The Victron Argodiode 80-2SC is a diode-based battery isolator that charges two separate battery banks at once from a single alternator or charger, without letting current pass between them. It suits marine, vehicle and off-grid setups where the battery banks need to stay isolated from each other.

Key features

• Isolates two independent battery banks while charging both from one source at the same time
• 80A continuous current rating
• Schottky diode construction gives a lower forward voltage drop than standard silicon diodes, reducing charging losses
• Compact and lightweight at 0.5 kg with bolt-on fitting
• Stops one battery bank feeding back into another, so starter and auxiliary batteries stay protected independently
• No moving parts or relay contacts

Product overview

The Argodiode 80-2SC uses Schottky diodes rather than conventional silicon diodes. Schottky diodes drop less voltage across them during charging, so the connected battery banks receive a more complete charge. That matters most in 12V systems, where small voltage losses affect the final state of charge.
