The Echo Charge digital battery charger is used with an inverter/charger, or other charging source with limited voltage drop to charge auxiliary batteries.
Smart technology allows this charger to realize when the main battery is fully charged. Echo-Charge then redirects a portion of the charge to the starting batteries.
This product is designed to work seamlessly with Xantrex chargers and inverters, and can automatically switch between 12 or 24 volt battery banks. All Xantrex chargers are built with safety in mind featuring built-in thermal, over-current, and reverse polarity protection.
