Bob, for those of us who have certified airplanes and want active
notification of low voltage, EI sells a cheap ($285) voice annunciator
that will say "Check Bus Voltage" in a soft female voice right into your
headset if the voltage drops below 13V, without being hooked to anything
but power. (She'll say 16 other things, too, if hooked up to various
instruments' alarm outputs). It certainly always gets my attention when I
chop the power on approach and switch on the landing light and she reminds
me that I'm now sucking some battery power.
Also there may be some people who think the annual battery condition test
is a complicated process that requires construction of devices with light
bulbs and timers and things.

Zeftronics makes a line of modern voltage regulators to replace the
horrible Delco Remy mechanical gizmo from the 60's with a nice device that
features OV and LV lights as well as Overvoltage protection using an
external relay.
Those are just some of the things I have discovered that hopefully some of
the certified people on this list might find useful.

As you've illustrated, there are several ways
to skin this cat . . . have a plan-b. It does
take some consideration and PERIODIC verification
but there are a variety of ways to do it. Thanks
for sharing this with us!
