Hey guys, I'm planning on adding a second battery once I do the 145 amp alternator upgrade, and I don't want to get an isolater.

Basically I want to run my starter battery and a new auxiliary battery both to a distribution block and then from there, use the outputs for all my stuff.

I want to put switches in both the wires running from my batteries to the PDB so I can choose what battery I want powering what and if I want my auxiliary battery being charged.

So my problem is I am not sure what switches can be used in 1/0 (1 Ott) gauge wire to disable/enable a battery being charged.

Been Google'ing a lot and that's not getting me anywhere.

If anyone has any ideas on what to do or where I can find some high current switches, that'd be great.

 

only thing I can think of would be a breaker
