Ok I just found out that there is an extension cap for using the 18650 batteries on the provari mini. Where can I find one and which is most preferred ? I am in the United States and would like to buy here but will have it shipped if I have to go that route. Thanks for any intel you may have.
Also what batteries are yielding the best results on the provari?
