BLUETTI B300K 2764.8Wh Power Station Expansion Battery

The BLUETTI B300K is a 2,764.8Wh (51.2V, 54Ah) expansion battery that adds capacity to BLUETTI power stations, for home backup during power outages and for off-grid use outdoors. It works with the AC200L, AC200MAX, AC300, AC500 and Apex 300, and several B300K units can be linked to build a larger energy setup.

Square LiFePO4 cells keep 80% of their capacity after more than 6,000 cycles, while AI-BMS, an aluminum casing and a cooling fan keep operation safe. With an AC300 or AC500 the battery charges to 80% in 45 minutes, and a USB-A port lets you charge a phone or tablet even without a power station.
