The LilyPad Coin Cell Battery Holder is a sewable power module designed for wearable electronics and e-textile projects. It securely holds a standard 20mm CR2032 coin cell battery and features an integrated slide switch that allows users to easily turn projects on and off without removing the battery. Designed for use with LilyPad development boards and conductive thread circuits, the holder provides four large sew tabs—two positive and two negative—for convenient integration into fabric-based designs. The reinforced battery connector improves durability and helps prevent accidental battery disconnection during use.
