To make this successfully, you need a switching usb c charging board for 3.7 volt batteries (the one I used is called a IP2312) and a 3.7 volt 5200mAh battery. place the charging board into the slot at the bottom, then slide the battery in on top. DO NOT desolder the battery terminals from the motherboard of the SP(unless you want to solder to the motherboard, which makes this a whole lot harder), just solder to them. you then need to solder positive and negative wires from the IP2312 to the positive and negative clips otherwise it will not work. Then, solder the + and - wires from the battery to the IP2312. The resistors are SMDs so you might have to order some if you don't usually work with surface mounts and would like less amperage. There is another model that works for people who can't solder SMDs.
