When it was time to put 12V power in our car we started looking at where we
might hide a power source. Our hopes for hiding a full size battery in a
roadster would be no easy task. Most batteries end up mounted in the trunk
area which your upholsterer then covers. This seemed like a good place for
our car also, until we did some research on the newer AGM (Advanced Glass Mat)
batteries now showing up on the market. These batteries were first designed for use in
military combat aircraft where space and weight were at a premium and performance at any
position was a must. This technology has recently found a home in many motor sports
applications where high vibration, small space, deep cycles, fast charging rates, spill proof
cases, longer life spans, or versatile mounting choices are desired. This size and weight
savings allowed us to also try something different. Our plan was to weld in a boxing plate
between the deck former and the deck lid that tied to our roll bar for added lateral strength.
We could then suspended the battery & hold down from this steel plate making good use of
the unused space above our fuel cell.

There were a few small details that we wanted to incorporate in the design
of our 12V system. We liked the idea of being able to kill our whole system
for safety and security reasons. To do this we used a Painless Performance
remote master disconnect kit. This kit will allowed us to deactivate all battery
power with one small hidden switch. The remote switch controls the larger 250 amp master
disconnect switch capable of carrying the car's whole continuous 12V system load. This also
gives us a hidden theft deterrent feature and should keep any parasitic loss to a minimum
when storing the car for longer periods of time. The kit comes with a mounting bracket that
we modified to fit on one of our internal body supports. The body support will also work well
as an anchor point for our battery cables.

The last detail to be added was a set of remote charging terminals from Moroso
Performance. These terminals provide the convenience of being able to charge the battery
from a remote location. Before any holes were drilled we had to locate a spot with easy
exterior access for attaching cables, while making sure we had a clean cable run on the
inside. We chose a small valley in the trunk area to drill our holes. From the inside the valley
allows us to conceal the large battery cables while leaving plenty of room for an interior floor
panel to lay smoothly. From the outside, our two terminals land just forward of the rear roll
pan giving us easy external access.
