BalDC01	Digital Duo Charger charges starting battery from house bank. by Balmar Acts like a combiner with a regulated charge.	$201.95	View Cart

The Digital Duo Charge provides a safe, intelligent alternative for the care of your vessel’s engine starting battery. Unlike switches, isolators and other charge splitting devices, the Duo Charge is mounted between the vessel’s house and starting batteries rather than between the alternator and batteries. This allows the alternator and regulator to concentrate output based on the house battery’s needs. When the Duo Charge senses charging voltage at the house battery, it works like a DCto- DC battery charger, providing up to 30 amps of regulated charging current to support the starting battery. In most installations, the Duo Charge requires just four wires for operation; a fused input wire, a fused output wire, a ground wire and an ON/OFF wire. In applications where the Duo Charge is used to supply a battery bank that may require more than 30 amps of regulated charging current, the Duo Charge may be used to manually control an external solenoid. Please note the section in the manual relating to solenoid control. The Duo Charge is designed specifically to enable its user to control charging voltage output -- making it possible to safely mix house and starting battery technologies. The Duo Charge features four different programs based on four battery technologies: Standard Flooded, Deep Cycle Flooded, Gel and AGM battery types. In addition, the Duo Charge can be programmed for 12-volt or 24-volt operation. When used with an optional Battery Temperature Sensor cable (MC-TS-B), the Duo Charge has the ability to respond to a battery over-temperature condition by automatically discontinuing charging output.
