So Im looking at putting a optima yellow top battery CCA750 CA870. I am wondering if the chargeing system will actually keep this much larger battery charged or will I have to put a battery charger on it time to time or should I just go a bit smaller. Yes I know its gonna weigh like 43#s haha. This I dont care about I do not race its muddin for me. But I have a 1200watt amp for speakers and plan on putting light bars later.
