Looking for a 24v battery charger; recommendations?
Two tasks: charging & maintaining
Does one charger do both well?

Is your battery a "real" 24V device or a pair
of 12s in series? 24V hardware is rare compared
to 12V stuff. In fact, I'm not aware of any
24 charger/maintainers but I'm sure they're out
there. A Google search is the place to start.
If you have a pair of 12s, consider a pair of
Battery Tender like:

http://www.aeroelectric.com/Pictures/Tools/Battery_Chargers/Battery_Tender_Jr.jpg
I've found these "in the wild" for a little
as $29 plus shipping. They recharge like this:

You'll find a LOT of 24v battery service products
but you'll not too that their prices are not
nearly as attractive as the "wall wart" style
tenders.
Know too that Schumacher products sold at Wall
Mart are now "smart chargers". See
http://www.aeroelectric.com/Pictures/Tools/Battery_Chargers/Schumacher_WM-1562.jpg
and recharge like this:

Their smallest models are on the order of $20
each and you don't need to pay shipping

We're using 2 Concord RG24-15 (24v,13.6AH) batteries in a Z14-FADEC system.
Our desire is to charge and maintain the main "A" battery via the ground
power plug.
What issues are there with using two 12v chargers in series?
We already have a B-D 12v charger with the following details:
110 Amp Engine Start - 40 Amp / 20 Amp / 10 Amp / 4 Amp Continuous Charge
Rates - Smart Battery Charger™
Model # VEC1093DBD
3 stage, automatic, high-frequency charging technology
Microprocessor control digital diagnostics & fault codes
Spark-resistant reverse hook-up & overcharge protection
Patented vehicle alternator check & engine start feature
Automatic float mode monitoring

Not practical. A 'smart' charger needs to see the
battery that it's chartered to manage. When you add
another charger in series, all bets for performance
are off.
I can sketch you the circuit for a 24v "tender"
if you wanted to build one.
