I am adding a 4th battery to my house bank.
I am trying to post this on my phone while sitting on my cabin sole.
Thanks.

Method 4

And here it is.
This looks odd but it's actually quite simple. What has been done here is to start with 2 pairs of batteries. Each wired in the proper "cross diagonal" method. Then each pair is wired together, again in the cross diagonal method.Notice that for each individual battery, the current always goes through a total of one long link and one short link before reaching the loads.This method also achieves perfect balance between all 4 batteries and may be easier to wire up in some installations. Many thanks to "smileypete" from Canal World Discussion Forums for this idea.

Hi, lifted straight from a previous link, agood way to go I believe.
Jeff if you are looking at new batteries I am in the same boat(so to speak) and we could do a deal for a larger quantity. Call me and let me know if you are interested.

I just wonder what method 4 gains you in battery life...

It also creates 3 gang connections & a lot more connections to corrode and fail.

Overkill science project IMHO...

@HooHaa - The notion about adding a new battery to an existing bank could be valid. Any chance your start battery is the same type and vintage as the original 3? Might consider incorporating the start batt into the old bank and using the new one for start?.

Ok. I have just completed a rewire based on the sketch in post 8. My batteries are in 3 different locations so it was really the only way to go.
Had to buy another 4 m of earth cable and some jimnastics and bloody nuckles later. It's all done. Just goto replace one of the batteries with a new one and it's all done. Will phone you shortly Bob.
Thanks again. I will be adding 240wats of solar next but that's on another post.
Regards Jeff.

Post #8 - method #2 won't sink the boat or make the batteries catch fire and is one of the 4 demonstrated methods - LOL...

Good luck with the solar!
