Similar to the Argodiode battery separator, the Argofet battery separator allows two or more batteries to be charged simultaneously from an alternator (or a single output battery charger) without connecting the batteries together. Unlike the Argodiode battery separator, the Argofet battery separator has virtually no voltage drop. The voltage drop is less than 0.02 volts at low current and an average of 0.1 volts at higher currents.
