Choose your version. Bluetti sells the B500K in three versions, one for each host power station: Apex 300, AC200L / AC300 and AC500. Each has its own Bluetti part number and price, so pick the one that matches your station in the Compatible with menu.
The B500K is BLUETTI's large expansion battery — 5,120Wh in a single unit, for full-time off-grid use or whole-rig backup. Like the B300K it is an expansion battery rather than a standalone station, and must be connected to a compatible BLUETTI power station to deliver household AC. Its modular design means you can add storage over time without replacing the system you already own.
