What Are VSRs and How Do They Operate?

A Voltage Sensitive Relay (VSR) is an automatic switch that connects and disconnects the main and auxiliary batteries based on voltage levels. When your vehicle’s engine is running and the alternator is charging, the VSR senses the increased voltage and links the batteries to enable charging. When the engine is off and the voltage drops, the VSR disconnects, ensuring your starter battery isn't drained by accessories.

KickAss VSRs feature dual-sensing capabilities, allowing them to detect voltage from both batteries, ensuring efficient charging from any power source - alternator, solar, or otherwise.

What Are LVDs and How Do They Function?

Low Voltage Disconnects (LVDs) protect your battery system by monitoring voltage levels and disconnecting the load when it drops too low, preventing deep discharges that can damage your battery. For example, if you’re running appliances like fridges or lights off your secondary battery, an LVD will cut power before the battery voltage becomes critically low. KickAss LVDs are designed to reconnect automatically once the voltage recovers, maintaining protection without the need for manual resets.

Why You Need Battery Isolators

1. Protect Your Starter Battery: VSRs keep your starter battery isolated when the vehicle is off, ensuring it stays charged and ready to start the engine.

2. Extend Battery Lifespan: LVDs prevent your batteries from discharging too deeply, reducing wear and minimizing the need for replacements.

3. Simplify Power Management: VSRs automatically manage charging between batteries, offering an efficient and hassle-free setup.

4. Optimize Off-Grid Power Distribution: VSRs and LVDs ensure safe and effective power distribution, whether charging from the alternator, solar panels, or other sources.

Choosing the Right Isolator

Choosing the right isolator depends on your system's needs. Understanding and using VSRs and LVDs can significantly enhance your off-grid experience by providing reliable and efficient power management. Explore the KickAss range to find the ideal fit for your setup.
