Dual 18650 Battery Holder

thingiverse

Battery holder for 2 18650s in Parallel and 5V Micro USB 1A 18650 Lithium Battery Charging Board. Designed to mount on a surface with a screw and be somewhat weather resistant. Pictures show 1st print that had warping and shrinkage issues as well as being too tight. It has been updated too be thicker on the outside and looser fitting. My understanding is safe to charge and 18650s in parallel if they have always been used in that way since new. Mine came from a laptop battery pack and were that way already. There are many hits on ebay for the board, The link I had for it is not longer good but search and you should be find it. Print Settings Printer: Flash Forge Creator Pro Rafts: No Supports: Yes Resolution: .2mm Infill: 100% Notes: Use Glue gun for 3d printing pen to secure charging board in place. 1s version that is shown in the pictures was way to tight of a fit, and has been adjusted for a looser fit, and will need to fixed in place with glue gun for 3d printing pen. if you want to be able to take it back apart perhaps drilling a small hole right below were the inside and fits and inserting a peg.
