Product Details

The Blue Sea Systems BatteryLink Automatic Charging Relay (ACR) automatically manages battery charging across multiple battery banks, combining batteries during charging and isolating them when discharging. This intelligent relay eliminates the need for manual battery switches while ensuring both starting and auxiliary batteries remain properly charged.

Superior Charging Performance: Designed for alternators up to 120A, the ACR features one-tenth the voltage drop of traditional battery isolators, delivering up to 60% higher charge rates to your batteries. Dual sensing technology monitors both battery banks and manages multiple charge sources automatically.

Key Features:

  • Automatic dual battery management with dual sensing capability
  • 120A continuous rating, 210A intermittent rating (5 minutes)
  • 12/24V DC voltage input for versatile applications
  • Robust, fully sealed assembly withstands vibration and moisture
  • Integrated LED indicates ACR operating status
  • Optional Auxiliary Battery Priority connection extends auxiliary battery charging time
  • Clip-on cover insulates terminal connections for safety
  • Side and bottom knockouts provide flexible cable routing options
  • Remote LED capability for monitoring ACR status from a distance (requires optional LED)

Technical Specifications:

  • Continuous Rating: 120A | Intermittent Rating: 210A (5 minutes)
  • Voltage Input: 12/24V DC
  • Combine Voltage: 13.6V (30 seconds), 13.0V (2 minutes)
  • Open Low Voltage: 12.75V (30 seconds)
  • Stud Length: 7/8" (22mm) to accept multiple cable terminals
  • Maximum Cable Size: 1/0 AWG
  • Terminal Size: 1/4" × .032" male quick connect terminals for ground and optional features
  • Battery Compatibility: Largest battery bank cannot exceed Group 27

Ideal for marine, RV, and commercial vehicle applications where multiple battery banks require automatic charge management without the voltage loss associated with traditional isolators.
