This disclosure includes novel ways of implementing a power supply that powers a load. A main battery source produces a main battery voltage; each of multiple auxiliary battery sources in a set produces a respective auxiliary battery voltage. A controller initially sets a battery supply voltage to the main battery voltage, the main battery voltage is supplied to a power converter. The controller then monitors a magnitude of the battery supply voltage and adjusts the battery supply voltage supplied to the power converter based on a comparison of the magnitude of the battery supply voltage with respect to a threshold level. The adjusted battery supply voltage is provided from a serial connection of the main battery source and a first auxiliary battery source in the set.
