The Big Battery NEXUS 2 is a 48V, 16kWh LiFePO4 floor-standing battery for whole-home backup, larger off-grid cabins and light commercial storage. It packs a full 16kWh into one block with an integrated smart BMS handling over/under-voltage, over-current, temperature and cell balancing, so you avoid paralleling several smaller packs. It is parallel-ready up to 15 units and works with most 48V inverter/chargers. Against rack-style DIY batteries it trades modularity for plug-and-power simplicity; against smaller server-rack packs it offers far more runtime per unit.

The Big Battery 48V 16kWh NEXUS 2 is a floor-standing LiFePO4 (LFP) battery for whole-home backup, larger off-grid cabins, and 48V solar systems. It stores 16.08 kWh in a single unit, so fewer smaller batteries need to be paralleled.
It combines LFP cells, a smart BMS, and a rugged enclosure rated for indoor or outdoor use. The built-in BMS handles over-voltage and under-voltage protection, over-current protection, temperature protection, and cell balancing. LiFePO4 chemistry offers long cycle life and low maintenance compared with lead-acid.
The battery is modular. Up to 15 batteries can be paralleled to build larger banks. It works with most 48V inverter/chargers and suits loads such as pumps, mini-splits, compressors, and shop tools.
