yes flat-top's.
vtc5 > vtc4 > samsung inr 25r > lg he2, i would get 4-6 batteries if you using sigelei 150w... i chain vape... 2 batteries last me less than half a day... dunno how people use it for three days... lol
flat tops > button tops unless your mod can fit button tops
vp2 > vp4, get two vp2 or 1 vp4
I've yet to see a flat top battery have vent holes.
Are there any other batteries around with higher capacity that would work here?
My sony, mnke, and MXJOs that are flat top batteries have vent holes...I'm confused...
