Efest has a newer 35 amp battery in 18650. I suggest you get a couple of those for sub ohms
I wouldn't dream of trusting efest batteries. they have a long history of overstating their batteries, and in every test I've seen, efest come in near the bottom. Sony vtc4 for me, at least until they release the vtc5
unless I want 490 or 350, then nothing but aw. but I like my mods like I like my women. big and full of energy
