Remote Battery Disconnect Switch 12V 240A, LED Voltmeter

A flat vehicle battery is a frustrating way to start a trip, and in a motorhome or campervan that sits parked for weeks, small drains from alarms, ageing wiring or forgotten lights add up quickly. This 12V remote battery disconnect switch lets you cut the battery off in seconds, protecting it during storage and giving extra peace of mind between trips.

A bright LED display shows battery voltage in real time. Three remote controls let you disconnect or reconnect from up to 100 metres, and a manual switch provides backup control. If the voltage drops below 11.8V, the switch cuts power automatically after 120 seconds to prevent the battery draining. Above 13.5V the remote is disabled and manual operation is required, which helps avoid an accidental shutdown while the engine is running. The switch is rated at 240A with 500A instantaneous current, and standby consumption is only 0.003A.

This isolator suits motorhomes, caravans, cars, boats, trucks, trailers, ATVs, UTVs and motorcycles with engines under 4.0L. The package includes the switch, three keychain remotes, two silver gaskets, a buffer pad and a manual. It is designed for a negative-ground connection. Installation on the battery should be done by a competent person following the manual.
