Redarc Smart Start SBI 12V 200A SBI212

$399.00

The REDARC Smart Start SBI212 is a 12V 200A dual sensing battery isolator designed to protect your start battery from excessive discharge while allowing your auxiliary battery to charge. Built for demanding applications like 4WDs, RVs, and marine setups, it automatically connects and disconnects batteries based on voltage levels—no manual switching required.

This compact, rugged isolator is microprocessor-controlled and dual sensing, meaning it can sense charge from both the main and auxiliary batteries, making it ideal for use with solar or external chargers. It ensures your main battery always has enough power to start your vehicle, while your auxiliary battery handles accessories like fridges, lights, or winches.

Made in Australia for harsh conditions, the SBI212 is vibration resistant and suited for under-bonnet installation. It’s the perfect solution for reliable dual battery management on and off the beaten track.

Warranty

Backed by REDARC’s 2-year manufacturer warranty.
