Connecting battery cables

Hi all, we’re finalising our 12 volt battery set up and running the pos & neg battery cables to the battery bank of 4 Trojan t105’s. 
 

We’re running the cable through both an internal and external isolator as well as having a mega fuse. 
 

Where should we connect the cables to on the battery bank itself? We’re not sure which battery of the 4 the pos & neg should connect to? 
 

thanks, 

Adam

Thanks for all the replies! Yes they are 6v wired up to give 12v around 400ah. So would the drawing above suit? 

Rearrange @robtheplod's drawing to put battery 2 below battery 1 and battery 4 below battery 3 and you can see it's effectively the same arrangement as I posted from the Smartgauge site. So yes it's the way to go. And rob's version probably makes more sense in physical layout terms.

With the external connections taken from the diagonally opposite corners, to balance the load between the two pairs.

 

Not that it matters a hoot in real life.

 

It's more technically correct but the end user would never tell the difference.
