1. A method of operating a battery pack, the method comprising:
obtaining voltages of batteries of the battery pack, the battery pack comprising a plurality of the batteries connected to a circuit;
obtaining an output current to be output from the battery pack;
selecting a subset of the batteries capable collectively of providing the output current, the subset comprising one or more selected batteries selected from among the plurality of the batteries, the subset having a subset voltage being substantially similar to a voltage of each of the selected batteries, the subset selected such that the selected batteries have substantially similar voltages and the subset voltage is maximized; and
drawing the output current from the subset of the batteries.
