From Victron energy site....

"Argo FET Isolators are High Efficiency - Low Voltage Drop!

Victron Energy FET Battery IsolatorsSimilarly to silicon diode type 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. It allows discharging of batteries independently of each other without effecting the other. Popularly used on Rv's, Boats, Commercial vehicles where both starter and house batter banks exist.

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. "
