Cylindrical Battery Holder v0.0.3

thingiverse

This is a battery holder engineered to use the Keystone 209 battery spring clip, thus eliminating the need for any soldering or welding of tabs to cells and making it easy to replace cells in case of failures. The Keystone 209 battery spring clip can be obtained inexpensively from numerous online electronics warehouses such as Digikey, Jameco, Mouser, and other suppliers. It is currently designed for use with 32650 sized cells (LiFePo4 cylindrical cells), but should easily adapt to any cylindrical cell type including 18650, D, C, AA, etc. Given the relative rarity of 32650 sized cells, I was unable to find any premade cell holders for them. The holder secures the battery cell firmly due to spring tension, although it does not positively latch the battery in place. This feature will be added as a separate version.
