Proper Balance of wiring 3 12V batteries
I have read a lot here on the importance on wiring additional batteries properly (thx pianotuna). I'm looking to wire 3 12V T1275 in parallel, and looking for how other's have physically connected 3 ...

Hi 2oldman,
Yes, there are two other ways.
Best is a buss bar with equal length cables.
Alternate is all equal length cables but double up on some of them.
i.e.
feed/charge positive==positive--positive
and
negative--negative==negative feed/charge
the equal signs are the doubled up interconnects of equal size and length.
My own opinion is that this does not work as well as the buss bars. This second method MIGHT work better if the doubled up cable was beefed up to be 1/2 the resistance of the single cable. For myself, I'll keep to the buss bars.
I don't have the math skills to figure out if this variation really makes a difference. The buss bars DO make a difference.

Take the + from battery one and the - from battery three. Is there another way?
