Victron smart shunt
I just installed a Victron smart shunt in our class c. I have two group 27 batteries so in setting up the device I entered 200 in battery capacity, 50% in discharge floor and enabled Soc alarm at 50%...

Nope.
Group 27 sized RV/Marine "deep cell" batteries typically have a Ahr capacity of closer to 80 Ahr each perhaps a bit less. With 2 you have 160 Ahr max and at 50% about 80Ahr for the pair.
Since these are in reality a "combo" start/deep cell, they do neither job well and also have a much shallower DOD if you really want the get the maximum rated discharge cycles.. Basically not much more than 20% of the capacity should be used if you care about getting the max life from them..
