xVictron Argodiode 80-2SC Battery Isolator 2 Batteries 80A
The Victron Argodiode 80-2SC is a diode-based battery isolator designed to charge two separate battery banks simultaneously from a single alternator or charger, without allowing current to flow between them. It is suited to marine, vehicle and off-grid applications where battery bank separation is essential.
Key Features
- Isolates two independent battery banks while allowing simultaneous charging from one source.
- 80A continuous current rating, suitable for a wide range of alternator and charger outputs.
- Schottky diode construction reduces the forward voltage drop compared to standard silicon diodes, minimising charging losses.
- Compact and lightweight at 0.5 kg, with a straightforward bolt-on installation.
- Prevents discharge from one battery bank feeding back into another, protecting starter and auxiliary batteries independently.
- No moving parts or relay contacts, giving a maintenance-free service life.
Product Overview
The Argodiode 80-2SC uses Schottky diodes rather than conventional silicon diodes. Schottky diodes have a lower forward voltage drop, typically around 0.3V to 0.5V versus 0.6V to 0.7V for standard types. In practice this means less voltage is lost across the isolator during charging, so battery banks receive a more complete charge. This matters particularly in 12V systems where every tenth of a volt affects the final state of charge.
The "2SC" designation indicates two output circuits from a single common input. One input connects to the alternator or charger; the two outputs connect to separate battery banks. Current flows freely from input to each output, but the diode arrangement blocks any reverse flow between the banks. A starter battery and a domestic or auxiliary battery can therefore be charged together without the risk of the auxiliary bank draining the starter battery when the engine is off.
At 80A, this isolator covers the majority of single-alternator installations in leisure vehicles, motorhomes, boats and light commercial vehicles. For higher current applications or three-battery configurations, Victron offers other models in the Argodiode range.

Installation Notes
The Argodiode 80-2SC should be installed by a competent 12V or 24V auto-electrical engineer or marine electrician. Ensure the input and output cables are correctly rated for 80A continuous use and that appropriate fusing is fitted on the input feed. The unit should be mounted in a ventilated location as diodes generate heat under load. If the system includes a voltage-sensitive relay or a battery-to-battery charger, verify compatibility before installation to avoid conflicting charge management.
