Smart Battery Disconnect Switch with Digital Voltmeter for Vehicles

KTNNKG Remote Car Battery Disconnect System: When you leave the car for a long time, the battery is still working... kill your car power system with a remote control now.

Handy, easy, and simple - this Remote Control Electromagnetic Battery Switch allows you to move the trigger from under the hood to your hand.

Smart Voltage Kill Switch: The LCD display of the battery kill switch detects the voltage at all times. In smart mode, when the battery voltage is lower than 12.2V, the switch will automatically turn off after 3 minutes; when the battery voltage is higher than 13.2V (for example, when you are driving), the remote will not control the switch.

Please check the car hood space and voltage of the car battery (12V only) before purchase. This remote battery switch is only for battery on/off, it can't start your engine. Do not turn off the battery when your engine is working.

The standby current of this car kill switch anti-theft is only 0.003A, which is far lower than the standby current of the original car, which is more than 60 mA. It will not drain your battery. The default off design ensures that the device is in a closed condition if the battery were dead.

Why do we need this device? 1. Sometimes, we park our car in one spot for long periods (15 days or more), and the car battery runs down day by day. This device can cut the power off, and you just need to turn on the battery with your remote whenever you want to use the car. 2. A thief can't start your car without the remote. 3. In smart mode, when the battery voltage is lower than 12.2V, the switch will automatically turn off after 3 minutes; when the battery voltage is higher than 13.2V (including 13.2V, for example, when you are driving), the remote control will stop working.

Notice: 1. This device is for battery on and off only, it can't start your engine. 2. Do not cut the power off when your engine is working. 3. The remote has been paired properly with the switch, you can use it directly when you get the kit. No need to pair them again. 4. You can add more remotes.

About Installation (control "-" port of the battery): 1. The thin red wire is connected to the "+" port of the battery, connect the battery connector to the "-" port, and the copper pillar to the negative port of the car. 2.

Q & A: Q: Will this device drain my battery? A: This switch is 5mA only, and the car battery can power the switch for 3 years even if you don't start the engine.

Q: Will it delete car's data if I turn off the power? A: It is possible, but not for all cars. Better ask your car company first.

Q: Can I pair more remotes with the switch? A: Yes. Assume you have a new remote with button A (or ON) and B (or OFF). Press and hold the "SET" button for one second, and the LED will turn on. Then press and hold remote button A (=ON), and the LED will blink 3 times. Next, press button B (=OFF), and the LED will blink 3 times again. The toggle mode is now completed (Press A or "ON" to switch on; press B or "OFF" to switch off).
