I have owned a SmokTech vv Gripper for a little over 2 months. As it is well known IMR 18650 batteries are required to get the battery door closed all the way. Well, I just bought some Panasonic CGR18650CH batteries for a good price on Ebay 2X New Panasonic CGR18650CH CGR18650 3 6V 2200mAh Li ion Battery One Free Box | eBay from China. The battery door will close, ALL THE WAY, with no gap with these batteries. These are the only battery I can seem to get the battery door all the way closed with. They have been proving to be good batteries with a LONG life as well.
