Smart Dual Battery Isolation Controller with Digital Display Voltmeter: Strong waterproof IP68
Ever been stuck with a dead battery in the middle of nowhere? The Smart Dual Battery Isolation Controller is your vehicle's new best friend, keeping the juice flowing where it's needed most. Perfect for ATVs, UTVs, boats, RVs, ships, trucks, and even your home on wheels (looking at you, caravan enthusiasts). At its heart, a power management chip plays the role of a smart gatekeeper, letting the main battery charge the auxiliary one when things look up (voltage above 13.3V) and cutting ties when times are tough (below 12.7V).
Here's the nitty-gritty: it can handle a steady 90-120A, with bursts up to 160A when things get wild. And with an IP68 waterproof rating, it laughs in the face of rain, dust, and whatever else Mother Nature throws at it. Measuring a compact 68x52x68mm, it's small but mighty, designed to keep energy loss low and stay cool under pressure (literally, thanks to its top-notch heat dissipation).
In short, it's built to last and smart enough to make your life easier—no PhD in electrical engineering required.
