Power Switch Feature: Magnetic Lock Feature: The remote battery disconnect switch utilizes an innovative relay system based on magnetic principles to control the connection and disconnection of circuits. With a standby current of just 0.015A, it significantly enhances energy efficiency, making it an ideal solution for optimizing vehicle power management. Versatile Compatibility: Designed for 12V DC power vehicles, this automatic power shut off switch is compatible with a wide range of vehicles including most cars, trucks, RVs, buses, and trailers, specifically those with an engine displacement of less than 3.0. Intelligent Automatic Disconnection: The car remote battery cut off switch features an automatic disconnection function that activates if the battery voltage drops below 11.8V. It automatically cuts off power within 120 seconds to conserve energy. Conversely, when the voltage exceeds 13.2V, the remote control becomes inactive to prevent accidental power cuts while driving,
