Product Details

The Bluewater 9800-7101-00 Automatic Charging Relay (ACR) is an intelligent battery management solution designed for marine and RV dual battery systems. This advanced relay automatically manages battery charging to ensure maximum efficiency while protecting both starter and house batteries from over-discharge.

Key Features:

  • Automatic Battery Management – Connects batteries during charging and isolates them when voltage drops, ensuring each battery maintains optimal charge
  • Start Isolation (SI) Protection – Protects sensitive electronics during engine cranking by temporarily disconnecting house loads, indicated by a slow-flashing yellow LED
  • High-Output Support – Compatible with alternators up to 120 amps continuous (140 amps intermittent)
  • Dual-Color LED Status Indicators – Provides real-time battery status including Fault, Charging, Discharging, Combine, SI, and Override modes
  • Under Voltage Lockout – Prevents the relay from closing when battery voltage is too low (9.5V for 12V systems, 19V for 24V systems)
  • Marine-Grade Durability – IP67 waterproof rating, ignition protected, safe for gasoline-powered boats and RV applications

Technical Specifications:

  • Continuous Rating: 120 Amps
  • Intermittent Rating: 140 Amps
  • Maximum Voltage: 48VDC
  • Recommended Cable Size: 4/0 AWG

Ideal for boats with dual battery systems, fishing boats with trolling motors, RVs with house and chassis batteries, and any application requiring intelligent battery isolation and charging management.

Good experience

Outstanding product and fast delivery. I will continue buying from this company..

Thank you. You are cheaper than West Marine Pro, (although I have to pay shipping,) and faster than Amazon. My poor planning of immediate boat projects, and your products and ease of ordering and two day delivery work well.

Had what I needed and easy to checkout.

Great

Quality product just as advertised quick shipping. No problem it fits Sammy out.

You have the part I need while other auto part stores didn&amp;#039;t. Great!

Ordering went smooth, good prices. Hope everything else goes well.
