Not at all!
If there is a fault in the links between the batteries with the positive
taken from one end and the negative from the opposite end of the bank it
will show up as voltage drop on the output when you put the system
under load.
If you take both positive and negative from the same end it will never
show as the batteries will be effectively disconnected from the system
by the bad link.
I am talking about batteries in parallel here in a series/parallel
combination it wont be so obvious.
As for the copper bars, the ones I use are about 1" x 1/8" standard UK
power distribution buss bar, I use adapters that convert the battery
posts to 8mm (5/16") bolts and this usually brings the bars above the
top of the battery handles etc. I just cut and drill the bars to fit
the installation and when finished connecting them lightly cover the
terminals with Vaseline.
