I continue to find that there is always a more gangster way of building cars. Needed a battery cut off switch, was tired of the big clunky switches that take up so much room, are heavy, and have huge battery cables running to them. So I did my research and found this. The @cartekmotorsport solid state battery isolator. This little solid state relay can kill the power to your whole car as well as the ecu to completely power down your car with the push of a small, easy to locate button. Simple, clean, effective and also FIA approved!
