Blue Sea Systems 8686 Dual Bank Battery Management Panel Single Engine

The Blue Sea Systems 8686 Battery Management Panel simplifies marine electrical systems by integrating battery switching control and circuit protection into a single, compact unit. Designed specifically for single-engine boat configurations, this panel features dual circuit battery switches that isolate starting and house circuits while protecting sensitive electronics from voltage spikes during engine cranking.

Key Features:

• Dual Circuit Plus battery switches maintain battery bank separation with simplified single ON position operation
• Emergency crossover feature allows connecting separate battery banks when needed
• Protects electronics from current surges and voltage sags caused by engine starts
• Integrated DC main circuit breaker with 24-hour branch circuit protection for bilge pumps, CO sensors, and other non-switched accessories
• Ignition protected design certified for installation on gasoline-powered boats
• Supports 2 battery banks with optional Automatic Charge Relay (ACR) integration
• Can be mounted in four different orientations for flexible installation
• Room for expansion to add additional circuits as needed
• Replaces discontinued models 8687 and 8691
• Backed by lifetime warranty

Technical Specifications:

• Nominal voltage: 12V DC (maximum 24V DC)
• Continuous rating: 300A
• Intermittent rating: 500A (5 minutes)
• Cranking rating: 1500A (10 seconds), 775A (1 minute)
• Dual circuit battery switches with 4 positions
• Panel dimensions: 7.5" H × 4.5" W × 3.25" D

This battery management panel is ideal for boat owners who want reliable, organized electrical system control without the complexity of managing multiple separate components. The integrated design reduces installation time and ensures proper circuit protection for both critical and auxiliary systems.
