Rob,

Try mounting the battery in a tight battery box and mount the box on the
motor mounts.  I did on the short mounts and the clearance is tight but
workable.  the clearance is about 3/8ths inch from the cowling. The battery
is not horizontal but is parallel to the top bar.  This works fine with gel
cell batteries.  The longer mounts should be easier and you save the space
on the firewall side for other gingerbread and air exhaust.  I would advise
you blast air into the box to increase life expectancy of the battery. I
made a custom clamp to handle the major load and two adel clamps all three
clamped to the motor mounts very close to the mount bases and motor mount
area.  This avoid a bending load on the mid span of the motor mount bar.  Be
sure the clamps have rubber between the clamp and the motor mount.

Another thing we should look for is to avoid using tie wraps to secure wires
on our motor mounts.  Nylon tie wraps with vibration can work through metal.
Not a good idea.
