I notice many people discussing the number & location of batteries they
can use in their donar cars. A trick that has served me well was to
purchase a plastic scale-model of my donor. I lucked out in that it was
available in 1/8 scale. I "semi-assembled" it, leaving body, etc.
free, for easy removal. I cut models to scale of proposed motor,
controller, batteries, etc. I cut out the body sections that will be
modified in the real thing, and then played around with different
configurations. At 1/8 scale a 12v flooded is about an inch long, so
it is quite practical to do this. If you can only find the more typical
1/25 scale kit of your donor it will be a bit more challenging...

It has been quite helpful to me, I suggest people in the idea/design
phase search the net for available models in their car of interest.

Sometime ago, I think it was in the 80's, I saw a article in the Advance
Vehicle News magazine about Golf and Western electric van. Golf and Western
makes large standby battery systems for float and backup power for computer
centers.

This type of battery are gold titanium type which are about 10 inches wide
and 8 inches high, but they are about 15 feet long, which gang the internal
cells all together. I think there were about 144 volts each for a 120 volt
system.

These slid in under the van in a rack panel type of chassis. You can slide
the whole 15 foot long battery out that had two dolly wheels that came down
to hold it, or you can slid it into a separate dolly rack, that you can roll
it around for maintenance.

I said this would be great, where they use two of these 15 foot long
batteries in there maintenance van that they said it went over 300 miles. I
gave them a call for some data and how much they would cost.

There cost to build each battery come to be about $250,000.00 each, so that
was not a great ideal, unless the gold went up over 4 times the value, then
you might come out ahead.
