Victron Argofet battery isolator max charging current 100a, connection for two batteries. The Argofet isolator allows, in the same way as diode isolators, the simultaneous charging of two from one generator without connecting the batteries together. In contrast to diode battery isolators, Argofet isolators have virtually no voltage loss. The voltage drop is less than 0,02 Volt at low current and on average 0,1 Volt at higher currents.
