Sure, your flashing, chip-tune playing t-shirt is really cool at the party... but at some point you need to turn it off. And yes, you could just pull the battery, or maybe you've even sewn a LilyPad slide switch in-line. Wouldn't it be nice if there was just a switch on the battery? Well look no further.
This LilyPad Coin Cell Battery Holder has a small slide switch installed on the board, in-line with the power so you can shut off your project and save batteries. This slide switch is the same as is found on the LilyPad slide switch board, so it's not easy to accidentally turn off or on.
Just like the original Coin Cell Battery Holder, this simple board holds a 20mm coin cell battery (such as a CR2032) and gives you 4 connection points (two positive and two negative) for sewing into your project.
Package Includes:
1 x LilyPad Coin Cell Battery Holder CR2032 Battery Mount Module
A small, but mighty power supply. This board was designed to be as small and inconspicuous as possible. Pop in a AAA battery, flip the power switch, and you will have a 5V supply to power your LilyPad circuit. Good up to 200mA. Short circuit protected.
This board has AAA battery clips but can use an input from 1.2V to 5V.
LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable - but be sure to remove the battery!
Package Includes
1 x LilyPad Power Supply Converter Module AAA Battery Step up to 5V

What's in the box?
1 x Battery Holder with On/Off SwitchDO NOT put any non-rechargeable battery, like dry cell, into the battery holder. Serious consequences including explosion may occur if you try to charge a non-rechargeable battery.
SAFETY MEASUREMENTS:
- Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they're not properly recharged or used.
- Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery.
- Do not mix use old batteries with new ones, avoid using batteries of different brands.
- When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.
- Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first.
- Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.
