The 133w limit is set by Evolv when using their DNA 200 chip with two 18650s (or a 2s lipo). It's not a definite limit for dual 18650s in general. Having said that, most of the good
batteries we use are rated for max 20 amps and I wouldn't push a dual battery mod using those over 120w (so not even 133w). With 30 amp
batteries you could go to 170w or so without exceeding the amp limit. In my opinion there's no safe way to get 200w with two 18650s.
