The file 'Modular 18650 Li-Ion Battery System (Hexagon) 3D Printer Model' is (STL,stl) file type, size is 4.9MB.
This is a hexagon battery system, the idea is to be able to build a battery made up from 18650 cells to almost any shape you want using the modular connectors. You would still need to either spot-weld connection tabs to the batteries or use another mechanical means of connection.
