David, I agree with your wiring diagram as set forth in the first part of your email, but I question if I understand your last comment about orienting the batteries + - then -+ then + - then - +. You end up with two + terminals and I don't know what voltage. The batteries have to be aligned as in the first part of your email + - then+ - then+ - then+ -, and you will end up with one bank of 24 volts, with a + and - terminal to connect to the next bank ++ and -- to power the boat. 2 banks of 24 volts, and most 6 volt batteries are 220 ah, so one 24 bank should also be 24 volt 220 ah, with the two combined at 440 ah.

I just wanted to clarify the manner in which the batteries are connected. I have seen owners try to connect all of the negative terminals together, or the supply positive and negative to terminals used to wire the batteries in series with varying results, ie melted cables, sparks, or simply a connection to a 6 volt supply. Love this site.

You will have one positive terminal( which I will call A terminal), and one negative terminal(which I will call B terminal) which are not connected to anything, and these are your new 12 volt positive and negative terminals. Make up four sets like this. Connect the 4 positive A terminals to each other, and the 4 negative B terminals to each other just like you do your 12 volt batteries, and then run this to your battery switch. Use the largest battery cable you can find for all connections, this is very important. These batteries have a lot of power, and undersized cable will not let you utilize all that is available.

I have 12 house batteries. . I assume that you would divide these into 4 parallel wired sets of 3 batteries with an output of 6 volts per set. . Then I assume that you would wire 2 of these sets of 3 in series producing 12 volts and do the same with the other 2 sets of three. . Lastly I assume that you wire the 2 12 volt pairs in series to produce 24 volts. I guess another option would be 3 sets of 4 wired in a series and then connect the 3 series-wired sets parallel to produce 24 volts? I assume that either method will require almost all new wiring? Any input will be appreciated. Regards, Bill Rouse S/V Security SM2 #387 Yahoo! Groups Links SPONSORED LINKS Sailing Sailing yacht Amel Boating sailing --------------------------------- YAHOO!
