DNA250C Dual 26650 Mod

thingiverse

This is a straightforward design for a DNA250C chip that can run on two 26650 batteries. After an exhaustive search turned up nothing suitable, I decided to take matters into my own hands. To assemble this design, you'll need three M2 screws with corresponding nuts and spacers, along with four battery poles and some silicone cable. The lid is secured by eight neodymium magnets. The holes for the magnets measure 4.2mm x 5.2mm and 4.2mm x 2.2mm. This design serves as a prototype, so I haven't had the chance to test it with a DNA250C yet. However, according to the specifications, the batteries should fit perfectly.
