Why do battery needs a float current?
I mean, when it's full, floating and there are no loads? To fight the self-discharge, alright. But it draws a bit more than self-discharge would require. I have 300 AH AGM bank, self-discharge ...

From memory, the whole Rogue controller loss is ~5% of input power, this includes the display. I don't have fancy-shmancy Trimetric monitors ;)
5% controller loss is nothing compared to 7-fold "overhead" that Im seeing (2AH/0.3AH=7). Besides, I think the controller 5% loss is not recorded on the display. When the log on display says "2 AH out", then it means "out", i.e. from controller to battery. Unless I'm missing something.
