3S 18650 Liion Case

thingiverse

Users can quickly create a protective enclosure for three 18650 lithium-ion batteries. The two-part design is held together by four M4x10 screws, each with a maximum head diameter of 6.8mm. The cable dimensions are precisely 2x4mm, featuring rounded edges for safety. To prevent the cells from shifting inside the casing, insert a soft material like a sponge into the space between them. This simple solution will keep the batteries securely in place.
