First off, what do you guys prefer? Circuit breakers vs fuses? And what size fuze/circuit breaker should I run between my under hood battery and the battery I the trunk? I'm running 0 ga wiring on a 180 amp alt. with 2500 rms

I prefer fuses.

Fuse to the wire capacity. If ofc then 300amp should be fine.

Use a 300 amp ANL fuse. I hear circuit breakers get weaker every time they pop.

Awesome, I appreciate it guys! Also do you ever have to charge a battery with an amg charger if you store it and it stays above 12.6v? Or if it's above 12.6 I can just throw it in the car and bump? I pulled the battery for the winter, the car is in storage
