BLUETTI B300K2 2,764.8Wh Expansion Battery with CA90 Cable

Add 2,764.8Wh of nominal LiFePO4 storage to a compatible BLUETTI power system. This exact package includes the CA90 battery expansion cable.

Choose the correct configuration

Select this CA90 package for an approved Apex 300 or compatible battery-to-battery connection. Confirm the receiving model and connection arrangement in its manual. P090A and the optional P090D-to-P150D cable are separate cable types; this package does not include them.

Before you buy

This is an expansion battery, not a complete AC power station. A compatible power station and correct connection cable are required for AC loads. Capacity increases available energy, not the connected station’s inverter output rating.
