ZOZOMOTORS 12V Side-Post Remote Battery Disconnect Switch — 200A Continuous / 1000A Crank, Includes 2 Remotes

ZOZOMOTORS side-post remote battery disconnect is a heavy-duty 12V on/off kill switch that lets you cut battery power from your vehicle with a key-fob press.

This compact, high-current solid-state relay fits GM-style side post and other threaded stud battery terminals to stop parasitic drain, protect batteries during storage, or act as a theft deterrent without needing to open the hood. The receiver is built into the relay and comes preprogrammed with two key fob remotes, so installation and first use are straightforward. Rated for 200A continuous current and 1000A crank, the unit handles starting loads and repeated cycles better than standard relay switches.

How does the remote battery disconnect prevent parasitic drain?

When you switch the device to OFF with the included remote, the relay severs the battery connection to the vehicle’s negative circuit, isolating accessories and modules that draw current while parked. This stops small continuous draws from electronics that otherwise reduce battery life over time.

• Solid-state relay eliminates mechanical wear and provides long service life.
• Receiver current draw is minimal (about 0.001–0.005 A) while connected.
• Remote-controlled OFF removes power to prevent slow discharge during storage.
• Preprogrammed key fobs work out of the box—no extra coding required.

Will this switch handle engine starting and cold cranking?

Yes — the switch is specified for 200 amps continuous use and can deliver up to 1000 amps of crank current, which is enough to support typical cold starts for most cars and light trucks. The heavy-duty design and quality components help it endure high current spikes during ignition.

• 200A continuous rating for sustained electrical loads.
• 1000A crank capacity to deliver necessary starting surge.
• Robust construction reduces the risk of failure under load.
• Suitable for repeated start-stop demands of daily use.

How easy is installation and what hardware comes with the kit?

The kit includes everything needed for a straightforward install: the relay with built-in receiver and wire harness, two remotes, a side-post adapter, 2 AWG connection wire, copper connection bars, mounting screws and a 3/8"-16 bolt. A wiring diagram and step-by-step instructions are supplied to guide either a DIY mechanic or a professional installer.

• Includes 2 remotes and pre-wired relay receiver for quick setup.
• 2AWG connection wire and copper bars simplify tight-space installs.
• Recommended mounting on the battery negative side (positive also allowed).
• Wiring diagram and instructions included to reduce installation errors.

What should I know before using the disconnect switch?

Because the device cuts battery power at the source, electronics that retain presets or memory (radio stations, ECU learned features) will lose their stored settings when the switch is off. Also, some jurisdictions require the battery to remain connected for emissions checks, so follow local regulations before disabling power.

• Disconnecting removes stored settings in radios and similar electronics.
• California: keep battery connected for several days before smog tests.
• Use recommended wire routing and secure mounting to avoid vibration issues.
• Designed for cars, trucks, RVs, ATVs, boats, motorcycles, and more.

Who is this for: ZOZOMOTORS’ remote side-post battery disconnect is designed for vehicle owners and fleet managers who need a durable, easy-to-use solution for preventing battery drain, protecting parked or stored vehicles, or adding a simple theft-deterrent. It’s a good fit for anyone with GM-style side post terminals or other threaded-stud battery setups who wants a high-current, low-maintenance kill switch that’s ready to install right away.
