Wiring green Tri-Cree XP-E2

[MiniHoss]

I am planning a stunt saber build and had a question about wiring. I want to get this LED (http://www.ledsupply.com/leds/triple-cree-xlamp-xpe2-high-power-led) in green. I am getting a 1000mA buckpuck, this battery pack (http://www.thecustomsabershop.com/74v-Li-ion-1400mAh-18500-Battery-Pack-P758.aspx), and I was wondering what the best way to run it would be. I was thinking of running two of the dice in series and leaving the third alone OR running two in parallel at 500mA and tho other at 1000mA. I am familiar with soldering but less so with circuits. Can 3 dice be run in series at 1000mA each from a single buckpuck and a 7.4V pack? I imagine it wouldn't run for very long.

No, You are not going to be able to run all 3 at 1000. You should be able to run the 2 in series at 1000mA. The third will just be unused..

That's great! I figured the only way to get all 3 at 1000mA would be a 9V+ pack and I don't think I have the room for that.

That solution wouldn't work anyway.

How can these Tri-crees be operated at 1000mA?

[Forgetful Jedi Knight]

Use a good high end soundboard and the proper battery solution. You would also need the space within a hilt to fit all that in. Your other alternative could be to direct drive them, you could run 2 in series and the third on a parallel circuits. You would need the proper resistors for both the single die and the 2 dice in series. ;)

I'll keep that in mind for my next build, and keep things nice and simple for now.

Could they be wired in parallel (the 3 LEDs) and use a 5v output of a battery pack (2 li-ion 18650cells) with a 1000mAh buckpuck?

Technically yes, though each die will only get 333 mA (barely bright). If you are going to try to wire 3 in parallel, skip the buckpuck - they will get a third of the total output of the battery (which will still be a little less than 1000 mA per die).

13353 this is the battery pack, it can give 5v and 1 amp. ( I am planning to add another 18650 cell to make it 4 amps)

-My main point on using the battery pack is to use it as a charge port for the cells inside the hilt, so I only remove the pommel cap to charge it.

-How can I get a proper configuration to power the Tri-Cree blue? should I use de 5 volts output? or should I connect 3 batteries in series to get the proper voltage?

I have no idea how you would add a second battery to that, much less getting both to charge. That sounds like a train wreck waiting to happen.

13354 this is my battery pack beside my hilt, I plan to conect another battery in parallel so the both batteries can be charged with the nicro usb port on the battery pack, this will give more amps and sane voltage.

the main question is, how can I make a tri-cree blue to light up (whether if its wired in series or in paraller) becacuse I haven't use a buckpuck or a resistor before, and want to know the best configuration without messing up any phisical parts, if it is better to use the electricity out of the 5v 1A of the battery pack without buckpuck. Or from the batteries and then to a buckpuck or resistor...
