The Victron Energy Argodiode 80-2SC 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 prevent accessory-battery discharge from also draining the starter battery while keeping voltage drop low.
Rated for 80A maximum charge and alternator current, it includes a voltage-compensation diode for improved charging performance. Installed between the alternator and batteries, it provides reliable dual-bank isolation for vehicle, marine and other 12V/24V multi-battery systems.
