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.
