A battery pack device includes: a support body that supports a plurality of batteries arranged at least in one row; a coupling member that is provided on the support body and cooperate with another coupling member formed on a support body of another battery block to couple the battery blocks to each other; and a connection electrode that connects between electrodes exposed from the plurality of batteries. The coupling member is provided so as to locate at the same position after the battery block is rotated in the same plane. Further, the battery pack device is configured to switch between serial connection and parallel connection between the battery blocks according to whether the battery block is rotated or not.
