Interstate Battery terminals problem

[Uid4iboats]

I am adding a 2nd battery to my boat with a perko switch. The terminals on the switch are 5/16, as well as both pos and neg terminals on the batteries. I cannot find two red 2 gauge cables that have 5/16 lug rings to hook the batteries to the seitch? I dont have the tools to make them myself and am surprised that i cant find them online - which makes me think something is wrong with my setup? Anybody know where i can buy these? Or if Im going fown the wrong path?

Typically people make their own.

But you can get stuff like this if you look around

(3/8 will work fine on a 5/16 stud)

Thanks oldjeep. I did see that but also read in a forum that you should use the right sized rings. If 3/8s are fine to use on a 5/16 terminal then that solves my problem

3/8ths work fine. You need a little larger hole to fit the lug onto the stud anyway.

Welcome to iboats, Uid4.

3/8" is just fine.
