The REDARC Smart Start SBI12 100A is a 12V DC 100A microprocessor-controlled, dual battery isolator designed to protect the start battery from excessive discharge while allowing the auxiliary battery to supply charge to non-essential loads. For use in multi-battery applications as a solenoid priority system and protecting the start battery from excessive discharge, whilst allowing the auxiliary battery to supply non-essential loads,  the Redarc Smart Start is designed primarily for use in 4WD and commercial vehicles. The SBI2 provides 12 volt DC incorporating 100A of continuous ratings.
The Redarc Smart Start is Australia's most trusted dual battery isolator and is used by 4WD clubs throughout Australia.

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.
