Battery power

The beginings of my wiring diagram.  I have decided to have the Main starter battery (BAT 1)on the port side and the the House batteries (BAT 2), 2-6 volt golf cart, deep cycle, on the starboard side.  This was decided based on available space and weight distribution.  The diesel tank will go on the port side as well.  The diesel tank full will weigh about 70 lbs and the starter battery weighs in at 60 lbs.  The two deep cycle 6 volts on the  Starboard side weigh 63 lbs a piece.  The 6 volt batteries are a lot taller than the 12v starter batter and I can just about get them in the lazarette down low under the cockpit sole.

 










 By moving the control panels away from the batteries I have created some interesting issues with cable runs.  The biggest issue is with the batter selector switch which is tied to the main panel versus being separate.  The primary battery cables are still AWG 4 calculated at a 3% loss and the runs are only about 10' in length. All of the interior lighting and exterior lighting work out well with this location but the instruments that need to access the cockpit have a longer run.  To get the battery cases in I also have removed the engine exhaust pipe that was questionable if it needed replacement, until i tried to remove it.  It definitely was just a while away from rusting out connections.  The only bilge pump and hose was also removed to be replaced with all new.

I fashioned some risers out of treated 2x material that are glassed to the hull and will be painted with epoxy.  The shelf/platform is made of marine grade ply that will also be epoxied.  The batteries will go in individual battery boxes and the strapped down to the platforms.  The original assembly was floating in the locker and not very secure.
