Victron Argo FET Battery Isolator - 100AMP - 2 Batteries [ARG100201020] Marine Hardware | Shaft Seals 1/2" NPT x 3/4" BronzeArgo FET Battery Isolator 100AMP 2 Batteries Similarly to diode battery isolators, FET 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 diode battery isolators, FET 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.
