Optimizing Battery Bank Efficiency

We have eight batteries hooked up in parallel, positive at one end and negative at the other running into their respective bus bars. Would connecting a second positive cable to the positive bus bar, half way up the battery chain, optimize the flow and use of power?

I don’t know for sure, so I’ll wait for an expert to answer but I would think not. I would think it might reduce your available amp hours.

What type batteries? Are you using a solar array to charge them or some other source. Exactly what kind of "bus bar" are you talking about? Any chance you could post a picture?

If you have the positive connector cable at the north end of the positive bus bar, put the negative connector cable at the south end of the negative bus bar. That's all you can do to even out the load.

Lots of good info on batteries on this site:

http://www.marxrv.com/12volt/12volt.htm

When the batteries are wired as picture the path across each battery is the same length and balanced equally. A short path on say the negative side is a longer path on the positive side. Overall each battery path is the same length. Chris

Here is the picture with hop counts added.

The path for all four the batteries has the same hop count of 3 hops.
