Voltage Sensitive Relays (VSRs)

2 Products Found

Keeping your vehicle powered off-road or on long trips is all about balance - you want to run your accessories without worrying about draining your starting battery. That’s where VSRs (voltage-sensitive relays) come in. 

Designed to manage your dual battery setup, these smart devices automatically control when your auxiliary battery charges and disconnects, making sure your starting battery stays charged and ready to go. At Offroad Living, we understand the importance of a high-quality power setup, which is why we offer the best VSRs in Australia.

Don’t Risk Draining Your Starting Battery

When you’re off-grid, a dead starting battery isn’t just inconvenient. It can easily leave you stranded. A VSR solves this by automatically engaging and disengaging based on voltage levels. Once your starting battery reaches a safe charge level (typically around 13.2V), the relay activates, sending power to your auxiliary battery. 

If the voltage drops (below 12.8V), the VSR disconnects, prioritising your starting battery and preventing accidental discharge. This makes a voltage-sensitive relay a smarter, safer alternative to old-school diode isolators, which suffer from voltage drops and inefficiencies. With a VSR installed, you can confidently power your fridge, lights, and accessories without sacrificing the ability to start your engine.

Australian-Quality 12V and 24V Relays

Whether you’re setting up a 4WD, camper, or marine rig, having the right VSR for your system is crucial. Our high-quality 12V relays are Australian-made and perfect for our typical off-road setups, camper vans, and RVs, ensuring reliable dual battery charging while you run gear like fridges, lights, or inverters. 

For larger vehicles, boats, or commercial setups, our heavy-duty 24V relays handle higher loads - ideal for trucks, buses, and marine systems. Built to withstand the tough conditions you’ll encounter, these relays offer no-fuss reliability, so you stay powered, no matter how rough the road (or water) gets.
