Hello My name is Alexander who is a professional electrical engineer, and I have rich experience in developing smart phone charger using battery pack. We can use MCP73831 (battery charging controller) and 1 MOSFET. Actually I have confidence to complete your project successfully. For now I have small question for your project. - Do you have detailed spec for that? - How many voltages is the battery pack you designed? - How many is the dimension of board you expect? If you are interested in working with me, please feel free to contact me to discuss the project in more depth. Thank you. Best regards.
