It comes with the P090A battery expansion cable, which links it to an AC300, AC200L or AC200MAX, or to another B300K.\u003c\/p\u003e\n\u003cp\u003eIt's for AC300 and AC200L owners who want longer runtime for home backup, off-grid living or long stays away from the grid without buying a second power station. BLUETTI also lists the AC500 as a host when you add the separately sold P090D to P150D cable.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cbr\u003e\n\u003ch3\u003eBLUETTI B300K Expansion Battery Features\u003c\/h3\u003e\n\u003ch4\u003e2,764.8 Wh in One Pack\u003c\/h4\u003e\n\u003cp\u003eEach B300K stores 2,764.8 Wh at 51.2V and 54Ah using LFP cells.

The AC200L and AC200MAX each take up to 2 units for 5,529.6 Wh, and the AC500 takes up to 6 units for 16,588.8 Wh. The AC300 can also run B300K and B300 expansion batteries together using P090A cables.\u003c\/p\u003e\n\u003ch4\u003eCharges Through Your Power Station\u003c\/h4\u003e\n\u003cp\u003eThe B300K charges through the power station it's connected to. On an AC300 or AC500, it charges from 5% to 80% in about 45 minutes. When the combined system charges from AC power or solar panels, the B300K turns on automatically.\u003c\/p\u003e\n\u003ch4\u003eLocking P090A Expansion Cable\u003c\/h4\u003e\n\u003cp\u003eThe included P090A cable is 31.49 in (800 mm) long. Press it down into the port and push to lock it in place. If the cable isn't locked, the power button flashes twice, pauses for 4 seconds and repeats, so you know to check the connection.\u003c\/p\u003e\n\u003ch4\u003eApp Monitoring and Updates\u003c\/h4\u003e\n\u003cp\u003eWith the B300K connected to your power station, you can check its battery level and update its firmware in the BLUETTI app under Settings, then Firmware Upgrade.\u003c\/p\u003e\n\u003ch4\u003eBuilt-In USB-A Port\u003c\/h4\u003e\n\u003cp\u003eA USB-A port on the front delivers 5V at 2.4A, up to 12W, so you can charge small USB devices directly from the pack.\u003c\/p\u003e\n\u003ch4\u003eBattery Level at a Glance\u003c\/h4\u003e\n\u003cp\u003eFive LED indicators show the state of charge, with each lit light representing 20%.

Connecting to an AC500 requires the P090D to P150D battery expansion cable, which isn't included. On an AC500, the B300K can run together with B300 and B300S packs using the cables BLUETTI specifies for each pairing.\u003c\/p\u003e\n\u003ch4\u003eTemperature and Storage\u003c\/h4\u003e\n\u003cp\u003eCharge the B300K between 32°F and 104°F (0°C to 40°C), with 59°F to 86°F (15°C to 30°C) recommended, and discharge it between -4°F and 104°F (-20°C to 40°C). Before storage, charge it to 60% to 80% and run a full cycle every 6 months. For storage longer than 6 months, keep it at 40% to 60% and cycle it every 3 months.
