Suppose you have a device (HF transceiver) that requires 11.7V to 15.8V
DC to run and you want to run it from lead acid batteries. If you use a
12V (6 cell) battery, a large part of the battery life will be to low of
a voltage to run the radio, especially when you take into account the
voltage drop in the power wire. A 7 cell battery would be great but
I've never seen one and I can't find single cells to make my own pack
that aren't gigantic.
So it seems to me the best solution is a DC to DC converter. What I am
wondering is would it be easier to step up the voltage of a 12V battery
when it drops below say 12V or step down from 24V? Depending on the
radio I use, I will need between 20 to 40A peek, average current should
be much less though.
