32700 / 32650 lifepo4 4s 4p batttery cell holder
thingiverse
Building my own batteries I have designed this battery holder (work in progress). I have tried to use minimal material usage and keep the print time as short as possible while maintaining strength.With this design I believe I hit these goals. The design has room for 32700 battery cells (I use liitokala Lii-70A cells given their high capacity, discharge current and fire safety), these fit extremely well and snug: <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> and can accomodate up until 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> I'm in the process of designing the spacer in between as well as lids and cable routing items to go through the cells. If you have any good ideas and or suggestions please provide feedback via the comments and I can incorporate them in the final desing.
