Take full control of your vehicle’s power — without ever popping the bonnet
Tired of returning to your car after a few weeks only to find a dead battery? Or perhaps you want a reliable anti-theft solution without the high cost of a complex alarm system? This remote-controlled battery isolator switch solves both problems with one simple installation. Designed for 12V systems, it handles a 200A continuous current and is compatible with everything from standard cars to boats and solar power setups.
Important: To prevent damage to the circuit board, this relay must be installed on the negative terminal of the battery.
Why choose this isolator switch? (Key Benefits):
- Instant remote disconnection — Isolate your battery at the touch of a button, without needing to access the engine bay.
- Effective anti-drain protection — Ideal for vehicles left standing for long periods, such as seasonal cars, campervans, or winter storage.

Frequently Asked Questions
Which battery terminal should I connect this to?
It must be installed on the negative terminal. Installing it on the positive terminal can cause permanent damage to the internal circuit board.
Is it compatible with diesel, LPG, or hybrid vehicles?
Yes. It works with any vehicle using a 12V battery, regardless of whether it is petrol, diesel, LPG, or a mild hybrid.
Will disconnecting the battery reset my onboard computer?
It is possible. Some vehicles may lose radio presets, clock settings, or comfort preferences when the power is completely cut. Please check your vehicle’s manual if you intend to use the isolation feature frequently.
Can I use this on a boat or solar system?
Absolutely. It is specifically designed for marine environments, campervans, and portable solar installations that operate on 12V.
