Argodiode 120-2AC 2 batteries 120A Retail

The Argodiode battery isolator provides a reliable way to charge two batteries simultaneously from one alternator or battery charger. Because it uses diode technology, it prevents the current from flowing back from one battery to the other, ensuring your starter battery remains charged even if your auxiliary battery is drained. This unit is built for rugged use in automotive, marine, and off-grid applications. It is easy to install and acts as a solid-state solution to replace mechanical isolators. Please note that this device will cause a slight voltage drop, so we recommend adjusting your alternator charging voltage if possible for optimal performance.
