Have you tried starting the car with this setup yet? I haven't seen a circuit breaker used in the starter power circuit before. The 150 Amp rating seems low -- especially if it's cold and you have to move thick oil.

150A works fine for my setup with the Miata battery, started the car about 5 times in the spam of 4 hrs on Saturday with some driving in between, temp was in the teens that night and I run 10w40 oil.

like he said 150A was fine.

I have started it on multiple occasions already including a few times after the car sat in ~10 deg chicago temps.

Started without even a hiccup

Ahh, I vented my Miata battery

I drilled a hole behind the bin, inserted a grommet and run that red silicone hose out by the rear subframe. The rubber hoses are some tight angle pre-bent hose I have laying around from my MX-6, so they are not pinch against the bin.

I'll get a pic for you. Right now, it's just sitting in the drivers bin and not fully mounted as I was doing testing on my setup. It's light enough that I may not worry about putting it in the passenger bin because I love having access to and empty passenger bin from the drivers seat.
