Abstract: A linked battery module includes a first battery module and a second battery module having a same configuration. The first battery module includes: a battery stack that includes rectangular batteries stacked in a row in a thickness direction; a restraint member on one side that restrains one side, in a Y direction, of the battery stack; a restraint member on the other side that restrains the other side, in the Y direction, of the battery stack; an end plate on one side that restrains one side, in an X direction, of the battery stack; and an end plate on the other side that restrains the other side, in the X direction, of the battery stack. A linking unit links the end plate on one side of the first battery module to the end plate on the other side of the second battery module.
