Victron Energy ArgoDiode battery isolators 160-2AC allow simultaneous charging of two batteries from one alternator. Alternator energize input Victron Energy new AC diode isolators feature a special current limited energize input that will power the B when the engine runstop switch is closed. 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. Victron Energy 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.
