240A Remote Battery Disconnect Switch with Voltmeter – 12V/24V
Remotely control and monitor your vehicle’s battery with the DaierTek 240A Battery Disconnect Switch. Designed for 12V and 24V systems, it features a built-in voltmeter, low-voltage protection, automatic power cut-off, and manual override for added convenience and battery protection.
Key Features
240A Heavy-Duty Battery Disconnect
Designed to handle up to 240A, providing reliable battery isolation for automotive, marine, RV, and other high-current applications.
Remote ON/OFF Control
Control the battery disconnect remotely without accessing the battery directly. The system also includes a manual control button for local operation.
12V / 24V Automatic Recognition
Compatible with both 12V and 24V electrical systems. The internal control system detects the connected system voltage and operates accordingly.
Built-In Voltmeter
The integrated voltage display lets you monitor battery voltage without needing a separate tester. The display normally remains off to reduce unnecessary power consumption and can be activated with the remote.
Low-Voltage Protection
The system monitors battery voltage and provides different voltage status indicators. When the battery voltage becomes too low, an audible warning is triggered and the system can automatically disconnect power to help prevent excessive battery discharge.
Smart Safety Protection
When voltage is outside the specified operating range, the remote OFF function can be temporarily disabled to reduce the risk of accidental power interruption during starting or driving. The manual switch remains available for emergency shutdown.
