Which combination do you currently run?

 

For those of you guys who have more than one battery, are you using an isolater?

 

I am waiting for an upgraded alternator. My car has a limit to what size i can use because of engine design.
I don't like to use isolators as they steal too much power. I do believe in fusing and the "Big 3".
It always comes down to that age old statement, "you'll get as much as your weakest link will handle."
