1. An apparatus, comprising:
a first circuit, wherein the first circuit contains a first load, wherein a first battery is associated with the first circuit, and further wherein the first load comprises an electric motor of an electric vehicle or a hybrid vehicle;
a second circuit, wherein the second circuit contains a second load, wherein the second load draws current from a second battery when the first load is not operating or is non-operational;
a first switch, wherein the first switch is capable of disconnecting the first battery from the first circuit;
a second switch, wherein the second switch is capable of connecting the first battery to the first circuit, wherein the first switch and the second switch are connected in series;
at least one recharger, wherein the at least one recharger recharges the first battery and the second battery when the first load is operating; and
a third load, wherein the third load is connected between the first circuit and a third circuit, wherein the third circuit contains the second battery, and further wherein the third load generates a circuit stabilizing voltage drop when respective voltage levels of the first battery and the second battery are not equal.
