Product Description

The REDARC SBI12 Smart Start® Battery Isolator is engineered to optimize dual battery systems by automatically linking batteries during charging and isolating them when voltage drops. This ensures your primary (starter) battery is always prioritized, preventing unwanted discharge while still allowing the auxiliary battery to run accessories.

Unlike traditional diode isolators, the SBI12 uses a solenoid-based system, eliminating voltage drop issues and delivering more efficient charging performance. Its advanced electronics suppress voltage spikes, protecting sensitive equipment and extending system lifespan.

Ideal for off-road vehicles, RV setups, and commercial applications, this isolator offers a robust, compact, and intelligent solution for managing multiple batteries.
