One Battery or Two. 12V or 16V

What do you have and why?

The Wagon has two 16v. I feel like the MSD 7AL fix needs a full 13.5 Volts. I feel that the higher energy spark creates a smaller chance of blowing the lid off the intake. Two batteries helps in final rounds when you get hot lapped. A Second battery is worth .04 when removed. I put it on the charger when I leave for a pass, that way I can swap it out if not enough time to get a good charge.
