Victron Energy Argo FET Battery Isolator
Shipping Costs:
We are unable to ship to some destinations due to weight/volume or Shipping Restrictions.
Charge multiple batteries or battery banks from a single alternator or charging source without connecting the batteries or battery banks together, avoiding a complete battery discharge if batteries are connected for charging and not separated when charging has finished.
Unlike standard diode battery isolators. Victron Energy FET Battery Isolators use FET transistors and have virtually no voltage loss. Voltage drop is less than 0.02 V at low current and averages 0.1 V at higher currents rather than a typical 1 V with standard diode battery isolators. With almost no voltage drop, batteries are charged at the full voltage of the alternator allowing quicker and complete charging.
FET Battery Isolators also feature a B+ power output to avoid alternator start problems. Some alternators require DC voltage to start charging. When the alternator is connected directly to the batteries this is not a problem, but when adding a battery isolator the alternator loses this DC power source. Argofet isolators have a special current limited energize input that will power the B+ when the engine run/stop switch is closed.
Available with 2 or 3 battery outputs and 100 A or 200 A alternator capacities.
