ARGO FET BATTERY ISOLATORS: NO VOLTAGE LOSS

Similarly to Argodiode battery isolators, Argo fet isolators allow simultaneous charging of two or more batteries from one alternator (or a single output battery charger), without connecting the batteries together. In contrast with Argodiode battery isolators, Argofet isolators have virtually no voltage loss. Voltage drop is less than 0,02 Volt at low current and averages 0,1 Volt at higher currents.

When using ARGO FET battery isolators, there is no need to also increase the output voltage of the alternator. Care should be taken however to keep cable lengths short and of sufficient cross section.
Alternator energize input
The new ARGO FET isolators have a special current limited energize input that will power the B+ when the engine run/stop switch is closed
