Product Details

The Samlex ACR-160 is a voltage-dependent automatic charging relay designed to intelligently manage dual battery systems in automotive, marine, and RV applications. This smart battery isolator automatically separates or parallels starter and auxiliary battery banks based on voltage levels, ensuring your starter battery is always protected from deep discharge while optimizing charging efficiency.

Key Features:

  • Automatic voltage sensing technology monitors battery voltages and controls connection/isolation
  • Works with both 12V and 24V battery systems for versatile applications
  • 160 amp continuous rating handles high-current charging demands
  • Prioritizes starter battery charging to ensure reliable engine starting
  • Connects batteries in parallel when charging voltage is detected, allowing auxiliary battery to charge
  • Automatically isolates batteries when engine is off to prevent starter battery drain
  • No manual switching required - fully automatic operation
  • Low voltage drop design maximizes charging efficiency
  • No alternator resizing needed - works with existing charging system
  • Solid-state design with no moving parts for reliable operation

The ACR-160 provides a simple, reliable solution for dual battery management without the complexity and voltage drop associated with traditional battery isolators. Ideal for vehicles with auxiliary power needs including work trucks, RVs, boats, and emergency vehicles.

This was my first order from Autoplicity.com. The prices and selection are excellent on the front end and the quick delivery got it to me right on time. I'll definitely be looking here again next time I need parts. Thank you.

It took exactly a week for the part to be shipped because the part came directly from the supplier. But the price was the lowest around.

good
