## Long description

The Bluetti B300K 2764.8 Wh Lithium Iron Phosphate Black is an external battery module designed to expand runtime for compatible Bluetti power stations. It uses Lithium Iron Phosphate (LiFePO4) cell chemistry to provide stable voltage output, high cycle life and predictable performance. With a nominal voltage of 51.2 V and a usable energy capacity of 2764.8 Wh, the B300K is intended as an add-on energy reservoir for selected Bluetti systems, offering compact dimensions (525 mm × 327 mm × 209 mm) that simplify placement and transport.
Advantages
The LiFePO4 construction delivers extended cycle life and thermal stability compared with many other lithium chemistries, helping the battery retain capacity over many charge/discharge cycles. Its large 2764.8 Wh capacity increases the available run time for appliances and devices connected to a compatible Bluetti station. Built-in protections guard against common electrical faults such as overcharge, over-discharge and short circuit, while the standardized 51.2 V interface enables seamless integration with supported Bluetti models.
