Product Details

The REDARC Smart Start SBI12D is a microprocessor-controlled dual battery isolator designed to protect your start battery from excessive discharge while allowing the auxiliary battery to supply non-essential loads. This unit provides 12 volt DC with 100A continuous rating and is designed for heavy-duty operations in a compact, easy-to-install package.

Key Features:

  • Dual sensing technology isolates start and auxiliary batteries in systems where the auxiliary battery may be charged by an external source, and allows the start battery to be charged by the external source after the auxiliary battery reaches 13.2V
  • Power saving technology with fault detection and LED indication warns users of voltage drops, over-voltage, or excessive current draw conditions
  • Electronic components prevent the solenoid from generating high voltage transients
  • Overmold design with silver contacts for longer life and suitable for marine applications
  • Full surge protection ideal for 4WD and commercial vehicles
  • Automatically connects auxiliary battery to charging system when start battery reaches 13.2 volts, then isolates when system drops to 12.7 volts

This smart battery isolator is superior to diode-type isolators due to the voltage drop associated with diode type isolation. The unit includes an override function capability that allows you to link batteries together via a push button for emergency starting or winching operations. Professional installation by a qualified auto electrician is recommended, and REDARC suggests using MIDI fuses with a quality fuse holder for proper installation.
