In addition to high output alternators and smart voltage regulators, Balmar offers two valuable additions to your charging system. The Digital Duo Charge and CenterFielder II each provide an effective tool to ensure that all of your vessel's batteries receive optimal charging.
The DDC-12/24 offers the smartest system yet for current and voltage controlled charging between the house and engine starting marine batteries &ldash; eliminating the need for an isolator or battery switches.
During charging, the Digital Duo Charge monitors voltage at the house battery bank. When voltage exceeds the set minimum (typically 13 volts in a 12 volt system, or 26 volts in a 24 volt system), the Digital Duo Charge automatically engages, providing up to 30 amps to the starting battery. When no charge source is present, the Digital Duo Charge separates the battery banks, so the starting battery will not be accidentally discharged.
Optional solenoid control enables higher charging output when required (solenoid is not included). Includes input/output wiring. Preset programs for Gel, AGM, Flooded and Deep Cycle batteries allow mixing of house and starting battery types.
