What does a smart battery isolator do?

When batteries reach 12.7V, the Smart Battery Isolator senses it, opens the solenoid relay to separate the battery banks, and turns off the status light. This protects the starting battery while allowing the auxiliary battery to continue to power the auxiliary loads.

What is a smart isolator?

A smart isolator is the ultra-simple and most technologically advanced method of automatic battery isolation. These units can be installed between batteries with a common ground to automatically control the charging process to the batteries but continue to provide isolation when a charging source is unavailable.

How does a Redarc battery isolator work?

The Redarc SB12 Dual Battery Isolator uses a microprocessor-controlled solenoid to protect your car’s starting battery from deep discharge while allowing your second deep cycle battery to power all non-essential loads including fridges, lights and all your other on-board 12V accessories.

Should I use a battery isolator?

A battery isolator helps to ensure that the starting battery has sufficient power to start the engine and recharge the batteries if, for example, loads on the auxiliary battery (e.g., refrigerator or navigation lights) cause it to be drained, or if an auxiliary battery fails.

What is the yellow wire for on a smart battery isolator?

manual bypass
The yellow wire is a manual bypass to trigger the isolator. This is not required as the isolator switches automatically based on voltage.

Do you need an isolator for dual battery?

A Dual Battery System will isolate the second (auxiliary) battery from the starter battery. You might only need something as simple as the Smart Solenoid or smart battery isolator. These allow you to charge your second battery while you drive, while also protecting your starter battery from excessive discharge.

Do you need a battery isolator?

Can you run 2 batteries without an isolator?

There are two different ways to isolate the batteries. First I should say that “yes” it will work without an isolator. You can directly put them together this way. The problem is you’ll shorten the life of the batteries due to the capacitance and discharge rate differences.

How does a smart isolator battery charger work?

How it works: The smart isolator allows two batteries to be charged at the same time. When the engine is started and either battery reaches 13.4 volts, the relay engages, allowing two battery banks (start and accessory) to be charged simultaneously.

How is the REDARC smart battery isolator ( SBI ) used?

The REDARC Smart Start® SBI is designed to be used in multi-battery applications as a solenoid priority system to protect the start battery from excessive discharge, while allowing the auxiliary battery to supply non-essential loads.
