Are you tired of dealing with dead batteries on your adventures? Whether you're powering your RV, running electronics on your boat, or keeping your campsite lights on, having reliable dual battery power is essential. This automatic split charge relay kit solves the common problem of battery drain by intelligently managing power distribution between your primary and secondary batteries.
This 12V voltage sense relay (VSR) automatically detects when your main battery is being charged and seamlessly connects it to your auxiliary battery. With a cut-in voltage of 13.3V and cut-out voltage of 12.8V, it ensures optimal charging without overloading either battery. The 5-second delay prevents voltage spikes and protects your sensitive electronics from damage.
Engineered for durability, this kit features IP65-rated protection against dust and water, making it perfect for marine environments, off-road vehicles, and outdoor applications. The M6 stainless steel power studs provide solid, corrosion-resistant connections that stand up to harsh conditions. With a continuous current rating of 140A and intermittent capability of 160A, it handles everything from small electronics to high-draw appliances.
Everything you need for a professional installation comes in the box. You'll get 6 meters of high-quality 110A red battery cable, ground cable, marine battery terminals, fuse holders, lug connectors, and even cable ties and shrink tube for a clean, secure installation. The included drill bit and split conduit make routing the cables through tight spaces effortless.
Whether you're outfitting your RV for extended trips, upgrading your boat's electrical system, or building the ultimate overland rig, this dual battery isolator kit provides reliable, automatic battery management. The low standby current draw of just 8mA means it won't drain your batteries when not in use, giving you peace of mind on every adventure.
