Far from it. If you're lucky, the 18650s will be re-badged recycled cells form failed laptop battery packs (usually one cell is completely dead but the rest still have a little life in them). If you're not so lucky, it's from a back-alley micro-factory with no quality control and the cells can literally burst into flame (which has been the big issue with "hover boards" recently).
