I need to put this button here for Handy app users. Thank you!
Since I have some 21700 and 18650 batteries lying around, which I will use in future projects, I decided to make a small powerbank that can be easily attached to any battery using magnets.
5*3 mm magnets are used.
I bought the board on AliExpress, type LX-LBC3.1
Assembly steps:
1. Print.
2. Solder the magnets (very quickly). The soldering area must first be degreased and sanded.
3. Thread the wires into the case.
4. Do not insert the board all the way to solder the wires.
5. Solder wires. Push the board all the way in.
6. Check the functionality.
7. Glue the lid.
8. Enjoy.
I also made a second version of a small powerbank based on the same board -
