Todd,
I'd second Allan's comments. The battery capacity meters from ETA are
probably the best deal you're going to find if you're trying to shave some
bucks off the cost of a Tri-met or E-Meter. I have a lot of experience
with the "low-cost" general purpose digital panel meters, and most of them
have +5V or +9V power inputs - they're intended to be designed into an
instrument, not for use as a system-level component. By the time you get
to process meters with 12-48 VDC power and signal inputs, self-contained in
a protective case, you're up in the price range of the standard RE
monitoring instruments which do quite a bit more. At least that's what
I've found in my travels.
