Wiring Questions

[Chubby Cheeks]

I'm making a no sound, basic lightsaber without flash on clash and I already ordered four 3.7 Volt Trustfire batteries, a 4 AA battery holder, a 1000mA 4-wire BuckPuck, and a Luxeon Tri-Rebel Star in Blue/Blue/White from TCSS. I was wondering how much of those batteries would be required to fully power the LED. I also did not order any dummy cells since they were out of stock, so if I need less than four batteries, I believe I would need something to complete the circuit. Any suggestion would be fine. Lastly, I am wondering how I would wire the whole thing in parallel. I saw the video on TCSS's YouTube channel, but I'm not sure if I understand it or not. If someone can draw me a diagram or a description of the circuit in parallel and series, it would be much appreciated.

With the BuckPuck? Using 2 li-ion cells is sufficient, although you *can* give it all 4. It won't work any better or worse, it'll just take longer to charge the batteries I believe.
