Dual Battery Isolators manual

The REDARC Smart Start® SBI2 is a microprocessor-controlled battery isolator used in dual battery systems as a solenoid priority system. It will protect the start battery from excessive discharge, whilst allowing the auxiliary battery to supply non-essential loads. The SBI2 provides 12 volt DC incorporating 100A of continuous ratings.

Power Saving Technology

The battery isolator is primarily used in 4WD and commercial vehicles and incorporates electronic components that will prevent the solenoid from generating high voltage transients. It is better than a diode battery isolator due to the voltage drop associated with diode type isolation. It features a low standby current draw and sophisticated fault detection and LED indication of operation to warn the user of faults including over-voltage, voltage drop and excessive current draw conditions.

The Smart Start SBI12 battery isolator is a safe way to charge a dual battery system and should often be installed with a high quality fuse kit.

Features

Overmould design
Compact in size and easy to install
Silver contacts for longer life and suitable for marine applications

Redarc SBI12

I first installed a Redarc SBI12 dual battery isolator in my 2003 Toyota Hilux where it performed faultlessly until the car was written off (damned horses!).
Its replacement vehicle, a 2014 Isuzu Dmax was also equipped with an SBI12. THe DIY install was easily undertaken, with simple and clear instructions that DIY's of even limited experience could follow. We also installed the dual battery connect button to link the batteries if the main battery failed - this happened out bush (as it always does!) when my cranking battery dropped a cell, and had to start the car for three days by pressing the button. Ive found the SBI12's to be basic but extremely reliable and very effective in what they do. Highly recommend these units.

Best of the best

I have had the SBI in the vehicle now for a few months. I installed it 'temporarily' for a hasty mission of 2 weeks in the north island and it performed amazingly well.
Highly highly recommend to anyone looking into building a 12v setup. This is perfect to install in an afternoon and last a lifetime.
