Actually, I believe the BIM will isolate the battery banks once they are charged. In other words, it will isolate (open the combiner in the BIM) which-ever bank is fully charged such as chassis (start) battery bank while you are plugged into shore power at the campsite, or isolate the house batteries while you are driving down the road (should they not be required). This solves the issue of overcharging especially the chassis (starter) batteries while plugged in at the camp site or when you are equalizing the house batteries (which is deadly to the starter batteries).
