Doohhhh!   in my best Homer Simpson voice...
They typically read 24-26 volts.
That is good news, I am sure that your are right and there should be some off
the shelf components to make this easier...

Is it really a "28V" battery?  How many cells does it have?  I have a
feeling that they're called 28V batteries because it's used in a 28V
electrical system, but the rest of the non-aviation world calls them
24V.  If that's the case, you'll be able to use stuff intended for
marine or heavy-duty truck use, which is cheaper.
