RV Dual Batteries, Isolators & Relays

Our extensive range features high-quality isolators from reputable brands like Enerdrive, Victron, Projecta, and more. With battery isolators, you can confidently run all your high-powered appliances, such as refrigerators and lights, without the worry of draining your vehicle's starting battery (these isolators are often referred to as a Smart Battery Isolator'). For those with more complex power systems featuring multiple batteries, Caravan RV Camping offers a wide range of top-tier voltage sensitive relays. These intelligent devices ensure optimal battery management by automatically connecting or disconnecting auxiliary batteries based on voltage levels. Our selection includes high-quality relays from Enerdrive, Victron, Projecta, and Baintech.

Are Battery Isolators And Relays Essential?

These devices provide a multitude of benefits that significantly enhance your caravanning or 4WDing experience. Firstly, 12v battery isolators guarantee that your vehicle's starting battery always has enough power to crank the engine, preventing inconvenient situations where you're left stranded due to a flat battery. Secondly, voltage sensitive relays optimise your caravan's electrical system, ensuring all batteries are efficiently charged and protected from over-discharge. This translates to extended battery life and a more reliable power supply throughout your travels.

Caravan RV Camping offers a curated selection featuring unique and innovative features. Our battery isolators boast priority charging, ensuring your main battery receives a full charge before auxiliary batteries are connected. Additionally, an illuminating LED displays the current charging status, providing valuable real-time information. For situations demanding a jump start, a manual override function allows for the temporary paralleling of batteries. Built-in over current and surge protection further safeguard your electrical system from potential damage. To ensure convenient installation, many of the battery isolators we stock come complete with a mounting bracket and screws.

Our voltage sensitive relays are designed for exceptional performance and user convenience. These intelligent devices boast features like zero voltage loss, preventing any power drain while in operation. Models with in-built intelligent battery monitoring systems prevent unwanted switching, ensuring optimal battery health. Voltage dependent switching ensures the relays only activate when specific voltage levels are reached, maximising efficiency. For those seeking a truly modern solution, some models offer a stable wireless connection for remote monitoring capabilities.

Battery Isolators And Relay FAQS:

• 1. What are Battery Isolators?

  Battery isolators switch is designed to safely isolate the start and auxiliary batteries in a dual battery system so you can be confident that your vehicle will start whenever you’re ready to head off again. Battery isolators will protect the starting battery from a low charge in the secondary battery, so it won’t drain the primary battery. By ensuring that no loads are drawn from the vehicle when it’s not in use, you won’t have the stress of a flat battery in the middle of nowhere!

• 2. What Is A Voltage Sensitive Relay?

  A Voltage Sensitive Relay (VSR) is popular in dual battery systems, usually in 4WD vehicles. The VSR is essentially a switch triggered by the input voltage of an electrical current. It’s important to note that it will only work in standard alternator setups. It won’t work on smart alternators because they vary their voltage and won’t trigger the relay properly.

• 3. How Does A Voltage Sensitive Relay Work?

  The voltage sensitive relay is connected from the main battery through a fuse to the auxiliary battery, which will run power appliances like a fridge while you’re camping. When the alternator is running and the voltage builds up, the voltage sensitive relay will cut in at 13.3V and connect the auxiliary battery so both batteries are charged from the alternator. When you turn off the vehicle and the voltage settles down, at 12.7V the relay will cut out, disconnect the auxiliary battery from the main battery so it is isolated. You can drain the auxiliary battery while camping but always be able to start the vehicle and drive away.
