A recreational vehicle implies a broad use of various equipment responsible for comfort and safety. This may include interior or exterior lights, refrigerator, cooktop, computer, water pump, and other amenities that have one thing in common – they need electricity. One battery is usually not enough to cover all the needs in electricity when a camper stays unplugged to the AC network, so many RVs have two or even more batteries one of which should always be ready to crank the engine. If you want to optimize the performance of your electrical system, you're likely to need a special solution, and you can find it in our online store.
In our collection of RV battery guards, you can choose from battery isolators, combiners, relays, and other devices. As the name implies, the isolator is responsible for isolating the cranking battery from electrical consumers when it's not charging, to keep it ready to start the motor no matter what. Also, it allows for charging two or more batteries from one alternator without connecting the batteries to each other. Some other devices offered here work as a switch that automatically disconnects the battery from auxiliary systems before its voltage drops below a critical (preset) level. With the help of our products, your RV electrical system will work in a safer, more intelligent way.
