TAINECTC Battery Kill Switch for Car — 12V/24V, 140A, LED Display

Smart Remote Control for Parked Vehicles

TAINECTC’s Battery Kill Switch gives you smart, at-a-glance power control for your vehicle. The compact unit features an LED voltage display and a reliable latching relay, delivering remote control with ultra-low standby consumption. It’s designed to simplify power management without sacrificing accessibility or visibility.

The kit is built for everyday practicality: a concealed switch, a clear voltage readout, and a robust control system that helps you manage power with confidence. The result is a discreet, user-friendly solution that fits neatly into a crowded engine bay or under-dash area, so you can keep focus on the road ahead.

Protect Battery Life and Reduce Drain

The Battery Kill Switch includes intelligent protection that monitors battery voltage and charging conditions. When voltage falls below 11.8V or remains in the 17–24V range, it can auto-disconnect after 300 seconds to help prevent deep discharge. When charging voltage reaches 13.6–17V or 27.2–30V, the remote may become temporarily unresponsive to avoid undesired operation while driving, with manual On/Off still accessible for immediate control.

Simple Installation and Flexible Mounting

Designed for negative-terminal connections, the switch is straightforward to install in most vehicles. If a flat mounting position isn’t feasible, transfer shims enable side mounting, and slotted connection tabs allow vertical height adjustment during setup. The result is a tidy, secure fit that works in compact spaces.

Real-World Use and Practical Benefits

• Remote control helps manage battery usage during long parking sessions, reducing worry about parasitic draw.
• LED voltage display provides quick, at-a-glance checks of state of charge before you start the day.
• Auto-disconnect helps protect the battery in classic cars, boats, RVs, trailers, and more.
• Manual On/Off control adds a straightforward fail-safe when required, without relying on remote operation.

Versatility Across Vehicles
