Description
Victron Argo Diode Battery Isolator is a 160A dual-battery charging solution designed to let a single alternator charge two independent batteries without cross-connecting them. Ideal for marine, automotive, and off-grid setups, it keeps your starting battery ready while powering accessory loads.
- Current rating: 160A maximum pass-through for dual-battery charging from a single alternator.
- Independent charging: Simultaneous charging of two batteries from one alternator without connecting the batteries together, so discharging the accessory battery won’t drain the starter battery.
- Low voltage drop: Schottky diodes deliver approximately 0.3 V at low current and about 0.45 V at the rated output, improving charging efficiency.
- Compensation diode: Included to slightly raise the alternator output and offset diode losses for better overall charging performance.
- Durability: Built for durability and safety in marine, automotive, and off-grid applications.
- Ideal applications: Perfect for boats, RVs, and other vehicles where two independent batteries need charging from a single alternator without cross-connection or over-discharging.
- Safety & compliance: Includes Prop 65 warning; consult California.gov for details.
- Manufacturer & warranty: Victron Energy; Part No ARG160201020; UPC 8719076019114; warranty and support handled through your Victron dealer.
With the Argo Diode Isolator, you gain reliable power when you need it most: your starting battery remains charged while the accessory battery powers auxiliary loads, reducing the risk of a dead engine and keeping critical electronics ready. This setup is especially beneficial for boats, RVs, and off-grid scenarios where a single alternator serves multiple batteries without cross-connecting or unnecessary discharging.
