1. An electrical power system comprising:
a connection to a power source;
two differential lines along which power from the power source travels to a load zone;
a first energy storage unit;
a second energy storage unit;
a booster energy storage unit with one or more chemistries;
one or more switches; and
a controller configured to:
configure the one or more switches to cause the first energy storage unit to be in series with the booster energy storage unit between the two differential lines; and
based on a determination that a voltage drop across the first energy storage unit is less than a voltage drop across the second energy storage unit, configure the one or more switches to cause the second energy storage unit to be in series with the booster energy storage unit between the two differential lines.
