Ive seen this question pop up a lot on Reddit: “Are these new batteries safe?” At least some people have the brains to ask…
There are 4 main Li batt research groups/manufacturers, for our use: Sony, LG, Panasonic, and Samsung.
Any battery that makes claims outside the specs that these folks set are lying. Vappower has a cell they claim is 35a continuous with 50a pulse NONE of the 4 main batt manufacturers produce anything like this so it leaves two possibilities, they are lying and using lesser cells (bin b) from one of the big 4 or they have somehow spent millions in R&D then produced these cells without anyone else in the world knowing. In other words they are lying.
Any batt that claims high end specs are made by one of the big 4, they are called “bin b” cells meaning they didnt meet the manufacturer specs so they are sold to other companies to be rewrapped. Efest, Vappower, MXJO, etc all sell bin b sells made by one of the big 4.
With all this said please just purchase your cells with the proper wrap, and from a reputable reseller, so you know that it is the best quality. And if i am incorrect about any of this information i would appreciate someone inform me, i do not like to spread false information. This is information i have learned over the last few years.
Stay safe, vape smart!
