LED power suppy help?

I am plan to run 4 leds in a seires parallel configuration. The leds have a forward voltage of 5.2 and run at 350 ma. Would it draw more power if I had a higher input voltage or would it still draw the same amout. I am trying to decide between lithium ion batteries and NMh.

lithium - expensive yet powerful NiMh - inexpensive, fairly powerful NiCad - dirt cheap, poisonous, can take heavy abuse
