That smartgauge is what I was trying to say in the OP where I had three batts done as though two.
He says the middle battery discharges less than the end ones, but I didn't measure that. I saw the middle battery lagging on the recharge by its SG showing it not as full as the end ones.
I don't know why the middle battery doesn't come back on the recharge where it takes fewer amps, since it also provides fewer amps on the discharge. Maybe while camping there is more time for them to even out on the discharge side so the recharge is uneven right after, allowing no time (days?) for things to even out.
After reading the smartgauge article again (I thought I had read and understood it. LOL), I agree that what you observed is probably valid.
I'm not as surprised, as you, that you would see the same thing on the recharge as you would observe under load contribution measurements.
