Victron Argodiode Battery Isolator 80-2SC — 2 Batteries — 80A
Charge two or more batteries from a single alternator without linking the batteries together. The Argodiode isolator ensures the starter battery stays protected from accessory loads while the auxiliary battery is charged, reducing the risk of total electrical failure and keeping your engine ready to start.
Key features that maximize efficiency and reliability include:
- Simultaneous charging of two batteries from one alternator without a direct battery-to-battery connection.
- Low voltage drop thanks to high-efficiency Schottky diodes — approximately 0.3 V at low current and about 0.45 V at the rated output.
- All models include a compensation diode to slightly raise the alternator output, offsetting the diode drop and improving charging performance.
- Simple installation: place the isolator in the cabling between the alternator and the batteries; note that this can slightly reduce the charge voltage, potentially preventing a full 100% charge in some setups.
- AC diode isolators feature a current-limited energize input that powers the B+ when the engine run/stop switch is closed, addressing alternator behavior that requires a B+ on startup.
With the Victron Argodiode 80-2SC, you get a robust, efficient solution for keeping multiple battery banks charged and ready, while protecting critical starting power. For compatibility and support, consult your dealer to ensure the best setup for your vessel or vehicle.
