12V car battery intelligent power-off switch, with both remote control and manual control functions, capable of handling a maximum current of 240A. The pure copper connectors ensure stable conductivity and low power consumption during standby. It automatically cuts off power when the battery is low or there is leakage. Comes with two remote controllers, easy to install, suitable for cars, campers and trucks, providing long-term protection for the vehicle's electrical circuits and batteries.

The device is equipped with an ON/OFF physical button, allowing you to turn on or off the power supply locally without the need for a remote control. It comes with two wireless remote control keys, enabling one-click power on/off from a distance. You don't have to bend over to open the hood. When parking for a long time or going on a business trip, the remote control can cut off the battery circuit remotely, completely solving the problem of static power consumption of the vehicle and electrical leakage causing the battery to run out of power and fail to start. During daily circuit maintenance, it can also quickly cut off the power supply, enhancing safety during repairs. The remote control signal is stable, and it can be detected normally both inside and outside the vehicle. It is convenient and effortless to use.This intelligent battery main switch is compatible with 12V vehicles and supports dual control via wireless remote control and on-board buttons. It can handle a maximum current of 240A and can cut off the vehicle's power supply when parked for a long time to prevent battery leakage and depletion. It offers both vehicle protection and convenient operation. It can be used for private cars, modified vehicles, campers, and trucks.
With a 240A current capacity, the pure copper connectors ensure stable conductivity.
The wiring terminals use thickened pure copper plated gold clips, which have strong conductivity, low internal resistance, and are not prone to overheating or oxidation. They can withstand the high current during startup without getting hot or burned. It is compatible with 12V cars, SUVs, campers, construction machinery, and agricultural vehicles, meeting the power supply needs of original vehicle electrical systems and vehicle modification equipment with high power requirements. The metal wire clamps bite firmly and install tightly on the battery terminals, and they won't loosen or fall off in bumpy road conditions. It eliminates the risk of false connection and overheating.
Multiple intelligent protections provide long-term protection for the battery and circuits.
An internal low battery monitoring mechanism automatically disconnects the circuit when the battery voltage is too low to prevent deep battery depletion and damage to the battery life. It comes with a magnetic locking structure that keeps the circuit disconnected after power loss and avoids accidental re-connection due to vehicle vibration. The entire machine has low power consumption and standby mode, with an ultra-low static power consumption of 3mA, and the switch itself hardly consumes the battery's power. The casing is designed with a sealed dustproof and waterproof design, allowing it to work stably in damp and dusty engine compartments, and it is resistant to high and low temperatures without malfunctioning.
Installation is simple, and it is compatible with the vast majority of 12V vehicles.
It can be directly connected in series to the negative terminal of the battery without modifying the original vehicle wiring. Just tighten the clips with your hands to complete the installation. Even beginners can operate independently. The device comes with an indicator light that shows the battery's voltage level in real time, allowing you to intuitively grasp the battery's condition. It is highly suitable for scenarios such as long-term vehicle parking, adding multiple electrical appliances for modification, and severe leakage in old vehicles. It can prevent battery depletion and breakdown, reduce the risk of circuit short circuits and self-ignition, and is a practical accessory for long-term vehicle protection.
Suitable for multiple scenarios, a necessary and safe accessory for vehicle use
It can be used for daily short-distance commuting, long-distance business trips, long-term vehicle parking, outdoor campers, and storage of construction machinery. One switch can fulfill the triple functions of leakage protection, depletion protection, and circuit maintenance power-off. Remote control operation eliminates the hassle of frequently opening the engine compartment. The pure copper high-current structure is compatible with various modified high-power equipment, balancing practicality and safety. It safeguards the battery and the entire vehicle circuit.
