Split charge relay kit, 140A VSR 12V Smart Dual Battery Isolator with LED Voltage Display & Manual/Auto Switch. Leisure Charging: Car, RV, Campervan, Motorhome, Caravan, Truck, Marine Boat

【Automated Power Management】 Functioning as a high-capacity split charge relay kit, this unit delivers seamless control over secondary power systems. Rated at an optimal 140A, the integrated voltage sensing relay 12v continuously evaluates system levels, automatically engaging circuits during engine operation and separating them upon shutdown. This mechanism serves as a dependable battery isolator switch 12v, guaranteeing the primary starter cell retains maximum capacity while secondary appliances draw exclusively from the auxiliary source. 【Real-Time LED Telemetry】 Operators are kept fully informed through a high-contrast digital screen engineered directly into this digital voltage relay. The interface delivers instantaneous, live tracking of your electrical network's current status. Operating simultaneously as an active voltage protector relay, this visualized diagnostic tool allows users to verify exact voltage parameters instantly, entirely bypassing the requirement for external multimeters or diagnostic hardware. 【Dual-Mode Circuit Override】 Unlike standard continuous modules, this hardware provides absolute operational control via a physical override configuration. Users can deploy the system as an emergency battery cut off switch for immediate electrical termination. Alternatively, engaging the automated setting provides hands-free circuit separation, while the manual option functions precisely as a direct battery disconnect switch, offering exceptional versatility for complex vehicular architectures. 【IP68 Environmental Shielding】 Constructed to withstand severe elemental exposure, this smart battery isolator is fortified with an IP68-certified chassis, ensuring absolute impermeability against particulate ingress and continuous moisture. Whether deployed deep within a marine engine compartment or mounted on a rugged off-road platform, this car battery isolator switch maintains uncompromised structural and electrical integrity across extreme weather conditions and demanding terrains. 【Streamlined Hardware Deployment】 Engineered with a low-profile physical footprint, the chassis integrates effortlessly into restricted motor bays and confined caravan electrical compartments. It serves as the definitive dual battery isolator kit for both professional installers and individual enthusiasts. Offering universally adaptable mounting configurations, it perfectly functions as a reliable split charger for leisure battery kit deployments in campervans, expedition trucks, and specialized mobile workspaces.
