$75 bucks for a 2 troy oz bussbar. Im all over that like a duck on a junebug! NOT! I bet Martha Stewart uses those and cant understand why everyone else doesn't. Im actually wondering if ANYONE could actually see any difference in that vs copper?I'm over it. Going to use silver bars in the future.
I'll just say they are aluminum....
Yes, conductivity is 75% compared to electrical grade copper. IACS = International Annealed Copper Standard.Thank you! So does this say conductivity is a 75? Im trying to understand where it fits in with silver, copper, aluminum, gold , zinc etc.
Certainly was a good deal for me.Raw copper bar stock cheap... they also have the 4" wide on sale.... or regular price for any of it.

Cut them out or have them cut the right width or length and trim yourself.
So do you think you would see any difference if you went with c110 ? Im just trying to wrap my head around this to see if anyone could tell that they have more or less "power" depending on their choice of bussbar. Is this whole thing like "my production car Bugatti Veyron will do 267mph compared to your Bugatti Mistral will only do 261mph?are 6063-T5.

With bussbars this is only a matter of needed size and maximum temperature rise. You can compensate the worse material by selecting larger cross-section.So do you think you would see any difference if you went with c110 ?

......And if we go with the prettiest most electrically conductive copper bussbars and then thru a standard service panel which has ALUMINUM bussbars does it really make that much of a difference?
Exactly what I was thinking. Resistivity is measured in meters. Who has 39in long bussbars? Im sure someone does.100 feet of busbars.

I looked up SparkyJJO's aluminum bars and the resistance was something ridiculously small like .000000032 ohms per meter!
So also I've come to the conclusion that unless you're running hundreds and hundreds of amps thru your bussbars the difference in the top "cost-wise" materials are pretty negligible .
+60" of busbar on each leg and 120kwh of battery. To some extent, it probably affects how each bank charges/discharges, but most days it stays in float long enough that everybody gets what they want.Exactly what I was thinking.

Even so I doubt it would make very little difference even if you switched to aluminum and say doubled the thickness? Who knows unless you have a sophisticated lab or even the desire to experiment...+60" of busbar on each leg
Considered al but IIRC, it was going to be as expensive as cu. It wasn't the difference in ampacity that worried me as it would be MacDonalds supersized, it was all those cu lugs bolting up to an al bar creating lots of places for oxidation, or whatever that krap is that likes to grow in those spaces. Noalox works, but hey, why push the luck.Even so I doubt it would make very little difference even if you switched to aluminum and say doubled the thickness?

It actually is quite surprising the voltage difference between each pack attached to a central busbar as indicated on each BMS screen. I have all 8 lit up now. All cable lengths are the exact same length, that is explained in a video too.I looked up SparkyJJO's aluminum bars and the resistance was something ridiculously small like .000000032 ohms per meter!

All JK's. No I didn't calibrate the BMS but one can see the differences in current draw too. With cables coming from each side of the box to the central busbar, the cables had to be mounted on the positive busbar with different spacing between holes.Can you calibrate the voltage on the BMS? (you can if they are JK). Use a decent multimeter as reference.
