Ok so here's the deal. I have a custom Hana style dna 40 device but I want something with dual batteries or even can be Lipo as long as it's longer battery life than a single 18650. I just want to see if there's any mods out there that I don't know about yet. I already know about the vaporshark Vaporflask and Hana v4d and a bunch of dna 200 mods and mainly all the 200 mods I'm seeing has pretty bad battery life so not sure if I might be missing some mods. I can afford about $250 on a mod right now because I just sold some stuff on eBay So any suggestions will help
