摘要： 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.
