My personal Amigo brand Amigo mobility scooter, which
apparently is the sort of thing you're talking
about, uses two 12V batteries in series to get 24V,
and has a lever control for the power output.
Pretty much their entire line uses these systems,
and many other companies do as well.
My suggestion is... call the local vendor/repai shop
handling these scooters. Chances are they've
got exactly what you need either in their junk
box for a nominal $5, or brand new for $50ish.
(the brand new ones will vary a HUGE amount depending
on how much they think they can get from you).
------------------------
I have to agree, talk to a pro who has insurance. Although I've
repaired mobility equipment and built electric vehicle prototypes I
feel that the liability concern is too great for home shop
re-engineering.

The fellow isn't physically disabled, by the way.
Whether he has other "challenges" I will sidestep.
Apparently he has been directed to a "regulator" which does the
needed.
Sorry I am short on background - I didn't even want to go there about questions like "why?".

You or he might get better results by searching for information on do-it-yourself electric bicycle controls.
As a technician I was put in the difficult position of being asked to
design and wire electric motorcycle controls after the electrical
engineers decided to back away from that project. I've done enough in
that and the medical electronics field that I've learned to be very
careful about what I write. I was almost sued for using a circuit I
found in my car's shop manual, that another company claimed was their proprietary secret.

P.P.S. I've got a buggy crane I think might someday make a good vise
crane in the shop courtesy of the same friend. Just need to find the
right DC power supply for it without having to maintain a battery on its cart.
---------------------------
A Bruno hoist? I have one that was removed from an old SUV but I found a pickup truck bed crane mounted on a taller pipe swivel stand to be more adaptable.
When I need a temporary means of lifting and moving something heavy I
set up the outdoor extension of one of my overhead gantry tracks. It's
made of two pieces of 3" by 8' steel channel, surplus pallet rack shelf supports I bought for $10 each. Its easier to install than a length of I (wide flange) beam because each piece weighs only 33 Lbs and the straps bolted between the ends are good hangers. Changing their position
requires simply drilling new holes through the webs.
I do have a standard cherry picker / engine hoist. Its not really
convenient for placing a vise on a mill table or a chuck on a lathe
spindle. I do plan to make a heavy tool cart for the new (new earlier
this year anyway) South Bend Mill in the back. I expected it will be
plenty heavy enough when loaded up with tools to allow a small crane arm
to swing a 100lb vise out over a table, and when not in use the arm can
swing back over the cart to not be in the way.

I had already set it up. I want to move one of my 8 inch vises from
the Hurco to the South Bend, but haven't done it because I am not
looking forward to lifting it with my arms extended over the machine.
(I have in the past. These vises were originaly on the Charter Oak
piece of trash bed mill.
For other not excessively heavy things a chain off the bucket of the
front loader works too. Its rated for 750 lbs, works fine to about
1200, and has lifted upto 2000 but maxes out with just a few inches of
lift at that weight. I also rebuilt one of the hydraulics recently...
My shop is pretty crowded though. Bringing the loader inside to do
any real work optimistically takes a half day of moving things to
clear a wide enough path.
I've seen some little cranes mounted to lathes similar to the HF pickup
truck bed version. Able to lift item off the cart and on to the
machine...
