About this item

  • Save battery: This kill switch prevents battery drain from long-term parking, aging wires, and forgotten lights, maximizing battery power storage and extending its lifespan.
  • Smart Protection: When voltage drops below 11.8V, the switch automatically cuts off power after 120 seconds to conserve energy. If voltage exceeds 13.2V, remote control is disabled to prevent accidental shutdown while driving, allowing manual control only.
  • LED Voltage Display and Remote Control: This kill switch features an LED voltage display for real-time battery monitoring and can be controlled from up to 100 meters away via remote.
  • Adjustable Mounting Options: The switch uses a negative link method. Before installation, check for a suitable mounting position in the engine compartment. If incompatible, you can replace the connector to adjust the mounting position.
  • Wide Application: This kill switch is suitable for most 12V vehicles, including cars, boats, RVs, trailers, trucks, ATVs, UTVs, and motorcycles, with a rated battery current below 240A. Negative pole sizes: 9-13 mm and 15-17 mm; not compatible with small post vehicles.
