A box mod is the least expensive way to get long battery life. You can buy one ready-made or BIY. I use standard or long 510 batteries at work as they are slim and fit my pocket for ready access, and a box mod at home for the pure pleasure of long battery life with longer-lasting voltage before dropping off.
The least expensive and most natural upgrade from the 510 is the eGo/Riva type battery. It's a bit fatter and lasts, depending on the capacity, from 6-8 hours to a day or two. The smallest ones are 650 mAh, the largest--1100 mAh.
