Product Details

The REDARC SBI12 Smart Battery Isolator is a voltage-sensitive relay (VSR) designed to manage dual battery systems in 12-volt automotive, marine, RV, and off-road applications. This 100-amp isolator automatically connects and disconnects auxiliary batteries based on voltage levels, ensuring your starting battery remains charged while powering accessories from a secondary battery.

Key Features:

  • 100-amp continuous current rating for high-demand applications
  • Voltage-sensitive operation automatically connects at 13.3V and disconnects at 12.8V
  • Bi-directional charging allows both batteries to charge from alternator or external sources
  • Compact, weatherproof design suitable for engine bay installation
  • No voltage drop between batteries when connected for maximum charging efficiency
  • Built-in surge protection and thermal overload protection
  • Simple two-wire installation with no manual switching required
  • Compatible with standard lead-acid, AGM, gel, and calcium batteries

Ideal for vehicles with auxiliary lighting, winches, refrigerators, inverters, or other accessories that require a dedicated battery system. The smart isolator protects your main battery from discharge while ensuring reliable starting power. Australian engineered and manufactured by REDARC for extreme operating conditions.

Thanx

Good

It was very quick and easy to find the part I was looking for.

Fast and easy

easy to navigate website, quick checkout AND terrific prices

Compared to other auto parts sites (Summit, JEGS, etc.) not only was shipping to Hawaii half the cost, but the product itself was cheaper too!

Placed order on 4/23. Autoplicity sent an email on 4/25 saying product was shipped (it wasn't), tracking # was blank. Actual shipping label was created on 4/29 and finally received on 5/5. That's 13 days for delivery. Unacceptable. Product pricing was the best I could find. I'll buy from them again, but I can't be in a hurry.

Was never sent tracking info. But fast shipping. Said product will fit my truck. Does not fit 2012 f150 cup holders.
