VICTRON ARGOFET 200-3 BATTERY ISOLATOR
Similar to diode battery separators, FET separators allow two or more batteries to be charged simultaneously from one alternator (or single output battery charger) without connecting the batteries together.
Unlike diode battery separators, there is virtually no voltage loss in FET separators. The voltage drop is less than 0.02 volts at low currents and an average of 0.1 volts at higher ones.
