REDARC Smart Start SBI12 100A Battery Isolator

The REDARC Smart Start SBI12 is a 12V, 100A microprocessor-controlled battery isolator for traditional dual-battery systems.

It protects the starting battery from excessive discharge while allowing the auxiliary battery to supply non-essential loads. The SBI12 automatically connects and disconnects the batteries according to system voltage.
