Not sure if you have seen these before?
Brise EV200 Battery Isolator
Available on Demon Tweaks. They look like a nice clean option although for a battery isolation kit that you can have two remote push button switches to cut the power rather then the normal 6 pole FIA red switch and remote cable.
I was thinking of buying one but the price is a fair bit!!!
So after some late night research i worked out that these are actually a TE product that has has the name changed to Brise.
The part number for the Tyco Product is Kilovac EV200 Series - EV200hAANA
