Victron Argo Diode Battery Combiners 40A & 80A

Victron Argo Diode Battery Combiners 40A & 80A are diode-based battery combiners designed to simplify dual-battery charging in boats, RVs, and off-grid systems. These units provide automatic charging and isolation without the need for external relays, making them a practical choice for space-conscious installations.

• Current ratings: Available in 40A and 80A variants to match your charging needs and secondary battery size.
• Diode OR‑ing: Diode-based battery combiners that automatically connect a secondary battery when charging is present and isolate banks when not.
• System compatibility: Optimized for 12V and 24V DC systems, suitable for marine, RV, and off-grid applications.
• Installation and durability: Compact, robust design that fits into standard installations and works alongside other Victron components.
• Technical Overview: The Victron Argo Diode Battery Combiners (40A and 80A) provide a simple, reliable way to manage two battery banks in one system. By using diode-based OR-ing, the primary charging source—such as an alternator, solar controller, or shore power—feeds both banks when present, while each bank remains isolated when charging is inactive, preventing cross-conduction and accidental discharge. The 40A model suits smaller auxiliary banks, while the 80A model handles higher charging currents common in larger boats and RVs. Designed for 12V and 24V systems, Argo units thread into standard battery interconnects and integrate easily with Victron controllers, battery monitors, and protection devices for a cohesive energy management solution. No external relays required.

This configuration delivers practical, technical reliability: you get automatic, safe two-bank charging, reduced wiring complexity, and compatibility with a wide range of Victron energy management tools. It’s a natural fit for users who want dependable dual-battery operation without complicated switching or extra hardware, helping maintain battery health and readiness wherever you install your system.
