Lithium 18650 stacked no solder battery pack

thingiverse

This is a no-solder lithium ion battery pack frame. just need a length of 12gauge wire that you put in the built in groove. In Version B and C, you can use nickel tape (recomended) I think stranded wire is better than solid, it will compress a little and give better contact. various pack designs available, 1s20p, 2s10p, 1s16p, 2s8p, etc.. I have uploaded the 123d source file, so if you want to edit, download 123d design from the internet archives. I Printed at 50% fill, best settings. I use ABS,230 tip temp, 90 plate temp. Just print, lay in the wire or nickel tape and snap in the batteries!! Don't forget to use a Battery management system (BMS)! Tolerances are tight on this one, use electrical tape on the edges, or scale it down to get a tight fit. Print at 99% scale print the twin stack first to get the scaling right, varies by printer Update: Added slots for nickel tape! No Supports Needed! Print at 100% version B Update: Added testing or solder holes! also improves structural strength! No supports needed! Print at 100% version C
