About this item

The LilyPad Coin Cell Battery Holder is a compact, sewable power supply module designed specifically for wearable electronics and e-textile projects. It holds a standard CR2032 3V lithium coin cell battery, making it ideal for low-power microcontroller boards such as the LilyPad Arduino. With its circular form factor and large sew tabs, this module integrates seamlessly into fabric-based circuits, allowing conductive thread to be used in place of wires. The holder securely locks the battery in place to ensure a reliable electrical connection during movement or daily wear. It is designed with reverse polarity protection, helping prevent damage to connected components if the battery is inserted incorrectly. This battery module is especially popular among designers and makers creating light-up clothing, interactive costumes, or sensor-based textile art. It is small, lightweight, and unobtrusive, yet durable enough for frequent use. Whether you’re prototyping a soft circuit or building a finished wearable product, the LilyPad Coin Cell Battery Holder provides a reliable and easy-to-integrate power source.
