Geof;

I don't know the answer to your charger question, but I may have another
solution.

I have a 2 story barn and I keep my tractor in the lower level.
I installed an outlet on the lower level and wired it to an outlet in the
upper level.
I plug an extension cord from my tractor accessory outlet to the outlet on
the lower level.
This gives me 36V upstairs in my shop for testing, etc.
I used all of the round type locking outlets similar to the ones on my
tractor. I also painted them red.
That way there is no confusion on what they are for.
This may not conform to local Electrical Codes, but I live in a rural area
where no codes exist. 

Maybe this is a concept that you could use, if the charger method does not
work.

        Hi
        Now that we have developed a practical method for testing out 36VDC
motor (thank-you all), And given I am not really a big fan of batteries in
loose in the work shop.
        I got to wondering    OHMs' law say Vtotal =V1+V2+V3. As such 3-12V
batteries in series will supply 36V.  What would happen if you hooked 3
identical 12V battery charges in series?  Would you get 36V or an explosion
(Ha Ha)?. 12V chargers are very inexpensive and this might be a good source
of DC power for the bench.

        Thoughts
