i only recently began to realize the difference good batteries make- especially with sub-ohm builds, i wouldn't take that chance, I make sure anything under 0.5ohms is powered by an MNKE, SONY, or ORBTRONIC....above- standard AW 2000, also AW 18350's, AW 14500's..while you do have a point, this is not CPF.
not all packs are created equal,
2300mAh 18650... i highly doubt its high drain...
And not all ECF users are competent enough to disassemble a battery pack.
And of all places the Newbie forum is not the place for this kind of information.
Just the other day, a user wanted to take off the shrink wrap on a battery, just because it looked cooler on his DIY mod... see my concern.
i know a good bit of battery info, and do have machines to test batteries, but even I wouldn't take the risk on a used laptop pack.
I've owned 10 AW's in the 3 years that i've been vaping... They have paid for themselves. no need to pinch pennies in that department.
I'me just advocating safety here, Vapers shouldn't be missing teeth, due to an oversight.
they are BETTER! i know from using all kinds of batteries- there is a HUGE difference in performance and reliability! The battery is our FIRST safety priority IMHO!
