Victron ArgoFET 200-2 Battery Isolator - 200AMP - 1 Alternator, 2 Batteries

Meet the Victron ArgoFET 200-2 Battery Isolator — the smart, high-current solution for charging two batteries from a single alternator or charger without tying the batteries together. Designed for marine, RV, or off-grid systems, this 200A FET-based isolator delivers simultaneous charging with minimal energy loss.

Thanks to its solid-state FET design, the ArgoFET isolates batteries while preserving maximum charging efficiency. Experience voltage drop that’s significantly lower than traditional diode isolators — less than 0.02 V at low current and around 0.1 V at higher currents. That means more charging power reaches both batteries and better overall battery health.

• Simultaneous charging from one alternator (or single-output charger) to 2 batteries without connecting them in parallel.
• High current capability up to 200A continuous to keep your cranking and auxiliary batteries ready to go.
• Low voltage drop minimizes energy waste and maximizes charging efficiency across the system.
• Solid-state reliability with fast, efficient switching for maintenance-free operation.
• Easy integration with your existing Victron energy setup and standard 12V electrical systems.
