Actually that is not what would happen. ACR's such as those from Blue Seas have various safeguards against combining batteries that have problems. An ACR will only close when the battery voltage of the bank being charged goes above about 13.0V. So if the charging bank is low, it would not close until that bank came up higher than the normal fully charged resting voltage of the second bank - no current would ever flow from the second bank to the first. Also, they will not close if the second bank is very very low.
