Robust connectable high current cell holder

This is an evolution from my other robust cell holder: https://makerworld.com/en/models/2355110-robust-high-current-cylindrical-cell-holder

Along with the goals in original design, this also make it possible to connect multiple cell holder together for balancing or connect in serial to raise voltage.

The hardware you need for this is minimal, you only need 2 nickel strips of 7 or 8mm width cut to length for 3D printed screw version. For normal HW screw version, you'll also need 2 M3 nuts and 2 M3 bolts.

To assemble, put your Nickel strip into the terminal plate, then bend it to the side that have a pimple (not the side with hole), then bend it once more and put it through the hole of the holder. Now, put your M3 nuts to the captive nuts hole on top of the holder and screw your M3 screw in. Repeat for the other side.

Now, after you put your battery cell in the holder, use a screw driver to tighten one of the screws to make good contact with the cell and loosen it when you want to remove. When tighten, screw will push directly into the part of nickel strip you inserted, so you can tighten it without worrying about breaking fragile plastic parts.
