Like Argodiode battery isolators, Argofet isolators allow simultaneous charging of two or more batteries from one alternator (or a single output battery charger), without connecting the batteries together. In contrast with Argodiode battery isolators, Argofet isolators have almost no voltage loss. Voltage drop is less than 0,02 Volt at low current and averages 0,1 Volt at higher currents.
