The Bluetti B300S 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 B300S Battery Module in combination with AC500 Power Station (Max.6). The AC500 Power Station was developed without an integrated battery, so the AC500 only works in combination with the B300S Battery Module. It is also possible to use the B300S Module separately from a power station, so you are always flexible. The side of the Bluetti B300S 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 B300S Battery Module.
The B300S 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 B300S with a maximum of 500W power via solar panels. In addition, you can charge the B300S (together with the Bluetti D050S) in the car with a 12V car charging cable, via a lead-acid battery or in combination with the AC500.
