Lithium 18650 stacked no solder battery pack

thingiverse

This is a no-solder lithium ion battery pack frame. Simply slip in a length of 12-gauge wire into the built-in groove. In Version B and C, nickel tape (recommended) can be used instead. Stranded wire is preferred over solid wire because it compresses slightly, ensuring better contact. Various pack designs are available, including 1s20p, 2s10p, 1s16p, and 2s8p configurations. The source file for 123d design has been uploaded, allowing users to edit the design by downloading 123d from the internet archives. Printed at 50% fill with optimal settings, ABS plastic was used with a 230-degree tip temperature and 90-degree plate temperature. After printing, simply lay in the wire or nickel tape and snap in the batteries! Don't forget to install a Battery Management System (BMS). The tolerances on this design are tight, so use electrical tape on the edges or scale it down for a snug fit. To ensure accurate scaling, print at 99% scale. Begin by printing the twin stack first, as printer variability can affect scaling. Update: slots have been added to accommodate nickel tape. No supports are required. Print at 100%. Update: testing or solder holes have been added, which also enhances structural strength. No supports are needed for this version either. Print at 100% for Version C.
