Connecting two 150s to battery posts

[elvatoli60]

I'm connecting two classic 150 charge controllers to my 24v battery bank consisting on 8 Trojan L16 H.
I'm attaching the cable terminals to the positive and negative battery post on opposite sides of my battery bank, to have a more balanced flow of current, but I'm wondering that the terminals on top of each other are not the right way to do it, because the contact is not exactly the same.
On top of this, I have to connect my terminals for a battery monitor, ground rod and shunt.
Is not better to have two bus bars, one positive and one negative with , maybe 4 positions each ?
Where can I get something like this ?, or you have to build it from solid stainless steel ?

Hi elvatoli60,  Welcome to the Forum.

You are asking good questions.  Here is I Link to the MidNite Shunt,  and Shunt Busbar:
http://www.solar-electric.com/catalogsearch/result/?q=midnite+shunt

This is from a very good reseller,  assuming that you are in North America.

Here is some info from the MidNite Solar page on the Shunt and accessories,  Shunt:

Shunt Busbar:

Note,  the prices shown on the MN Site,  are essentially Retail,  many resellers discount these prices,  as is shown in the first LinK.

If you are using the WhizBand Jr,  the Shunt busbar should help,  AND  it is Tin-plated Copper.  Copper and Aluminum are considerably better electrical conductors that is Stainless Steel,  FWIW.
