Victron Argofet Battery Isolator 100-3 3 Batteries - 100AMP [ARG100301020R] Marine Navigation & Instruments | AIS Systems The low profile design includesArgofet Battery Isolator 100 3 3 Batteries 100AMP Similarly to 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 virtually no voltage loss. Voltage drop is less than 0,02 Volt at low current and averages 0,1 Volt at higher currents.
