The assembled battery module includes a battery body in which the cells are stacked over a bottom plate The swell limiter is located on the opposite side of the assembled battery module than the bottom plate is. The swell limiter is separate from the battery body when any of the cells is not swelling and works to make physical contact with the battery body when any of the cells has swollen to suppress swelling of the cell.
