Victron Battery separators

Similar to diode battery isolators, Argofet battery isolators make it possible to simultaneously charge two or more batteries from an alternator (or battery charger with one output), without connecting the batteries together. Unlike diode battery isolators, Argofet battery isolators have virtually no voltage losses. Voltage losses are below 0.02 Volt at low voltage and an average of 0.1 Volt at higher voltage.
