Interesting: the dimensions of the Boxer 133 watt are listed as the same as the Boxer SX350J.
I'm leaning towards getting this dual 18650 version because of that smaller size and the better battery life of dual 18650s, plus I always have the option of using my Opus if I need more than 133 watts. I really would like to get a white one, but I'm not sure how that would hold up.
I'm really bothered by the fact that there is a 50 dollar difference right now between the LiPo version and the 18650 version. Do some battery contacts, a plastic sled, etc really cost another 25 dollars? I know nothing about these kinds of things which is why I am asking.
