Step 7: Assembly
Now is the time to glue in place the lamp and the battery.
I glued the lamp in place with silicon glue. It works well over a range of temperatures. The lamp will get warm with use, so hot-glue would be a poor choice.
On the other hand, a hot-glue gun worked great to glue the battery into the case. I also glued two bits of scrap foam to act as spacers between the battery and the cover.
Once the glue is cool/dry, reassemble the cover onto the case (minding the foam padding and wire handle) and put the four cover screws back in.
To recharge, I just hook up the small battery charger I already had to the two charging pins, which I noted the polarity of.
