Beschreibung
Zusammenfassung:	The invention provides a storage battery system which can balance the voltage among a plurality of storage battery blocks according to a plurality of rated voltages. The battery system includes a battery pack, a first electric working machine, and a second electric working machine. The battery pack includes a plurality of battery blocks and a terminal portion. The terminal part is provided with atleast one parallel connection terminal and a plurality of output terminals. When the first connection terminal is connected to at least one of the plurality of output terminals and when the connection target is not connected to any one of the plurality of output terminals, the at least one parallel connection terminal is connected to at least one of the plurality of output terminals. The plurality of battery blocks are connected in parallel, and when the second connection terminal and the plurality of output terminals are respectively connected, the plurality of battery blocks are separated from each other and indepe
