Re: Electrical Engineering Problem

There is more to consider than voltage drop and weight distribution. That size bank must be given proper ventilation, intake and output. Fuse protection at the batteries is critical and putting a battery charger and/or inverter above or even inside the same small compartment if not properly ventilated can be dangerous. You don't need an electrical engineer but a consult with an ABYC Certified Marine electrician would be very wise.

You can find one here .... Certified Technician Directory - American Boat and Yacht Council

That hysterical laughter you hear as you sail a way in your "new" boat ..... is the seller.

Re: Electrical Engineering Problem

don't do it. most inverter / chargers want to be within 5' of the battery bank. and that is when 4/0 cable is used. you'll have loss from all your big alternators unless you run huge wires. it will definatly cost you 1000's. a 25' run of pos / neg 4/0 is already $1000 just the wire. and that's not even big enough

Re: Electrical Engineering Problem

As others have said -- I wouldn't do it. You even doubt yourself that it will do much for your trim issue. I would attack that problem head on, and don't get your batteries mixed up in it -- at least for now.

All my boats have always floated exactly on their lines and I would never be satisfied with a severe trim problem as you describe. I would figure out what the cause is. The list, in particular, is very disturbing.
