ABSTRACT:
A battery pack is comprised of multiple lithium cells electrically connected in series. The voltage mismatch between the multiple lithium cells of the battery pack is balanced by utilization of an operational amplifier in conjunction with multiple series resistors having equal resistance values. The problems inherent with utilizing multiple lithium type cells in a series configuration is thereby eliminated. The multicelled battery pack may be charged in any desired fashion.
