Lightsaber Battery Pack: 18650 Battery Holder

**IMPORTANT** I'm currently working out the voltages and I can't guarantee that the saber will operate properly on the 3.7v typical that a 18650 would supply. I'm doing testing now, so while this may be a cool concept, it may need some extra circuitry to actually ... y'know ... work.

Out of curiosity, I wanted to explore and see if I could design a functional battery pack for a Savi's Workshop saber chassis. I'm working on the circuit board to go in this -- just to bridge the contact points
