Product Details

The Blue Sea Systems 8689 Battery Management Panel simplifies battery control for twin-engine marine applications by integrating battery switching, circuit protection, and distribution into a single, compact panel. Designed for boats with dual engines and three battery banks (when used with an Automatic Charge Relay), this panel streamlines electrical system management while protecting sensitive electronics.

Advanced Battery Switching Technology:

The panel features e-Series and m-Series Dual Circuit Plus battery switches that maintain complete isolation between Starting and House circuits. This critical separation protects sensitive electronics from voltage spikes and sags during engine cranking while allowing emergency cross-connecting between battery banks when needed. Both battery banks operate with a single ON position, eliminating complicated switching procedures.

Key Features:

  • Configured specifically for twin-engine marine installations
  • Supports three battery banks when paired with ACR (sold separately)
  • 7-position switching configuration for comprehensive control
  • Dual Circuit Plus switches maintain battery bank separation and protect electronics
  • Emergency crossover feature connects banks during critical situations
  • Built-in DC main circuit breaker with 24-hour branch circuit protection
  • Dedicated circuits for always-on accessories: bilge pumps, CO sensors, stereos, clocks
  • Ignition protected for safe installation on gasoline-powered vessels
  • Four mounting orientations for flexible installation
  • Expandable design with room for additional circuits
  • Backed by Blue Sea Systems lifetime warranty

Technical Specifications:

  • Nominal voltage: 12V DC (maximum 32V DC)
  • Continuous rating: 300A
  • Intermittent rating: 450A (5 minutes)
  • Cranking rating: 1000A (10 seconds), 650A (1 minute)
  • Compact 7.25" × 7.25" panel face with 3.25" depth

This panel replaces discontinued models 8687 and 8691, offering superior performance with modern Dual Circuit Plus technology versus older manual selector switches. Ideal for boat owners seeking professional-grade battery management without complex wiring or multiple component installations.
