The ProCon IF offers the ability to link together as many battery banks as you wish and therefore charge different battery banks when the engine is running. The relay is necessary to prevent current flowing back the way it came. A conventional relay incurs 0.5A to operate and can suffer from voltage drop across the ignition feed cable. The Sterling ProCon IF is zero voltage drop and only requires 1mA of current to operate.
