Rod, I've found McMaster and their 3350K212 Super-Conductive 101 Copper Rectangular Bar, 1/4" x 1" for my project. I could not find specs. Do you know if this is adequate for a max of 500amps? Also, I read through your BVM article previously when I first installed the BVM a couple years ago and also recently refreshed my memory reading again through some of your other articles. All good stuff and thank you. However, now that I've done some reading and have become dangerous with some knowledge, you've got me wondering if I should also look at rewiring my house bank to more effectively balance the use and charging of my batteries (I've just invested in new AGM's).
So now that I'm wondering, my question is, instead of having the positive terminals on each of the house batteries coming back individually to a common stud with fuses and having each of the negative terminals coming back individually to a common block on the battery side of the BVM shunt, should I rewire them so that the positive terminal from one battery connects to the positive on the second battery and then connects to the house load/charging circuit while the negative from the second battery is wired to the negative of the first battery going in the opposite direction back to the battery side of the BVM shunt?? (note: my house batteries are in different locations so the cable lengths will not change regardless of which connection configuration is used)
I've attached a diagram for my current state of wiring and the possible change I described above. Thoughts?
