REDARC Smart Start Battery Isolator Dual Battery System

The REDARC Smart Start Battery Isolator is a microprocessor-controlled dual battery isolator for dual battery systems. It works as a solenoid priority system. It protects the start battery from excessive discharge. The auxiliary battery can still supply power to non-essential loads such as accessories, fridges and lighting. It is also known as a dual battery controller or battery isolator solenoid.

Key Features:

• Microprocessor-controlled solenoid priority design that keeps the vehicle's start battery from being drained by auxiliary loads
• Electronic components that prevent the solenoid from generating high voltage transients
• Avoids the voltage drop of a diode-type isolator, so it charges the auxiliary battery more efficiently
• Fault detection with LED indication, which warns of voltage drops, over-voltage and excessive current draw
• Low standby current draw and power-saving technology
• Full surge protection
• Silver contacts for long life, suitable for marine applications
• Compact over-mold construction for easy installation
• Dual sensing versions are available. They isolate the start and auxiliary batteries when the auxiliary battery is charged from an external source, such as solar panels or an AC battery charger. They also let that source top up the start battery.

The Smart Start range is used mainly in 4WD, commercial, RV and marine applications. Choose the model in the line that matches your charging setup and current requirements.
