Abstract
Techniques are disclosed for supplying positive and negative voltages to electrical components in a system where power demand from the components needing voltage of one polarity is different from the power demand from components needing voltage of the other polarity. At least two batteries of substantially the same capacity are connected in series and used to supply the positive and negative voltages to the system components. In order to permit the batteries to be recharged simultaneously in series without damage to them the interconnection between the batteries and the loads are alternately reversed so that the batteries will discharge at substantially the same rate.
