Battle Born Charging
This might answer some recent questions. The table is not accurate wrt to the BB comments--don't go by it by the table itself. Wade through the questions and answers to get the true picture. Tak...

Furnace was just recently rewired srraight to the battery because furnace was acting up and so i quickly wired it straight to battery with thicker cables because very cold that day and needed heat asap.
Fridge is wired to the shunt
Thanks for clearing that up. So that would not show the furnace cycling except perhaps if you dug into the times vs voltages on the way up. Your AH count would be way off, but by using cell voltage to measure SOC, you still get to the BB protocol for when to stop the charge and when BB says it is "full".
Your converter might still be a 55 instead of a 60, but what if you also had a couple of lights on the whole time for 7 amps worth? That would be on the shunt and the lights don't cycle.
It looks like you can operate an Li monitoring it their way, but you won't be able to tell the battery capacity is falling with age until it "doesn't last as long". That is what the AH counting method of monitoring is supposed to do for you, so you don't have a dead battery at 3am.
It will still show the same voltages if it is like a lead- acid (except under load). A resting L-A battery shows 12.7v when it is full even when full is not as many AH as it used to be when new.
