説明
Button Cell Charger A simple button cell charger consisting of a TP4056 Module, some Nickel Plated Strip and a 3d printed housing (optional extra 3d surround to cover wiring)... Charging Lithium-Ion Button Cells should be current limited to 20mA or lower. In this project you need to replaced the current limit resistor with a 56k ohms on the TP4056, to provide 20mA charging... Total cost under 1$ Nickle strip 0.15mm x 10 Meters can be fount on AliExpress for about €3.50. The TP4056 costs ~ 30 cents... Push the nickle strip through the slits, wrap and solder on bottom join (one for + and -)... Solder wire to + and - terminals of the PCB and connect to corresponding nickle strip... Print time ~ 20 minutes for the main housing, no supports required... A version for the USB-C TP4056 is included, the board costs ~ 80 cents... The low cost 30¢ version of the TP4056 is ideal for charging only, it does not provide over-discharge protection, use the USB-C type board if you require this. Note it also takes longer to print and depends your settings...
