Mounting circuit breaker on aux battery

Im currently running a dual battery set up ony 3rd gen. I have the 2nd battery mounted in front of the firewall on the passengers side. I want to mount 2 circuit breakers by the battery.

How are you mounting circuit breakers? Pics would be great also.

Ive added a pic of my 2nd battery set up.

 

Maybe time to go to a Aftermarket distribution block of your liking .

It comes down to what the breakers are for .

It comes down to what works the best for you

 

Im using one 150amp circuit breaker for my amps. I think i may just use another mrbf instead of another circuit breaker to try to clean up all the wiring.
