Why all this ranting over a proven fact that drawing 12V off of one
battery
of a 24V bank is not a good idea? A 40 amp 24/12 DC/DC converter capable
of running all the electronics on the boat can be bought for the price of
a
couple of golf cart batteries.

This is nonsense!

I agree with you completely, Glenn. It's just that I cannot stand those
people who claim to be in the know, are misinforming people who aren't.

You don't know squat about batteries in a circuit, Mr. Sprang. You are
the one doing the misinforming.

Read my other posts and do something about your ignorance.
Read this one, too. Perhaps if you read the truth three or
four times it just might sink in.

Nigel doesn't need anything but a couple of wires tapped off one
of the batteries in his series circuit and as long as a circuit is maintained
the two batteries will take and maintain an equal charge, irregardless
of the tap. It's only when the two batteries are isolated from the circuit
by a switch of some sort that the tapped battery will discharge and
the untapped battery will not be affected. Unless there is a circuit
there is no such thing as batteries connected in series. Connected in
a series implies or necessitates a circuit.

You can line up 20 flashlight D cells end to end and say they are connected
in series but until you complete a circuit they remain separate and distinct
cells. If you tap off the one in the center it will discharge and all the
others will not be affected but as soon as you connect them to a circuit
the discharged battery (ni-cad in this case) will become charged up at
the expense of the others until its voltage is raised and the others 'voltage
is lowered proportionally.

I hope this simple example will reduce your fogged thinking.
