1. A vehicle electrical system for a vehicle comprising:
a power source;
a first low-voltage bus;
a first power-distribution box electrically connected to the power source and to the first low-voltage bus and positioned to control electrical flow from the power source to the first low-voltage bus;
a first low-voltage battery electrically connected to the first power-distribution box and arranged to supply electricity to the first low-voltage bus via the first power-distribution box;
a second low-voltage bus;
a second power-distribution box electrically connected to the power source and to the second low-voltage bus and positioned to control electrical flow from the power source to the second low-voltage bus; and
