The REDARC Smart Start® SBI12D is a microprocessor-controlled dual battery isolator used in a dual battery system. It’s manufactured for use as a solenoid priority system to protect the start battery from excessive discharge while allowing the auxiliary battery to supply non-essential loads.

Dual sensing

The SBI12D provides 12 volt DC incorporating 100A of continuous ratings and is designed for heavy-duty operations. The dual sensing model is compact and easy to install. It isolates the start and auxiliary battery in a system where the auxiliary battery may be charged by an external source. The SBI12D also allows the start battery to be charged by the external source after the auxiliary battery reaches 13.2V.

Power saving technology

The power saving technology includes fault detection and LED indication of operation to warn users of voltage drops, over-voltage, or excessive current draw conditions. The SBI12D has components that prevent the solenoid from generating high voltage transients. It’s better than a diode battery isolator based on the the voltage drop associated with a diode type isolation.

Surge protection

The SBI12D has full surge protection and is used primarily in 4WD and commercial vehicles. Choose the SBI12D for a safe way to charge an auxiliary battery. The SBI range manages battery charge for your secondary battery banks while on the move.

Features:

  • Overmold design
  • Compact size and easy installation
  • Silver contacts for longer life and suitable for marine applications
  • Power saving technology
  • Fault indication
  • Fully surge protected

    if you are going to be moving them a lot, buy something more sturdy.
    Color: Black, Size: Wheel-6 Panel
    I use these at our churchc. They are pretty good, not terribly study and the screw that hold the faabric have pulled out in a couple of places. But they wqould work especially well if you were not constantly moving them as we do. They are a bit of a pain to assemble.

    Super Low Quality/Unacceptable QC
    Color: Black, Size: Wheel-6 Panel
    I spent probably about an hour putting it together, only to take it right back apart and pack it up to return. The dimples for half the poles were on the wrong side (double and triple checked to make sure they couldn't be spun around. The threaded ends for the wheels were freely spinning on all but 2 wheels, making it impossible to actually tighten them fully. Once it was all put together, the screens could not be folded up to neatly put it aside when not in use. All in all, this was shamefully low quality for the money spent.
