18650 Cell Holders
Here are square cell holders. Just 3 cents per cell hole. These fit 18650 cells perfect. Save space with these hexagon holders, no more wasted diamond space in between cells using the standard square shaped holders. Yes they snap into each other too so you can make, for example, a 5x10 50 cell holder using 5 of the 1x10 holders and they will snap into each other.
If you select 1x10 that means you will get a 10 cell holder like you see at the bottom of the photo.
