SIC?s Low Drop automatic battery isolator electrically separates each battery so that the one with the most charge (typically the starter battery) does not ?float? together with the discharged batteries. When charging, the isolator ensures that the battery with the greatest need is selected. SIC Low Drop battery isolator has a voltage drop of less than 0.25V. During charging phases 1 and 2 there is 0.7 Volt in voltage loss, during phase 3 there is 0.25 Volt.
