ZOZOMOTORS 3/8 Side Post Remote Battery Disconnect Switch – 12V Heavy Duty 200A/1000A

Overview

The ZOZOMOTORS 3/8 Side Post Remote Battery Disconnect Switch offers a robust, remote-ready way to manage power for a wide range of 12V applications. It’s built to fit GM side post terminals and other threaded stud or hole terminals, making it suitable for cars, trucks, RVs, ATVs, boats, jet skis, and motorcycles. A practical solution for preventing parasitic drain or adding a theft deterrent, it puts power control at your fingertips without needing to pop the hood.

The system includes a FOB-style remote that works up to about 100 feet, so you can disconnect power quickly from inside the cabin or at a convenient location. The setup is designed for real-world use, with a focus on reliability, ease of installation, and long-term durability.

Why choose this switch

High current capability is matched to everyday reliability. This device provides 200A continuous current with up to 1000A crank amps, giving you strong starting potential in cold weather or when the vehicle needs a quick power cut. The remote receiver draws only a tiny amount of standby current (0.001–0.005A), helping minimize any additional drain while idle.

Electrical flexibility is another strength. The unit runs on 12V and ships with a flexible connection wire (2AWG) and copper bars to simplify wiring even in tight spaces. You can install on the negative side (recommended) or on the positive side if your setup requires it, enabling use across cars, trucks, RVs, ATVs, boats, jet skis, motorcycles, and other 12V systems.
