A second battery would help, but with that amount of power I think you should be looking into a high output alternator.

Yellow top arnt that good. In the battery tests they come in like last place lol... Look into deka agm,Duracell agm, energizer agm , Juicebox... When u start talking Xs power and north star that's $$$$$$$$$... But really as said above ^ a HO alt is needed to run 2500watts. Excessive power or Ohio gen only companies that would get my money$$
