What to chose?? 16v Battery

[Devils speedshop]

Hey

Can someone help me to chose a 16v battery for my racecar:

I been looking at this battery from kinetik, I think it cool that there is 12v and 16v in the same battery so you don't need the step down modul if you have some instrument the can only take 12v. But the weight is a minus..

Also this from PowerMaster S-1000 a light weight battery

I don't want a small battery that can just start the car a few times..

I have the 16v alternator from Shawn Geers on the car.

Hope someone can help me.
