Choosing an enclosure starts with the exact model. A cell-format label and a polished image do not answer every buying question.
Our buying guides cover the information to request before ordering: approved cell models, included parts, electrical ratings, product instructions, and the terms for your destination. The current 21700 DIY kit is listed at US$69. Cells are excluded and soldering is required; online checkout is not available yet.
