About this 3D model

This battery case is built specifically for 33140 LiFePO4 C33 cells, offering a clean, secure, and highly practical solution for assembling both 4S and 8S battery packs. Whether you're building a compact power module or a larger energy storage setup, this design focuses on durability, organization, and ease of assembly. The case features precision-fit battery holders in two configurations: 1x4 layout – ideal for compact 4S packs 2x8 layout – perfect for larger 8S configurations or modular expansion Each holder includes rounded edges, reducing stress on cell wrapping and improving overall safety during installation and long-term use. The smooth contours also make handling easier and give the design a more refined, professional look. ** The cover is tight fit. Tested with Bambu Lab P1S. Use 4 pieces M3 x 5mm screw to secure the cover or, use a bit of superglue to secure permanently ** Features: - Designed for 33140 LiFePO4 (C33) cells - Supports 4S and 8S configurations - Includes 1x4 and 2x8 battery holder layouts - Rounded edge design for safer cell placement and reduced insulation damage - Tight, secure fit to minimize movement and vibration - Modular-friendly structure for flexible pack design - Clean spacing for wiring, nickel strips, or busbars - Supports 25A Mini BMS.
