Keep Your Battery Safe & Extend Its Life – 240A Battery Disconnect Switch with Smart Voltage Protection
Tired of a dead car battery after long parking? Our 240A Battery Disconnect Switch automatically cuts off power when voltage drops below 11.8V, preventing parasitic drain from electronics, aging wiring, or forgotten lights. When the voltage rises above 13.2V (engine running), the remote is disabled to avoid accidental shutdown while driving.
Why Choose Our Battery Kill Switch?
Smart Voltage Protection – Auto-cutoff at 11.8V saves battery; 13.2V+ lockout prevents driving interruptions.
Ultra-Low 3mA Standby Current – Uses a mechanical magnetic switch to minimize power loss.
Heavy-Duty 240A Rated Current – Handles high-power systems (500A instantaneous surge).
Prevents Battery Drain – Stops hidden power loss from alarms, GPS, or faulty circuits.
Easy Negative Terminal Installation – No complex wiring; just connect to the battery's negative terminal.
Perfect For:
Long-Term Vehicle Storage (RVs, boats, classic cars)
Preventing Theft – Disables power remotely (remote-controlled models available).
Off-Road & Marine Use – Durable design resists vibration & moisture.
Installation Tip: Always disconnect the battery before installation for safety.
