More Solar for "Us"
Ok, I went off.the deep end? Bought 3 used 37watt uni-solar panels and a blue sky 2000e controller for the hefty price of $400, They were being listed as 75w panels, they are not The tested open...

Hey Jim,
Glad we're in agreement. But I certainly don't want to get dragged into a my solar controller is better than yours debate. ;-)
Not dropping the setpoint voltage is definitely a Blue Sky weakness. My old G24 batteries used about a quart of water a year. And that's with the setpoint at 14.0V! More than 99% of my charging is done solely with solar. BTW, welcome to the solar club. You will be happy with it.
I don't understand Wiz last measurements.
Controller 14.64V
Battery 13.81V
Current 10.1A
That would indicate a line resistance of 0.83V/10.1A = 82 mohm
Previously I calculated 11 mohm.
Something is not right.
