We don't have any Crafty or Mighty in our workshop because the factory has been backordered for a year. Stortz and Bickel has been impossible to reach lately! Someone asked how to replace the battery so we took a look to see what's the deal. It's pretty clear.... the battery is not replaceable in either vaporizer.
Mighty: This youtuber shows how to take it apart (voiding the warranty for sure) and replace the 2 18650 batteries inside. https://www.youtube.com/watch?v=QwKIJDPClAg
Crafty: Contains 1 18650 battery. We say don't try changing the battery, but if you'd like to see inside the vaporizer, check out this video https://www.youtube.com/watch?v=CXTBxBrh2AA
Replacing the batteries in either of these models seems dangerous. Please beware that an improperly installed battery could explode, causing bodily harm.
