Any of the batteries and clearomizers suggested in this thread so far will work for you. You just need to decide on functions, form factor and price.
Don't forget to buy replacement heads (the heating coil assembly) for whatever clearomizer(s) you chose. The heads do go bad over time so you might as well order some with your unit. Some kits include a few extra heads.
