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.
