1. A compact integrated battery pack for a hybrid vehicle, the battery pack comprising:
a housing;
a plurality of battery cells disposed within the housing and configured to collectively output a primary voltage for powering an electric motor of the hybrid vehicle;
a direct current (DC) to DC converter circuit disposed within the housing and configured to step-down the primary voltage to a secondary voltage for powering low voltage components of the hybrid vehicle;
a control circuit disposed within the housing and configured to control (i) recharging of the plurality of battery cells, (ii) output of the primary voltage, and (iii) output of the secondary voltage; and
an integrated cooling system disposed within the housing and configured to cool the battery pack.
