This bundle is two B500K expansion batteries supplied in the configuration for the AC500 power station. Each B500K is a 5,120Wh (5.12 kWh) LiFePO4 pack, so the pair roughly doubles what a single-battery AC500 setup carries.
For an RV or off-road camper this is the upgrade that lets a fridge, furnace and electronics run for days without a generator. Bluetti rates the battery at over 4,000 cycles and up to 10 years, says the system can scale to 100 kWh, and lists compatibility with Apex 300, AC300, AC500, AC200L and AC200MAX. It mounts on a wall to save space or rides on a trolley for a movable setup, and it works alongside SolarX 4K and Hub D1.
