1. A rechargeable battery pack comprising:
a plurality of unit cells for forming a rechargeable battery by providing an electrode assembly to a pouch wherein the pouch defines a terrace and the terrace includes a vertical unit that is disposed on the terrace and that is disposed closely between a terrace of one unit cell and a terrace of another unit cell from among neighboring units cells and wherein the vertical unit is formed to have a length that is less than a width of a terrace that is set in a direction in which the lead tab is drawn out of the terrace and wherein the vertical unit extends in a first direction; a protection circuit module electrically connected to the unit cells; and a connector connected to the protection circuit module;
wherein the protection circuit module includes:a serial protection circuit for connecting the unit cells in series, anda parallel protection circuit for connecting the unit cells in parallel wherein the protection circuit module further includes a switching unit for selectively connecting the serial protection circuit and the parallel protection circuit to the connector and wherein the switching unit is a manual switching unit that is positioned on an exposed surface of the protection circuit module mounted adjacent the vertical unit so as to be interposed between the serial protection circuit and the parallel protection circuit and so as to be aligned with the vertical unit in the first direction.
