The Facelesstech blog documents a custom LiPo battery charge/boost board for Arduino projects. It uses a TP4056 lipo charge chip with a 10A45 boost chip.
My reason for making this mash up board was I couldn’t find a good lipo charge and boost that would power my Arduino projects that didn’t draw very much power. The thing is that most power bank boards if they don’t detect that 50mah is being drawn then they shut off. This is how I came up with the idea about mashing the TP4056 and the 10A45 and putting them on the same board, I could also add in a switch to turn it on and off too. I had already been messing around with the TP4056 and designing my own boards so I had a good starting point. Lifepo4 Cell For Solar System
