To connect, ensure the Anker SOLIX logo on one end of the cable is facing up. Plug it directly into the power station and plug the other end into any port of the expansion battery.
To disconnect, hold the black part of the cable and pull it out.
If you want to connect the power station and the expansion battery, first turn off the main power button off the power station.
Use the included battery-to-host cable to connect the expansion battery to the power station, which can also be used for connections between expansion batteries. Up to six expansion batteries can be connected to the power station.
The expansion battery icon will appear on the power station’s screen when it is successfully connected. The number after the “x” on the screen represents the number of connected expansion batteries. If no icon is displayed, you will have to reconnect both devices as there may be a poor connection.

To disconnect, hold the black part of the cable and pull it out directly.
To ensure the stability and health of each expansion battery, when the power station is connected to multiple expansion batteries, the power of the expansion batteries will automatically balance. This ensures that each battery level remains consistent. It is normal if there is a change in the power of the power station and expansion batteries.
