Blend Micro, powered by Lipo battery, which will charge when connected to USB


#1

Is it possible to power the Blend Micro with a Lipo-battery, which will be charged when connecting the Blend Micro to an USB port? I need a solution for a product where there is no possibility to take out a battery for charge/change, and the only thing exposed will be the USB port.
I have found this (Adafruit Pro Trinket LiIon/LiPoly Backpack Add-On, https://www.adafruit.com/product/2124) and was hoping that this is something that could function for the Blend Micro?
