1. A multiple voltage battery power supply system for operating a plurality of vehicle electrical loads at selected voltage output levels, the system comprising:

  • a first power block providing a first voltage output for operating vehicle electrical loads at a first voltage level;

    a second power block connected in series with the first power block and substantially electrically similar to the first power block, the second power block providing a second voltage output independent from the first voltage output for operating vehicle electrical loads at a second voltage level;

    wherein each power block independently maintains a substantially constant voltage at each corresponding voltage output and the series combination of each power block maintains a substantially constant third voltage output across both the first and second power blocks for operating vehicle loads at a third voltage level.
