What is the best battery for me? I don't go over 15 watts with any of my RTA's
Any of the batteries below in bold will be good for you. AW has updated their batteries with more mah and amps, which are always a safe bet as long as you buy from a reputable dealer like RTD Vapor, Illumination Supply, Orbtronics, or Lighthound. Beware of fake AW batteries on the market which may be old/used or inferior quality batteries that are re-wrapped to look like genuine AW.
