I based my comment of your batteries sucking on 2 things.
1. They were 18650
2. You said Efest.
Efest are known for rewrapping batteries and grossly over rating them.

I need to update the pic I've been posting.Was just about to post it lol xD
Taking one hit from it changes it more than that.Forgot to tell one of the reasons increasing my ohm reading that I noticed my dna200 mod reading are always above the yihi by 0.02 to 0.03 ohm
Samsung 25r, LG hg2 or hb6, or Sony vtc4 or vtc5 are all good batteries. I use either 25r's or hg2's myselfYihi and dna200. Thanks for the battery tip. There are many models available from the mentioned batteries. What are the recommended MAH and A?
