Post-Printing Solder short leads to the battery contacts and bend them to fit easily into place. Solder the negative contact lead to the left side since that's where the cable needs to connect in the holder. Use superglue to secure the contacts within the holder. Cut and tin the cables to a suitable length. Glue the TP4056 module into the holder, then solder the leads to the B+ and B- contacts, double-checking the polarity. You're done!
