PROBLEM TO BE SOLVED: To provide a battery pack capable of easily increasing and decreasing battery capacity without damaging the efficiency of usage and productivity, and to provide a cover for connecting a battery pack. SOLUTION: The battery pack 1 is constituted by housing a cell 11 and a circuit board 16 in an outer packaging case 10, and has electrodes 12, 13 of the cell 11 and battery terminals 17, 18 electrically connected to the electrodes 12, 13. The battery pack 1 is equipped with connectors 19, 20 connectable from the outside of the outer packaging case 10 and electrically connected to the battery terminal 17, and connectors 21, 22 connectable from the outside of the outer packaging case 10 and electrically connected to the battery terminal 18. At least two battery packs 1 can electrically be connected in parallel through the connectors 19, 20 and the connectors 21, 22. COPYRIGHT: (C)2006,JPO&NCIPI
