I had a set of Exide.  No idea what model,  they did the job.  My next set
will very likely be bought from RAE Battery,  a local wholesaler and mail
order supplier.

A few possibilities,  in no particular order:

Re-wind the motor for 36V.
   The armature has a low number of turns,  so rewinding is just tedious,
as    opposed to nightmare.  The field coil is easy,  as there is only 1,
bobbin    style.

build a DC-DC converter from 36V to 18V,  with a tap at 12V for the lights.
   Fairly advanced electronics project,  has to deal with full (stall) load
   current without burning out,  or be more complicated with overload
protection.

For the mechanically inclined,  find a way to get 2 winch motors mounted to
the drive gear,  and wire them in series.

Find a 36V surplus motor powerful enough,  and use a shaft coupler and make
an adapter plate.
   Either one should keep a machinist busy for a little while anyways...

At this time,  I am not sure which is easiest.  I just threw them out to
stir up ideas.
