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, it is possible to use this 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 the only Bluetti power station developed without an integrated battery, so the AC300 only works in combination with the B300 Battery Module. It is also possible to use the B300 Module separately from a power station, so you are always flexible. The side of the Bluetti B300 Battery Module is equipped with a USB port, USB-C (100W) port and a 12V/10A output. That means you can connect all your essential USB and DC devices directly to the B300 Battery Module.
The B300 can be charged in combination with the T500 Adapter via the individual AC input of 500 watts. Thanks to the built-in MPPT solar input, you can charge the B300 with a maximum of 200W power via solar panels. In addition, you can charge the B300 (together with the Bluetti D050S) in the car with a 12V car charging cable, via a lead battery or in combination with the AC300.
