The expansion battery has two SDC ports, arranged vertically.
The upper SDC port on the expansion battery must be connected to the SDC port of the power station or the lower SDC port of another expansion battery.
The lower SDC port on the expansion battery can be used to connect a Super Fast Charger or another expansion battery. However, the SDC port of the expansion battery cannot connect to the DJI Power Dongle, which must be connected to the power station.
