Expert Reply:
The primary difference between the Redarc Smart Start Battery Isolator # 331-SBI212 and # 331-SBI212D is that the Isolator # 331-SBI212D is actually a dual-sensing battery isolator, which means it can transfer power in either direction when connected in-line with 2 batteries. When connected in this way with 2 batteries, 1 that is charged by your alternator and another that is connected to an outside source, it will transfer power in either direction to keep both batteries charged.
The Start Battery Isolator # 331-SBI212 will only pull power from your start battery to charge the auxiliary battery.
I have attached the specific installation/operating instructions for both products that you can also check out.
