I'm still waiting for distroblotto to do it
I think I did it a long time ago, but I forgot. But as you would expect the conductivity is superb. Gotta keep it clean though.
The problem with voltage drop tests is that it's difficult to determine how much of the "drop" is actually battery sag. Thus, you can never compare one person's results with another person's.
BIL is doing some wiring work on his house and I'm waiting for him to return my Fluke. Did a quick test on Brassy, Copper, 6068 and SS using a Fat Daddy voltage tester and four brand new freshly charged HG2's to 4.2 volts. Without load, voltage drop across the board was about .6 with Copper coming in at .5. Under load with the same Narda built to 0.5 ohms on all, the voltage varied between 3.7 and 3.9 with Copper coming in the highest. Not really a scientific result but the seat of the pants test is telling me it's not really enough to worry about.
