Introduction

Note: This tutorial was ported over from the older LiPo Battery Care tutorial. Tips from the LilyPad Basics: Powering Your Project (Power Options: Rechargeable Lithium Polymer Batteries) were also added to this tutorial.

Lithium-Ion Polymer (LiPo) batteries are a favorite of ours. Very light weight and some of the highest energy densities available. We affectionately call this battery the 'car battery' because it's huge. Not physically (it's 110 grams!) but because this 6Ah LiPo in capable of outputting 6 Amps over the period of one hour! This is a very large amount of power in our low-power embedded world. Please don't confuse this with a real car battery!

Required Materials

To follow along with this tutorial, you will need the following materials at a minimum. You may not need everything though depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary. Below is a wishlist of the parts that you need to get started if you were to charge a LiPo battery and then remove the connector.

Single Cell LiPo Chargers

There are a variety of development boards and breakout boards with a dedicated single cell LiPo battery charge circuit. Below are a few examples from the SparkFun catalog that have the MCP73831. The charge IC used and charge rate will depend on the design.
