This remote battery disconnect switch gives you full control over your vehicle’s power without opening the hood. It prevents silent battery drain and protects your electrical system from unnecessary wear.

Control your vehicle’s power and avoid unexpected battery drain

✅ Prevent battery drain during long parking so your vehicle starts reliably

✅ Cut off power remotely without opening the hood or touching wiring

✅ Protect battery life by stopping drain from lights and electronics

✅ Handle high loads with 240A rated current and 500A peak capacity

✅ Save energy with ultra-low 0.003A standby consumption

✅ Automatic shutoff below 11.8V prevents deep battery discharge

The switch installs on the negative terminal and controls power flow using a magnetic latching relay. Once connected, you can shut off or restore power using the remote when voltage is within 11.8V–13.2V. If voltage drops too low, the system automatically cuts off after 120 seconds to protect your battery.

This is ideal for cars, trucks, RVs, boats, ATVs, and trailers that sit unused for days or weeks. It prevents slow drains caused by electronics, aging wiring, or forgetting to turn off lights. You keep your battery ready without constant maintenance.

Unlike basic manual switches, this system adds remote access and automatic protection logic. It reduces the need to open the hood, avoids unnecessary drain, and adds a layer of control that fits real daily use.
