As the title says, I am having trouble finding a barebones box mod that is made for 2 18650s in parallel and a dna 30 chip. I'm sure there's some bulky box mod out there that can do it and I also looked at the ipv3. But I want something not much bigger than the hana modz v3 I have now or kind of like the hana modz V4d. It doesn't last long enough as is and I want to build it the way I want it. If anyone has links to what I'm looking for, I would appreciate it.
