Product Description

The BigBattery 24V HUSKY 2 INV delivers 5.12 kWh of LiFePO4 storage at 24V (200Ah) for RV, off-grid, and marine systems. The INV model adds inverter communications, letting the battery talk directly to compatible inverters for closed-loop charging and monitoring — your system charges to the battery's actual state instead of guessing from voltage.

Why the 24V HUSKY 2 INV

5.12 kWh from a single battery — 200Ah at 24V, with half the current draw of an equivalent 12V system for the same power
Inverter communications (INV): closed-loop integration with compatible inverters for accurate state-of-charge and coordinated charging
LiFePO4 chemistry — stable lithium iron phosphate cells with a built-in battery management system (BMS) that protects against over-charge, over-discharge, and shorts
Efficient 24V architecture means thinner cabling and less resistive loss than 12V at the same wattage

Who it's for

Larger RVs, boats, and off-grid cabins running 24V electrical systems — or builders stepping up from 12V to run bigger inverters efficiently. The HUSKY 2 line also comes in 12V (400Ah) and 48V (100Ah) versions with the same 5.12 kWh capacity.

Common questions

Why choose 24V over 12V?

Same stored energy, half the current — which means thinner, cheaper cabling, less voltage drop, and better efficiency with mid-size inverters. If your existing system and appliances are 12V, stay with the 12V HUSKY 2 instead.

What does the INV designation mean?

INV models include communication hardware that lets the battery report state-of-charge, temperature, and health directly to compatible inverters — closed-loop charging instead of voltage-based guesswork.

How does LiFePO4 handle cold weather?

It discharges reliably in freezing temperatures, but the BMS restricts charging below freezing to protect the cells — mount the battery in an insulated compartment or heated space for year-round charging.
