18650 / 21700 Stackable cells holder

10 Cells holder that are stackable with banana jack connections

 

Easy to build, you only need 12x12mm AA Battery terminals, 4mm banana jack (the cheaper one) and 3mm x +/-15mm length screws.

Slide each terminals into the base, solder a wire between each (I used solid core old telephone wire)

 

There's 2 versions, one for 21700 (this one can accomodate 18650 if your terminal springs are long enough). and a 18650.
