Battery isolators enable you to charge two or more batteries from one alternator (or a single output battery charger) without connecting the batteries together. Discharging the accessory battery will not result in also discharging the starter battery.
When using Victron Argofet battery isolators, there is no need to increase the voltage output of the alternator, however care should be taken to keep cable lengths short and of sufficient cross section.Ã
Some alternators need DC voltage on the B+ output to start charging. Obviously, DC will be present when the alternator is directly connected to the battery. However, inserting a diode or FET splitter will prevent any return voltage/current from the batteries to the B+ and the alternator will not start. Argofet isolators have a special current limited energize input that will power the B+ when the engine run/stop switch is closed.
