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.  Specifications: Maximum Charge Current (A): 200 Maximum Alternator Current (A): 200 Number of Batteries: 2 Nominal Battery Voltage: 12V and 24V Connection: M8 bolts Weight kg (lbs): 1,4 (3.1) Dimensions (H x W x D): 65 x 120 x 200 mm (2.6 x 4.7 x 7.9 inches) Please contact your dealer for any returns, repairs or support issues related to this product.

Battery Isolators

Argo Diode Battery Isolator - 160AMP - 2 Batteries Diode battery isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries together. Discharging the accessory battery for example will not result in also discharging the starter battery. The Argo Battery Isolators feature a low voltage drop thanks to the use of Schottky diodes: at low current the voltage drop is approximately 0,3 V and at the rated output approximately 0,45 V. All models are fitted with a compensation diode that can be used to slightly increase the output voltage of the alternator. This compensates for the voltage drop over the diodes in the isolator.
