Can a 3.7v single cell power a Cree Tri-xp-e2 on a Petit Crouton 3.5?

[ZombieMacabre]

Hello everyone! I'm rewiring my Graflex which previously had a Makato LED string blade. Now I want to install a Blu/Blue/White Cree Tri-xp-e2 LED module. I'm using a Petit Crouton 3.5 sound board and I wanted use the F.O.C. set up. However I'm not too good with Voltage and resistor math so I was hoping some one would be kind enough to give me some advice if possible.
1. I have my board setup for a single cell battery power source. I'm using a Panasonic 3.7v 18650 @3400mAh. Is this enough power to use all 3 LED die's on the Tri-Cree? Or do I need to upgrade to more voltage?
2. What type of resistors should I use for the Tri-Cree Led with the 3.7v power set up. Or if I have to use more voltage what type of resistors do I use with it?
Thank you for reading and any help I might receive!

1) The single cell will work. Just remember to do the single cell hack for the petit crouton. Erv has a good video tutorial for that here:

2) I don't believe you will need a resistor for the main LED (someone please correct me if I'm wrong since I'm not 100% sure on this), but you will need one for the FoC LED. All the info for doing the necessary calculations for getting the right resistor can be found here:

Thanks man! And really big thanks for the resistor link too! I'm overdue on taking time to read that.
