Redarc SBI24 Smart Start Dual Battery Isolator 24V 100A
The Redarc Smart Start SBI24 is a microprocessor-controlled battery isolator for 24 V dual battery systems, rated at 100 A continuous. It parallels the starting and auxiliary batteries while the alternator is charging and automatically separates them when the voltage falls.
Built for trucks, work vehicles, motorhomes and boats with 24 V electrical systems: non-essential loads run from the auxiliary battery without ever compromising engine starting. Designed and manufactured in Australia.
