The purpose of the POWER GOOD signal is a quick acting signal telling the
CPU that the power is going down. The CPU then has enough time to
go to sleep gracefully without damage. It also stops the CPU from starting
with too low a voltage.

In using 3 terminal regulators remember that they need around 2 volts over
the output voltage to be able to function. Considering that, it would be
effecient to use an invertor. Also each part of the battery string would
to be charged at a different current to keep all the cells equally charged.
