Balmar Digital Duo Charge 12/24V Battery Combiner for Multi-Bank Charging

Digital Duo Charge - 12/24V

The Digital Duo Charge (DDC-12/24) provides a hands off solution for charging two battery banks without the use of problematic isolators or manual battery switches. During charging the DDC-12/24 monitors voltage at the house battery. When voltage exceeds the set minimum (typically 13.2V in a 12V system and 26.4V in a 24V system) the DDC-12/24 automatically engages, providing up to 30A charge current to the starting battery. When no charge source is present, the DDC-12/24 separates the batteries so the starting battery wont be accidentally discharged into the house battery. An optional solenoid control enables higher start battery charging output when required.

Features:

• Multi Bank Charging


• The DDC is a Solid-State Battery Combiner


• Control Voltage and Current between House and Start Batteries


• Eliminates the Need for an Isolator, Relay or Manually Operated Battery Switch


• Used in Concert with Max Charge or ARS-5 Regulators


• Can also be Employed without a Balmar Regulator


• Works in Both 12V and 24V Applications


• House and Start Batteries can be different technologies


• Start Battery Temperature Sensing Available with the MC-TS-B Sensor Cable


• 4 Battery Programs Supported for the Start Battery:


• Standard Flooded, Deep Cycle Flooded, AGM and Gel Cell

The Balmar Digital Duo Charge (DDC-12/24) offers a reliable and maintenance-free solution for managing multiple battery banks in both 12V and 24V systems. This solid-state battery combiner intelligently monitors the voltage of your house battery, automatically engaging when the voltage exceeds the set threshold—typically 13.2V for 12V systems and 26.4V for 24V systems—delivering up to 30 amps of charge current to the starter battery. When no charging source is detected, the DDC-12/24 isolates the batteries, preventing accidental discharge of the starter battery into the house bank. An optional solenoid control enhances the charging capacity for the start battery when necessary, providing flexibility for various applications and battery technologies. The device supports different battery types, including flooded, deep cycle flooded, AGM, and gel cell, with four configurable start battery programs to optimize charging performance. Compatible with Max Charge or ARS-5 regulators, it can also operate independently without a regulator, making it versatile for diverse electrical setups. Its compact design and solid-state construction ensure durability and ease of installation, reducing maintenance needs. The Balmar DDC-12/24 is an essential component for efficient power management in marine, RV, and off-grid applications, ensuring your batteries are charged safely and effectively without the need for traditional isolators or manual switches. For detailed installation and operation instructions, refer to the manufacturer's manual available online. This product is designed to improve battery management reliability and simplify wiring complexity, providing peace of mind during all your power needs.
