Description
Overview
The 24V HUSKY 2 packs 5.12kWh of Tier 1 LiFePO4 cells into one IP65 / NEMA 4X rated battery. It’s BigBattery’s most energy-dense 24V battery.
This INV version includes CANBus and RS485 inverter communications. A smart BMS balances the cells automatically, a self-heating function keeps it charging through winter, and the hardened shell resists vibration. An LED meter shows state of charge, with an external meter and mobile app as options.
Up to 16 connect in parallel (they’re not designed for series wiring). BigBattery notes this battery is for energy storage, not for powering vehicle drive systems.
