Feature: If the voltage is lower than 11.8V, the remote kill will automatically cut off the power supply after 120s to save electricity, if the voltage is higher than 13.2V, the remote control will be disabled to prevent accidental action to shut off the power while driving, and the power supply can only be controlled by the button on the. The remote battery disconnect 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. Designed for 12V power vehicles, this automatic power shut off is a wide range of vehicles including most cars, trucks, RVs, buses, and trailers, specifically those with an engine displacement of less than 3.0. Its versatility ensures broad applicability, providing a reliable power management solution for a vast of vehicle types. The remote control protector is designed for straightforward installation, connecting directly to the battery's negative terminal to ensure stable performance. Remember to turn off the engine before installation to guarantee a safe and efficient setup process. Specification: Rated current:240A Rated voltage:12V Standby power consumption:3mA Power-off threshold:11.8V±0.2V Instantaneous current:1000A Operating Temperature:-20℃-90℃ Color:Black Size:9.3cm/3.66inch x 8.3cm/3.27inch x 3cm/1.18inch Package Included: 1 x Battery Disconnect Power 1pc or 2Pcs x Remote Control Smart Voltage-Controlled Protection: This remote kill features an intelligent voltage-sensing system for dual protection: When battery voltage drops below 11.8V, it automatically cuts off power after 120 seconds to reduce unnecessary energy consumption and protect the battery from over-discharging. When voltage rises * 13.2V (vehicle running state), the remote control function is disabled to avoid accidental power-off during driving. Magnetic Relay Technology: The adopts an innovative magnetic principle relay system to control circuit connection and disconnection, with an -low standby current of just 0.015A. This design significantly improves energy efficiency, avoiding battery drain during long-term parking and optimizing vehicle power management. Extend Battery Lifespan: Effectively prevent battery power loss caused by prolonged parking, aging wiring, forgotten lights, or standby electronic devices. It serves as a reliable safeguard for your car battery, reducing wear and extending its service life. Wide Compatibility: Designed for 12V power vehicles, it is a vast range of models including sedans, trucks, RVs, buses, and trailers—specifically for vehicles with an engine displacement less than 3.0L. Its versatile design meets the power management needs of various vehicle types. Simple & Safe Installation: The remote battery disconnect connects directly to the battery’s negative terminal for stable performance. For safe installation, turn off the vehicle engine first before wiring—no complicated tools required, making it easy to set up even for beginners.
