100pcs 2X Cell/3xCell 21700 Battery Holder Bracket Cell Safety Anti Vibration Plastic Brackets for 21700 Batteries (3X21700 Cell)

I have bought a LOT of these… I Make battery packs. They make it easy! Clip together to make the shape you need. Inexpensive & work. Not more I can say !

These do not fit 21700 cells. I bought a few packs of another brand but they ran out so i got this one instead. The cell will not fit at all, there's like a 2-3mm size difference. The cells I'm using are EVE 50C 21700 cells.

So far have made 10 battery packs with Samsung 40T 21700 cells in a 14s3p arrangement. These fit the batteries nicely. They fit together snugly and the batteries are not tight in the hole.

Product did not fit 21700 cells without breaking... I tried multiple different cell manufacturers to make sure it wasn't just odd sized cells

Mold is too small for my 21700's. The cells break the molds when forced in.
