LED Concert Lighter

Step 11 Finalizing Battery Pack

Now that our Battery pack is partially inserted and the tape is removed we want to solder our wires from our LED to the battery.

It is important that the wire coming from the long lead of the LED goes to the Negative terminal on the battery because if you get the switched around the LED will not light.

Once you have the wires soldered to the Battery you can push the batteries all the way into the lighter taking care so that you push them in evenly now that they aren't taped together so we don't break the solder joint at the other end of the pack.

Depending on how much of the Divider you were able to remove earlier will denote how far in you can push the batteries.

NOTE: Once those batteries are in there you cant get them out without damaging them so make sure your light works before you push the batteries all the way in.

soldering batteries?!?! dude, you might wanna warn people that this could be pretty dangerous, that is unless you're a fan of battery acid

Already mentioned before about being careful when soldering batteries, and if you aren't confident that you should use conductive adhesive or another means to connect them.
