According to the Kickstarter page the light comes with an optional separate battery pack using a DC5521 connector. So you can get just the light and add your own 18650 (or 26650) based lithium battery pack. Not quite as clean a package as lights that include the batteries, but I prefer it to designs with sealed cases where I can't replace the cells when they wear out.
