1. An article of manufacture including a data storage medium, said data storage medium including a set of machine-readable instructions that are executable by a processing device to implement an algorithm, said algorithm comprising the steps of:

  • detecting when a first energy capacity of a first battery pack falls below a lower threshold;

    comparing the first energy capacity to a second energy capacity of a second battery pack; and

    , if the first energy capacity is less than the second energy capacity, directing a charging circuit to charge the first battery pack to a first maximum energy capacity.
