these are the parts you need to build the best damn 12v power supply for lipo charging or anything else.
Instructions for getting the PSU to power up are here. After you get the PSU to power up, simply solder 12 gauge silicone wire to the 12v and ground output pads, then solder an XT60 or 4mm bullet connector to the wire, depending on which connector your charger takes. Of course, you can solder on any type of connector you want... for example, a barrel plug can be useful for powering accessories that were originally intended to work with "wall-wart" style transformers.
The items above are the minimum that you need to get the charger going. But if you want to go further, check out what I built! I don't have a set of instructions for how to build this. Frankly, since it involves working with mains power, I'm not sure I will ever make them! But if you want a list of parts that I used, here they are.
