REDARC SBI12 Smart Start battery isolator, 12 V, 100 A

The REDARC SBI12 Smart Start is a microprocessor-controlled battery isolator for dual battery systems, working as a solenoid priority system. It protects the start battery from excessive discharge while the auxiliary battery supplies non-essential loads. It runs on 12 V DC and is rated for 100 A continuous.

The battery isolator is mainly used in 4WD and commercial vehicles. Its electronics stop the solenoid from generating high-voltage transients. It does not have the voltage drop of diode-type isolators. Standby current draw is low. Fault detection with an LED indicator warns of over-voltage, voltage drop and excessive current draw. It is a safe way to charge a dual battery system and should be installed with a high-quality fuse kit.
