no you dont need either unless your pushing a huge amount of power. I would reccomend an Optima yellow top, just for good measure. They can die and die and die again and still take a charge, now my red top is a piece of junk, I've had it replaced under warrenty twice and it's dead again without taking a charge... stick with the yellow.
