No, caps are not batteries, they behave very differently. There is no absorption phase or concept of trickle charging, so no CV needed, you just shut off the charge when they hit 8.1v.? Shouldn't be there a CV as well ?
Use two ounce copper not one ounce. Some places have 3 or 4 ounce copper.If current is a problem

It's not - using the calculations in the datasheets for most buck converters - because those calculations are for CV output as, for most applications, that's the norm. They are useful for setting the basic components, but then you're on your own. Ths is where you need to do a lot of researching parallel ideas.How is the duty cycle related to the current in the buck-converter, i mean i don't see it being used in any equations for inductance or for calculating max current.
