A rechargeable battery pack includes a plurality of cell modules connected to each other via bus bars, each cell module including a plurality unit cells with electrode terminals connected to the bus bars, a plurality of spacers between the cell modules, first and second plates coupled to opposite sides of the spacers, the first and second plates being configured to support the cell modules therebetween, and flow paths between the unit cells in a length direction of the unit cells, the flow paths being between side surfaces of the spacers and side surfaces of the unit cells, and being further partially set by sides of the bus bars.

Rechargeable battery pack

A battery pack includes a first battery with a first capacity, a second battery with a second capacity less than the first capacity, and a variable resistor. The second battery has a larger maximum discharge current than the first battery. The variable resistor circuit limits the discharge current of the first battery to a predetermined limit current value.
