What is the best way to add Lithium batteries to a Netduino project? I need to be able to power the Netduino and connected devices via the Lithium battery and also recharge the Lithium battery via USB. I want it to all be self-contained, so that I will be able to simply plug a USB cable into the interface and charge the battery while also powering the Netduino and connected devices. What should I use?

Check out the lipo battery category on Sparkfun. They have a charger circuit as well as a range of different lipo batteries that you can use. You want to stick with a single cell lipo for this project.

I actually bought this the other day: http://www.sparkfun.com/products/10300, along with this cell: http://www.sparkfun.com/products/339. Do you know if the Power Cell - LiPo Charger/Booster will allow me to keep my project plugged in while also charging the lithium battery? I couldn't find a clear answer on that. I don't want to have to remove the battery and unplug my Netduino in order to charge it.

Easiest LiPo charger chip I've seen is the MAX1551 (http://www.maxim-ic....dex.mvp/id/4002)
