pieced together from separate vendors. BigBattery lists this configuration as designed for 48V applications, which points to the three HUSKY2 units being wired in series as part of a larger series/parallel bank architecture — confirm the exact wiring diagram in the manufacturer documentation before you connect anything.

Wiring & Configuration Limits
BigBattery designates this kit "for 48V applications," meaning the three HUSKY2 batteries are intended to be combined to reach 48V nominal — consistent with series wiring of 12V units. The manufacturer resource tab is the authoritative source for the exact series/parallel wiring diagram, maximum string count, and BMS communication requirements for this specific kit; that detail is not present in this listing's source data.
NOT confirmed for this kit: Maximum parallel string count, BMS max continuous discharge/charge amps, and peak discharge amps are not stated in the source data. Do not assume these values — check the Resources tab before wiring.
Pro-Installer Tip
Series-wiring lithium batteries to hit a target voltage (like 48V from three or four 12V units) only works safely when every battery in the string carries a matched BMS and a matched state of charge before you connect them. Mismatched charge levels across a series string cause the BMS on the lowest-charged unit to hit its low-voltage cutoff early, which can trigger a lockout and leave the whole bank offline. Charge each HUSKY2 unit independently to a matched voltage before assembling the series string, and verify balance afterward with a shunt-based battery monitor rather than relying on a single pack's built-in display. LiFePO4 chemistry tolerates 80-100% depth of discharge, but a string-level lockout from imbalance will make that DoD irrelevant if the bank won't power on.
Key Benefits
- Lithium Iron Phosphate chemistry as a stated lead-acid replacement for 48V-capable applications.
- Bundled AIMS pure sine wave inverter and 12V/110V AC charger — one kit instead of separately sourced components.
- Pre-included ring-terminal and 4AWG ring-to-ring cabling for interconnects.
- Applicable across RV classes A/B/C, camper vans, tow-behind trailers, marine/boat/yacht systems, commercial vehicles, food trucks, and emergency backup use (light towers and signs) per manufacturer use-case list.

Compatibility & Fitment
Designed 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 including light towers and signs, per the manufacturer's listed applications. Intended as a lead-acid replacement in 48V-capable systems.
NOT confirmed / NOT included: This kit's source data does not confirm compatibility as a starter/cranking battery application — do not use LiFePO4 house batteries of this type for engine starting unless the manufacturer explicitly states otherwise. Standard lead-acid chargers are not recommended for LiFePO4 packs unless the manufacturer confirms compatibility; use the included AIMS charger or a charger rated for LiFePO4 charge profiles. Maximum series/parallel expansion beyond the 3-unit kit configuration is not specified in the source data — do not assume additional units can be added without checking manufacturer documentation.

FAQ
What chemistry are the HUSKY2 batteries in this kit?
They are LiFePO4 (Lithium Iron Phosphate) batteries, rated at 12V nominal per unit, with three units included in this kit.
Can I use a standard lead-acid charger with this kit?
No. Standard lead-acid chargers are not recommended for LiFePO4 batteries unless the manufacturer confirms compatibility. Use the included AIMS 12V charger or a charger rated for LiFePO4 charge profiles.
Is this kit designed for 48V systems?
Yes. BigBattery designates this kit for 48V applications, indicating the three HUSKY2 units are intended to be wired together to reach that system voltage. Confirm the exact series/parallel wiring diagram in the manufacturer's Resources tab before installation.
What is included in the kit?
Three HUSKY2 12V LiFePO4 batteries, one AIMS pure sine wave inverter, one 12V AC charger, and ring-terminal / 4AWG ring-to-ring interconnect cables.
Can this kit be used as a starter battery for an engine?
This is not confirmed as a starter/cranking battery application in the manufacturer data. Treat it as a house/auxiliary power bank unless the manufacturer states otherwise.
