Single Cell LiPo Battery Care
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!
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.
