Meet a compact, robust battery management solution designed for space-conscious boats. The Blue Sea Systems 7649 Mini Add-A-Battery kit delivers automatic coordination for two battery banks with a 65 A continuous rating, making charging and switching simpler in tight helm spaces and smaller installations.

Smart features that matter

  • Automatic charging relay that senses charge voltage, combines batteries during charging, and isolates them at rest
  • Mini Dual Circuit Plus switch that controls starter and house banks independently for compact two-bank setups
  • Emergency parallel function that links batteries when needed to support engine starting
  • Space-saving installation designed to fit in tight helm areas and reduce wiring complexity
  • Marine-rated components with tin-plated copper studs for durability in harsh environments

Real-world use and benefits

On a small runabout or coastal cruiser, this kit helps keep critical systems powered while minimizing clutter. Sailors and weekend boaters benefit from a streamlined wiring approach and the ability to manage two banks without a bulky control panel.

  • Two-bank operation without a large single-switch setup
  • Automatic battery coordination during charging to maximize available power
  • Isolating banks when idle reduces the risk of unintended discharge
  • Emergency link to assist engine starting if one bank is weak

The rugged construction and corrosion-resistant components are designed for saltwater environments, making this kit a practical choice for small boats that value reliability and efficient space use. Installation guidance and battery compatibility considerations are important to ensure optimal performance in your specific setup.
