32700 / 32650 lifepo4 4s 4p batttery cell holder
thingiverse
Building my own batteries has led me to design this battery holder, currently a work in progress. By using minimal material, I've managed to keep print times short while maintaining strength. With this design, I believe I have achieved these goals. The design accommodates 32700 battery cells (I use Liitokala Lii-70A cells due to their high capacity, discharge current and fire safety), which fit extremely well and snugly: <a href="https://s.click.aliexpress.com/e/_d6nz8Vx">AliExpress.com Product - 2020 new LiitoKala Lii-70A 32700 3.2v 7000mAh lifepo4 rechargeable battery cell 5C discharge battery for Backup Power flashlight</a> Additionally, the design can accommodate up to 8mm nickel strips: <a href="https://s.click.aliexpress.com/e/_dWG8xjb">AliExpress.com Product - 10M 8mm x 0.1/0.12/0.15 Pure Nickel Strip Tape For Li 18650 Battery Spot Welding Compatible For Spot Welder Machine</a> Currently, I'm working on designing the spacer between cells as well as lids and cable routing items to pass through the cells. If you have any good ideas or suggestions, please provide feedback via comments, which I can incorporate into the final design.
