Fellow builders,

 

I have two Odyssey PC680s in the nose of my plane wired in parallel.  While
this setup works for the most part, starting the big 6 cylinder Franklin can
be a bit tasking.

 

I am considering doing something about it when we take the plane apart for
condition inspection and upgrade next winter.  So.

 

.         Would it make sense to move the batteries to the rear bulkhead
close to CG assuming the W&B issue can be worked out in the nose?  This will
reduce the wire run length.

.         Would it make sense to keep the batteries where they are now in
the nose and add additional 0-gauge wires (and back) to reduce current loss?

 

I know that going to 24V system will give me less current to drive the
starter but that is a fairly extensive change on the rest of the aircraft
systems.

 

Any other ideas?

 

Hiroo
