The Argofet 100-2 is a battery isolator that lets one alternator charge two batteries without joining them together. It handles up to 100 A from the alternator and works on 12 V or 24 V systems. Voltage drop across it is under 0,02 V at low current and averages 0,1 V at higher currents. It also has an alternator energize input and M8 bolts for the alternator terminal.
Our take
A voltage drop under 0,02 V at low current, averaging 0,1 V at higher currents, means each battery gets nearly the full alternator voltage while staying separate from the other. It is a two-battery unit rated 100 A.
From our buying guide
NMMA says not to mix battery chemistries or types in the same bank, and the makers add their own limits.
Check before you buy:
- Each maker sets its own alternator rules. Battle Born calls a DC-to-DC charger a simple and safe way to use alternator charging.
- Battle Born warns that a BMS shutdown leaves the vessel without power, and that one during alternator charging can severely damage the alternator.
- Ignition protection on a charger or switch is the maker's statement, so read what it says and which standard it names.
