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.
