FET isolators allow simultaneous charging of two or more batteries from one alternator (or a single output battery charger), without connecting the batteries together. Unlike diode battery isolators, FET isolators have virtually no voltage loss.  When using ARGO FET Battery Isolators, there is no need to also increase the output voltage of the alternator. Care should taken however to keep cable lengths short and of sufficient cross section.

Victron Energy's Argofet isolators allow simultaneous charging of two or more batteries from one alternator or a single output battery charger without connecting the batteries together. Unlike Victron's Argodiode battery isolators, Argofet isolators have virtually no voltage loss. Voltage drop is less than 0.02 volts at low current and averages 0.1 volts at higher currents.

Argodiode 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. Low voltage drop due to the use of high efficiency Schottky diodes.

Argofet Battery Isolator, 2 Batteries 100 Amp

Diode battery isolators allow simultaneous charging of two or more batteries from one alternator, without
connecting the batteries together. The Argo Battery Isolators feature a low voltage drop thanks to the use of Schottky diodes. 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.
