Help with batteries!!!

I have a batcap 800 and an optima yellowtop. I have been thinking that I will sell my yellowtop and go all batcap. would a batcap 800 in front and a batcap 2000 in back work well for a 2500wrms system? I will have a 2500d orion amp powering an fi btl 15. I also have a 180 amp alt.

I also have in mind selling all batteries and getting kinetic 2400 for back and kinetik 800 for front. Any ideas??
