This is a bundled off-grid power kit: one BigBattery HUSKY 2 48V lithium battery paired with a Victron 48V MultiPlus-II 120V 3000W Inverter/Charger. It is built for buyers who want battery and inverter/charger sized together as one system rather than sourced separately.
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
Pairing a lithium battery bank with an inverter/charger that is not matched for load, charge current, or communication protocol is one of the more common mistakes in off-grid builds. This kit removes that guesswork by bundling the HUSKY 2 48V battery with a Victron MultiPlus-II 120V 3000W unit as a single purchase. The listed capacity for this kit is 5.12kWh. Beyond that headline figure, the manufacturer source page provided for this listing did not include a detailed specification breakdown (cell chemistry confirmation, Ah rating, cycle life, BMS discharge/charge limits, dimensions, weight, or terminal type) beyond what's noted below — see the flags in the Warnings section.
Battery Characteristics
- Chemistry: LiFePO4 (Lithium Iron Phosphate) [NEEDS VERIFICATION] — the manufacturer name "HUSKY 2" and BigBattery's product family are consistent with LiFePO4, but this was not explicitly restated in the supplied source text and should be confirmed against the Resources tab.
- Nominal system voltage: 48V
- Total usable energy for this kit: 5.12kWh
- Configuration: 1X KIT (single battery unit paired with one inverter/charger)
Wiring & Configuration Limits
This listing is sold as a fixed 1X kit: one HUSKY 2 48V battery plus one Victron MultiPlus-II 3000W inverter/charger. Series/parallel expansion limits (maximum number of HUSKY 2 units in parallel, or series stacking for higher voltage) were not provided in the source data for this SKU. Do not assume expansion capability beyond what is confirmed in the manufacturer documentation. Confirm exact expansion limits, cabling requirements, and communication cable compatibility (Victron VE.Bus, VE.Direct, or Cerbo GX networking) via the Resources tab before adding additional batteries or inverters to this system.
Pro-Installer Tip
Mismatched charge parameters between a lithium battery and its inverter/charger are a leading cause of premature BMS lockout. When commissioning a MultiPlus-II with any lithium bank, do not rely on the inverter's default lead-acid charge algorithm — this can overcharge or undercharge the pack and accelerate cell imbalance over repeated cycles. Set the charge voltage and current limits according to the battery manufacturer's specification sheet, and use a shunt-based battery monitor (such as a Victron BMV or SmartShunt) to track real state-of-charge rather than relying on inverter-estimated SoC. For LiFePO4 packs, plan cycling around an 80-100% depth of discharge as the professional standard, and verify this specific figure against the manufacturer documentation for the HUSKY 2 before finalizing your system's daily discharge routine.
Key Benefits
- Battery and inverter/charger pre-matched as a single kit, reducing compatibility guesswork for a 48V off-grid, RV, or back-up power build.
- Victron MultiPlus-II provides combined inverter and charger functionality (120V AC output, 3000W rating) in one unit.
- 5.12kWh of usable energy sized for off-grid, RV, or back-up applications where whole-home or whole-rig capacity is not required.

Compatibility & Fitment
- Includes: one HUSKY 2 48V battery and one Victron 48V MultiPlus-II 120V 3000W Inverter/Charger, sold together as kit K0137.
- NOT confirmed to include: mounting hardware, communication/network cables (VE.Bus, VE.Direct, or Cerbo GX cabling), battery cables, breakers, or a Cerbo GX display unit — these were shown as separate reference images in the source material and are NOT explicitly stated as included. Confirm exact contents via the Resources tab before ordering.
- NOT for use as a starter/cranking battery.
- Standard lead-acid charge profiles are NOT recommended for this lithium battery; the MultiPlus-II charge settings must be configured for lithium chemistry.
- Series/parallel expansion beyond the 1X configuration sold here is NOT confirmed by the supplied data — do not wire additional units together without verifying limits in the manufacturer documentation.
