My wire good enough for 2nd Batt?

[Hoppinlowrider 10+ year member]

I got KnuKoncepts 4 guage wiring (capable up to 120A) running to my amp. I got a lot of dimming so i want to add a yellowtop in the trunk. I have a 98 Lumina n my alt is rated at 105A. I tested in once n its capable of about 115A. I did the big 3 in that same 4 guage. I want to know if that wire would be good enough to recharge a 2nd battery in my trunk.
