1. A method for monitoring the voltage of each of a plurality of cells of a battery pack, said method comprising:

  • monitoring a voltage potential for each of a plurality of cells in a battery pack utilizing a single channel of a battery control unit within the battery pack;

    discontinuing current flow from battery pack when the voltage potential of any cell is determined by the battery control unit to be below a predetermined minimum voltage during discharge of the battery pack; and

    reducing the voltage potential stored in any one or more of the cells when a voltage differential between the respective one or more cells and any other one of the cells having a lesser voltage potential is determined by the battery control unit to exceed a predetermined maximum differential during charging of the battery pack.
