I want to wire up a miniature wargaming figurine to have 20 LEDs. As I've poked around options my concern is the battery life and how often the battery would need to be replaced. Since each gaming session lasts 4-5 hours, it'd be great if I could find a battery that would last multiple gaming sessions (though I think this is impossible...)
I'm VERY NEW to all of this so I would appreciate explanations/solutions that understand I have little knowledge of the terms or techniques (I still don't understand what current is...)
EDIT: Here are more details on what I'm trying to do
Locations for the lights would be (and their specs):
- 8 blue for right arm (3.4V, 20mA)
- 2 Red-Blue-Green for the eyes (3.4V, 20mA)
- 10 red/orange lights for left arm and engine (2.2V, 20mA)
So altogether that's 20 LEDs, all at 20mA and none above 3.4V.
The battery would go inside the torso -- I can't find an exact image but the dimensions are roughly 2" wide, 2" tall, 3" deep.
My concern is battery life, as I'd like the batteries to last at least a few game sessions (so let's say 10-15 hours). I don't mind replacing or recharging a battery, but there's no point if I have to do it halfway through a game.
I should add that I don't know how bright these LEDs are (the specs say 8-10,000 mcd for the blue ones), and that I don't know how to dim them, but would prefer them bright since they are usually in a well-lit room.
