Well negative RBA contact is much different than I was thinking of battery contact
Regardless of the nut or hybrid used on a billet box, it will contaminate due to the box being aluminum.
Just how dissimilar metals react to one another when current is applied and or ran through it(bimetallic corrosion)
Why many modders like Mums, BMM etc use copper and or brass threads… less prone to this happening.
But yeah… stainless on aluminum probably the worst for conductivity, but we are talking micro-ohm differences…
I’ve never had a build read correctly in any of my RBAs, most are close though.
For instance..
2.5mm 7.5 wrap 28g N80 says 1.06 ohm calculated.
I can put that on any boro rba and it will read higher when dry burning on a DNA200 mod (1.19ohm)
But when I put it on the Stash 2.1 it reads 1.009
1.06 vs 1.009, is .054 of an ohm, and you can factor in gunk on a coil which changes ohms over time… and we are looking at 1.06 and 1.02…
Temp control takes live reads and fluctuations when computing its temp guessing… and the variance is nearly moot.
Battery life, I couldn’t even quantify a change of optimizing 75mAh more (guess)
I would have to test that while hooked up to escribe over the length of the battery curve.
Anyway, not trying to dissuade you from the path you’re considering, but I could see funds and effort only producing at best an insignificant improvement…
Being that the greatest affect on conductivity is the sum of the RBA, more than the BB.
