Hello everyone! I am having trouble finding information that is new for making a decision for batteries. My setup is a Joyetech eVic-VTC mini (updated to run at 75w to 600° F on ni, ti, and ss) running a YouD Zephyrus tank with .15 ohm ni200 coils. What would be a good battery choice that would be safe for running this combination? I'm also wanting it no not go dead after only a few hours too but if I have to sacrifice that for safety then I wont think twice about it. I typically vape around 420° F at 50w locked in at .15 ohms. I want something that will handle me occasionally cranking it up to blow some massive clouds too but typically I keep it around the stated numbers. Thanks in advance for the advice!
