Unlock Reliable Power: A Deep Dive into the Redarc Smart Start SBI12 100A Dual Battery Isolator for 4WD & More

Embarking on an off-road adventure or running essential accessories in your commercial vehicle demands a reliable power source. A dual battery system is key to maintaining power for your fridge, lights, and other electronics without draining your start battery. This is where the Redarc Smart Start SBI12 100A dual battery isolator steps in, offering an intelligent and robust solution for auxiliary battery charging.

What is a Dual Battery Isolator and Why Do You Need One?

A dual battery isolator is a critical component in any dual battery system, designed to manage the charging of your auxiliary battery from your vehicle's alternator while protecting your primary start battery. It ensures that your starter battery always has enough power to crank your engine, even if you’ve run your auxiliary battery flat. Without a quality isolator, you risk being stranded with a dead main battery after using your accessories.

Introducing the Redarc Smart Start SBI12 100A Dual Battery Isolator

The Redarc SBI12 is a microprocessor controlled isolator, setting it apart from simpler solenoid-based systems. This advanced unit acts as a 12V battery isolator that automatically disconnects your auxiliary battery from your start battery when the vehicle is off. When the engine starts and the start battery reaches a specific voltage (typically 13.2V), the SBI12 intelligently connects the auxiliary battery for charging. It then disconnects when the voltage drops to 12.7V, ensuring complete start battery protection.

This 100A continuous current isolator boasts a rugged overmould design isolator, compact battery isolator dimensions, and uses high-quality silver contacts isolator for maximum reliability. As a proud Redarc Australian made product, you can trust its quality dual battery isolator construction and performance.

Key Benefits for Your 4WD, Commercial Vehicle, or Marine Setup

• Reliable Power: Perfect for 4WD dual battery systems, this 12V system isolator ensures your camping fridge, lights, and other accessories have dedicated power.
• Start Battery Protection: Guarantees your primary battery is always ready to start your engine, preventing frustrating breakdowns.
• Intelligent Operation: Its power saving isolator features and low standby current isolator ensure efficient energy management.
• Durability: Built for harsh conditions with surge protected isolator capabilities and high voltage transient prevention.
• Versatility: An excellent choice for a commercial vehicle battery isolator or even a marine battery isolator, thanks to its robust design.

How the SBI12 Provides No Voltage Drop Charging

Unlike some diode-based isolators that can cause a voltage drop and less efficient charging, the Redarc Smart Start SBI12 acts as a no voltage drop isolator. This means your auxiliary battery receives optimal charging directly from the alternator, leading to faster and more complete charging cycles. Its sophisticated microcontroller monitors both battery voltages, ensuring seamless and safe operation.

Installation Tips and Essential Accessories

When installing your Redarc SBI12, proper wiring and protection are crucial. Always refer to the SBI12 instruction manual for detailed steps. To ensure maximum safety and performance, you'll need a quality dual battery wiring kit and appropriate fusing. A Redarc fuse kit, such as an 100A Midi Fuse Kit, is essential to protect your wiring and the isolator itself from short circuits or overcurrents. We stock various options including FK60 and FK100 fuse kits designed to complement your Redarc setup.
