hey guys does this look like a good relay to have in order to have two batteries in my car? Cheers. http://www.bepautomotive.com/showproduct.cfm?productid=1023
hmmmmm.... looks interesting, I understand the premise behind it, but to complex and too much to go wrong...besides, its only good for 90 amps. exceed the contact ratings at lenght and the thing could fail. I strongly suggest this http://www.amazon.com/PACIFIC-ACC-CORP-Battery-Isolator/dp/B00162EIM2
they come in 200 amp models aswell. and i can buy them in NZ. not gunna buy something from some american site.
And we were to know you are from nz how? You wanted an opinion I gave you one. And "some American site" was just show you an example.....
