Wiring Parallel and Series of 24 Volt System

[IMG]http://i1061.photobucket.com/albums/...ps871ywftc.jpg[/IMG]

Just drew this diagram. The image on the right is correct according to what I have just read. But the wiring to my trolling motor would be easier for me with the image on the left with my boat layout if it's possible. So my question is......if I have all these batteries linked like this, Can I just hook my trolling motor up to the positive and negative post of the same battery and still keep my voltage approx 24 and approx double my amp hours?

Scratch that. Dont think im going to connect them all because I dont want them in my boat ALL the time. Just when cranking or on windy daYS. Going to get some quicik disconnect plugs and just unplug one joined set of batteries and plug the other one in.

Looks to me like both diagrams would result in 12V ...not 24.

Thats parallel wireing four batterys wired like you show is 12 volts Just wire two batterys in series pos to neg and you will have 24 volts......connect TM to the pos and negative posts that are not connected

This is what it looks like

If you want to use 4 batteries to get 24V, you could do this. The extra 2 batteries would double your amp hours.

Do I need a wire to go where the green line is in the image above? Or just that original drawing all I need? Thanks for all u guys help. I really appreciate it!

You dont need the green wire

Awesome! Thankyou!

Correct, no green wire. The green wire would short it out. Be careful not to do that.

So.... based off the image above that has been corrected, I already have 2 batteries added up to equal 24volts. So if I wanted more amp hours I can just connect a new battery to one of the already existing batteries on one side n my boat that is wired in by connecting the positive post to a positive post and a negative post to a negative post? And then do the same with a 2nd battery on the other battery that is already wired in?

Yes, that is correct. That is the way batteries are connected in RV's. They connect multiple 6v batteries together in a combination of series and parallel connections to get a battery bank that puts out 12v. There's multiple ways to do it. Here's a picture of another way that would work. In the picture below, they are using 6v batteries to end up with 12v. If you do the same with 12v batteries, you'll get 24v.
