The Bluetti B300 Expansion Battery Module is equipped with a LiFePO4 battery with a capacity of 3072 Wh (3500 life cycles). If you want to increase the capacity of your Bluetti Power Station, you can use the B300 Battery Module in combination with the AC300 Power Station (Max. 4), the Bluetti AC200Max (max. 2), AC200P (max. 1), EB200 (max. 1), or the EP500 Pro (max. 2). The AC300 Power Station is designed without an integrated battery, making it work only in combination with the B300 Battery Module. You can also use the B300 Module independently of a Power Station, providing you with flexibility at all times. On the side of the Bluetti B300 Battery Module, there are a USB port, a USB-C port (100W), and a 12V/10A output. This allows you to directly connect all your essential USB and DC devices to the B300 Battery Module.

With the individual 500-watt AC input, the B300 can be charged in combination with the T500 Adapter. Thanks to the built-in MPPT solar input, you can charge the B300 with a power of up to 200W via solar panels. Additionally, you can charge the B300 (together with the Bluetti D050S) in the car using a 12V car charging cable, through a lead-acid battery, or in combination with the AC300.
