The Battery Shield is a LiPo battery charger and voltage regulator combined into one. You can use it to power your Core with any 3.7V LiPo battery and simultaneously charge it via the USB port. The shield is built around the MCP73871 charge management controller and the TPS61200 boost converter for upconverting 3.7V to 5.0V.
Includes a simple battery that connects solder-free to the Core.
Compatible with both the Core and the Photon.
