Argofet 200-2 Battery Isolator - 200AMP - 2 Batteries

Similarly, to Argodiode battery isolators, Argofet isolators allow simultaneous charging of two or more batteries from one alternator (or a single output battery charger) without connecting the batteries. Discharging the accessory battery, for example, will not result in discharging the starter battery.  

In contrast with Diode battery isolators, FET isolators have virtually no voltage loss. The voltage drop is less than 0,02 Volt at low currents and averages 0,1 Volt at higher currents.

When using Argofet battery isolators, there is no need to also increase the output voltage of the alternator. However, care should be taken to keep cable lengths short and of sufficient cross-section.

Example: When a current of 100 A flows through a cable of 50 mm² cross section (AWG 0) and 10 m length (30 ft), the voltage drop over the cable will be 0,26 Volt. Similarly, a current of 50 A through a cable of 10 mm² cross section (AWG 7) and 5 m length (15 ft) will result in a voltage drop of 0,35 volts!

Alternator Energizes Input

Some alternators need DC voltage on the B+ output to start charging. DC will be present when the alternator is directly connected to a battery. Inserting an Argodiode or Argofet splitter will however prevent any return voltage/current from the batteries to the B+, and the alternator will not start.

The new Argofet Isolators have a special current-limited energize input that will power the B+ when the engine run/stop switch is closed.
