Blue Sea Systems 7611BSS BatteryLink ACR Automatic Charging Relay

The Blue Sea Systems 7611 BatteryLink ACR (Automatic Charging Relay) is an intelligent battery management solution that automatically shares a single charging source between two battery banks. This advanced relay senses when either battery bank is receiving a charge and automatically connects the batteries to distribute charging power, then isolates them when charging stops to prevent drain from non-essential loads.

Key Features:

• Automatic voltage sensing on two independent battery banks
• Optional auxiliary battery priority feature for prioritized charging
• Integrated LED status indicator shows ACR operational status at a glance
• Side and bottom cable entry knockouts provide flexible installation options
• Heavy-duty threaded studs accept multiple cable terminals for versatile connections
• One-piece stainless steel flange nuts ensure corrosion-resistant, secure connections
• Clip-on insulating cover protects terminal connections from accidental contact
• Quick-connect terminals simplify ground and optional feature wiring

Ideal for marine, RV, and commercial vehicle applications where multiple battery banks need intelligent charge management. The BatteryLink ACR eliminates the need for manual battery switches while ensuring both starting and house batteries stay charged. Perfect for boats with separate engine start and house battery systems.
