Correction: the batteries being marketed to vapors is shady business, the original and authentic manufacturers have nothing to hide, nor do they use misleading labeling or ratings.
Vaping is such a small part of what these cells are used for, in the case of power tools imagine what would happen to a company like samsung's sales if brands like dewalt, Milwaukee, bosh, makita and others found out the cell they use in their power packs was mislabeled. They have to trust the company that makes the cell they use, as the liability for a customer being injured is now on them and if that company can't back up a cells rating they will find another who can.
In the case of efest or mojo they will just crawl behind the shield of china's legal system where they really can't be touched and brush it off. Then probably start over as another " competition" brand a few months later.
I'm starting to feel like its maybe time someone starts a class action suit against these brands for false and misleading advertising
