Batteries Question

[IvPalmer]

Greetings!

I have a question about batteries. I'm currently building a saber using a Petit Crouton 2.0, a Rebel Star LED and this speaker http://www.thecustomsabershop.com/MH...lder-P766.aspx

My problem is that I do not reside in the US, wich means I cannot order batteries from the shop, and i'm having a really hard time finding 3.7V Lithium batteries here . So my question is, is there any other kind of battery I can use? I was going to use a CC power source at the university lab to test the board but i'm really afraid to toast everything!

Thanks in advance!

You would have to loof for lithium-ion batteries somewhere in Brasil. They should be easy enough to find. Just search for "LI-ion AW 14500"

Thank you! As for the Voltage, is there any working range or basically just around 3.7?
