Victron Energy Argofet 200-3 Three Batteries 200A Retail

The Victron Energy Argofet 200-3 200A battery isolator is a FET-based device that lets three 12V or 24V batteries charge simultaneously from one alternator or single-output battery charger without connecting the battery banks together. Rated for 200A maximum charge and alternator current, it helps prevent an accessory battery from discharging the starter battery.

Its low-loss FET technology keeps voltage drop below 0.02V at low current and around 0.1V at higher current. A current-limited alternator energize input supports alternators that require B+ voltage to start charging, providing efficient, reliable multi-battery charging for high-current 12V and 24V systems.
