12x 18650 12v Battery Pack

thingiverse

Large case to hold 12x 18650 battery cells. with 4 rows of 3 cells in series. Produces a 12v 10.4 Ah battery.( ah is average depending on cell quality) or 124.8 watt. i am using it to power a 100w LED chip and make an insane hand held torch. however the battery can be used for any 12v use case. Instructions to make the battery connections I used some small screws with some springs over them. the screws go straight through the cap for copper wire (i use 15amp) to be wrapped on the other side than the cover plate over that to clean things up. please refer to pictures for more clarity. the bottom wire is passed up through the center of the battery pack, the the top wire just goes through the cover. you decide which it + and - the caps are held on with small screws the covers with glue. Printing The caps should be printed solid the rest can be printed however you think best. Any questions or if something is unclear please comment
