Will you ever make one with a rechargeable or replaceable battery?

Yes we will but not for this model , as we want to keep it small and lightweight as possible. Adding room for handling battery replacement or charger , will add to the size and weight . However, with current battery lifetime being few years with proper use, (can even get to 8 years) adding size and weight for such a rare task , seems unnecessary.
