Hi sageworksinc-ga 

I have found what I think is a very good web site with instructions on
how to build a battery charger. The site is
http://www.angelfire.com/electronic/hayles/charge1.html.
It has detailed instruction on how to build the charger together with diagrams.
However being no expert in the field I do not know if these
instruction are detailed enough for you to be able to accomplish the
task. Therefore cannot really say if this would be anough to answer
your question or not. Also you said that you are interested in a 24V
charger and from the instruction I do not understand if  by increasing
the VAC input we can reach the 24V you require.
I sent an email to owner of the page about that and I'm waiting for his answer.
Can you please let me know if this is what you are looking for or if I
need to keep searching for an answer

There are a lot of important specifications omitted, such as battery
capacity, type, charge rate, etc. One quick-and-dirty approach would
be to use two 12 volt chargers (which are much more readily available)
in series to charge yours, assuming all the above specifications would
match a 12-volt "version" of your battery. I could help you more if
you want me to.

Hello again sageworksinc-ga

I have just a quick note to add because Peter Hayles the owner of the
http://www.angelfire.com/electronic/hayles/charge1.html web page
mailed me back saying that 18V is the max you can charge with the
charger he describes.

Maybe if you specify better which kind of battery you want to charge I
or some other researcher could more effectively help you.
Sorry

Sageworks --

There are off-the-shelf 24V chargers.  Most Mooneys (a brand of
single-engine aircraft) use a 24V system, so you can find inexpensive
chargers at places like Chief Aircraft:

Google search strategy:
Mooney + "battery charger" + 24V
