Battery relocation fuse

Right I have a 2005 fabia vrs asz. I have ran auto leads 0awg wire to the boot but as I have ran 0awg I was thinking I might as well relocate the battery while I'm at it. I am wondering how much amp draw will the fabia draw fro cold like at -5 I am putting circuit breakers in so it will trip out but I was wondering what amp circuit breakers to use. I am putting a circuit breaker in the front and one in the back as I don't want anything setting on fire if the 0awg even shorts to ground. By putting in 2 circuit breakers I will save the battery and the alternator. I know some people don't run a fuse or circuit breakers and I'm not a big fan because if it shorts it could blow the battery or even catch fire so I rather run a fuse

Also i not sure what 0awg can support at 5m or 16 feet long

Any one know on here ?
