This automatic battery splitter protects your starting battery while ensuring auxiliary loads get charged when the engine is running. It automatically combines two batteries during charging and isolates them when not charging, so you never have to choose between a ready-to-start engine and a fully powered camper, boat, or leisure setup. Built for rugged environments, it’s ideal for camper vans, 4x4s, leisure vehicles, and marine applications. You’ll enjoy minimal voltage drop compared with diode-based isolators, thanks to a design that avoids the common 0.6V loss. The robust glass fiber reinforced nylon enclosure, IP67 protection, and ISO8846 ignition protection make this unit reliable in engine compartments and harsh outdoor conditions. A built-in LED indicates when the VSR engages, and you can choose surface or panel mounting for flexible installation. An optional Storage Mode helps eliminate standby power draw when the engine is off, preserving battery life for extended off-grid use.\u003c\/p\u003e \u003ch3\u003eBenefits \u0026amp; Tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eEffortless dual-battery management: let the device automatically connect batteries during charging and isolate them when not charging, keeping the starter battery safe while maximizing auxiliary power.\u003c\/li\u003e \u003cli\u003eReliable for off-road and marine use: designed for camper vans, boats, and leisure vehicles, with ignition protection and waterproof housing to stand up to engine compartments and wet environments.\u003c\/li\u003e \u003cli\u003eFlexible installation and low idle draw: surface or panel mounting options, M6 terminals, and a low standby power draw (10 mA) make setup clean and efficient.
