Make sure you buy VTC4 or any Sony from a reputable dealer. I don't have any 26650 mods but AW makes good batteries. RTD Vapor is a good source. Also I wouldn't worry about 100 watts on that T6 my friend. That mod is lucky to push 60 watts at the most. Cloupor lied about the voltage, amps, update etc. That box is supposed to be able to do 20 amps when in fact it can really only handle about 13 amps. The search button is your friend here. There are several videos of people who have tested this mod and can attest to what it will or wont do. Also the Cloupor Mini's have issues right now where the boards are melting or the mod is catching fire. Cloupor also has horrible customer service as well and a lot of people are staying away from them because of the T6, T8 not being advertised correctly, T5 firmware crash, and the new Mini problems. My best advice to you would be to ebay that mod perhaps and get a more reliable brand like IPV, or Sigelei if you are looking at 100w mods. I do like the the way the Cloupor looks however. It is sleek and has a nice appearance don't get me wrong but I am scared of anything they put out. Just do your research and vape safe
