12v 23A Battery holder for my LED light
I have added 2 versions - Large and small

This can also be used for other sized batteries - just scale it to the size you require

It can be simple or complex - depending on your skill level. I will provide instructions for both methods :)

You will need-
-Two wires (positive and negative)
-Superglue
-Tweezers
-Solder (complex method)

Simple Method:
Simply strip the end of the wires - because you are not using solder you will want to strip a large amount and twist it so it all stays together.
Thread the wire through the wire entry holes at the bottom of the holder. I have added holes in the side of it to assist with getting the wire through to where it is needed - i just used tweezers and poked it through :)
Once you can pull the wire right through - ball up the twisted wire into a large ball and glue it into place.
NOTE: You may have to test fit the battery a few times to get placement right prior to gluing.

Complex Method
Instead of balling up the wire you can either add a large blob of solder as i have for simplicity or you can add proper contacts and solder the wires to the contacts - i still glued the wires afterwards to avoid contact being broken at all by wiggling wires.

Remember to thread your wires through first, prior to balling them up or adding solder as they should not fit through the hole after this is done

Once you are done you can attach any kind of connector or wiring setup you need. I used JST Connectors for mine.
I also added a small hole in the bottom to assist with removal of the battery
