Battery pack for transportation and operation

A battery pack comprising:

• a housing;
• a plurality of cells disposed in said housing and electrically coupled to provide a storage capacity with a lithium content, said plurality of cells being separated into a first battery including a plurality of said cells permanently connected and a second battery including a plurality of said cells permanently connected;
• and
• said plurality of cells having at least three battery contacts exposed to an exterior of said housing, wherein said first battery is disposed in said housing and including a first plurality of cells connected in series and said second battery disposed in said housing and including a second plurality of cells connected in series, wherein said first battery and second battery are operable in a storage mode and a use mode, said storage mode including isolating said first plurality of cells from said second plurality of cells, said use mode including electrically connecting said first plurality of cells to said second plurality of cells and defining a voltage and a storage capacity for the battery pack, and said plurality of cells provides 36 volts.
