Victron Energy Argo Diode Battery Isolator 160 amps 2 Batteries Blue. 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 03 V and at the rated output approximately 045 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.
