Smart Start SBI 12V 200A - By RedARC

$223.74 USD $269.99 USD


The REDARC Smart Start® SBI212 is a battery isolator used as a solenoid priority system to protect the start battery from excessive discharge while the auxiliary battery is supplying non-essential loads. It provides 12-volt DC with the incorporation of 200A of continuous ratings.

The SBI212 is designed for extremely heavy-duty operations. It’s primarily used in commercial vehicle dual battery systems. It incorporates electronic components to prevent the solenoid from generating high voltage transients. It is better than a diode battery isolator due to the voltage drop associated with diode type isolation.

Its low standby current draw and sophisticated fault detection and LED indication of operation warns the user of faults including over-voltage, voltage drop, and excessive current draw conditions.

The Smart Start SBI battery isolator is a safe way to charge dual battery system. The SBI range manages battery charge for your secondary battery banks to 100% state of charge and provides power saving technology and ultimate performance.
