This is a paired system: two BigBattery HUSKY 2 48V LiFePO4 batteries and an EG4 6K off-grid inverter, sold together as one kit. It is built for off-grid setups, emergency backup, and mobile power applications where you need a battery bank and an inverter that are matched from the start.

Field Notes on This Kit
Off-grid systems fail more often from mismatched components than from bad batteries. Pairing a battery bank with an inverter that was never tested together leaves you guessing at charge rates, communication protocols, and surge handling. This kit removes that guesswork: two HUSKY 2 batteries wired for 48V, connected to an EG4 6K inverter, as a single purchasable unit under SKU K0705-V.
Battery Characteristics
Chemistry: LiFePO4 (Lithium Iron Phosphate). This kit includes two HUSKY 2 batteries at 48V nominal configuration, combining for a stated total capacity of 10.24kWh. LiFePO4 is used here rather than lead-acid, AGM, or Gel — the manufacturer positions this kit as a lead-acid replacement for off-grid systems.
[NEEDS VERIFICATION]: Individual HUSKY 2 battery Ah rating, BMS max continuous discharge/charge amps, peak discharge amps, cycle life, operating temperature range, weight, and dimensions are not stated in the source data for this listing.
[NEEDS VERIFICATION]: Low-temperature charging protection (cold weather disconnect or internal heating) is not specified in the source data for this kit.
Wiring & Configuration Limits
This kit ships pre-configured as two HUSKY 2 batteries for 48V operation, paired with one EG4 6K inverter. The manufacturer data provided does not state additional series or parallel expansion limits beyond this factory configuration.
NOT confirmed for series stacking beyond the included 2-battery configuration based on available data. NOT a starter battery system. NOT intended for automotive cranking applications. [NEEDS VERIFICATION]: Maximum parallel expansion limit for adding further HUSKY 2 units to this bank.
Pro-Installer Tip
Lithium banks built from multiple battery units are vulnerable to cell imbalance if one unit is charged or discharged independently of its pair. Always bring both HUSKY 2 units online together and let the inverter's charge controller manage them as one bank rather than cycling them separately. This prevents one unit's BMS from drifting out of sync with the other, which can trigger a BMS lockout on the weaker unit over time. Verify balance with a shunt-based battery monitor rather than relying on inverter display estimates alone. As a professional standard, plan discharge depth in the 80-100% DoD range typical for LiFePO4, but confirm the exact BMS cutoff for this HUSKY 2 configuration before setting inverter low-voltage disconnect thresholds.
