The Victron Energy Argodiode 80-2AC 80A battery isolator lets two 12V or 24V batteries charge simultaneously from one alternator without electrically connecting the battery banks. Its high-efficiency Schottky diodes help protect the starter battery from accessory-battery discharge while keeping voltage drop low.
Rated for 80A maximum charge and alternator current, it includes a compensation diode and current-limited alternator energize input for compatible systems. Installed between the alternator and batteries, it provides dependable dual-bank isolation and efficient charging for automotive, RV and marine battery systems.
