The REDARC Smart Start® SBI12 is a 100A 12V microprocessor-controlled battery isolator which protects the start battery from excessive discharge, while allowing the auxiliary battery to supply charge to non-essential loads.
The battery isolator is mostly used in 4WD and commercial vehicles. It incorporates electronic components that prevents the solenoid from generating high voltage transients. Due to the voltage drop associated with diode type isolation, it’s better than a diode battery isolator. A low standby current draw and fault detection and LED indication of operation warns users of faults such as voltage drops, over-voltage, and excessive current draw conditions. Safely maintain the charge your dual battery system with the Smart Start SBI12 battery isolator.
For help in choosing the best dual battery setup for your needs, use REDARC’s vehicle selector tool.
