REDARC Smart Start Battery Isolator & Wiring Kit 12V

Build a dependable 12V dual battery system with the REDARC Smart Start® Battery Isolator & Wiring Kit. Featuring the proven Smart Start® SBI12 100A battery isolator along with the essential wiring and installation components, this complete kit simplifies dual battery installation while protecting your starting battery from excessive discharge.

Designed for overland vehicles, 4WDs, work trucks, RVs, and marine applications, the SBI12KIT automatically isolates the starting battery from auxiliary loads.
