LEDs on a costume? Answered

I have never used LEDs on a costume before, my planned costume will have approximately 50 separate strands of lights on it, in two different colors. 

The way the costume is designed, there is simply no place to hide 50 battery packs (20, maybe but not 50), is there a way to attach several strands of lights to one battery pack and still light up for several hours?

I was planing on buying a long strip of LEDs that I could cut to length, what types of battery packs would I need to use? 

Any instructions, videos or tutorials would be awesome.

You need to say how many LEDs you have to make a sensible calculation - and how long you expect them to stay lit. It would be crazy to have multiple battery packs !

If you want strings of light, think also about EL wire, which is, literally a glowing string.

To start with the best option would be to use ultry low current LED's.
It might make more work but you can save over 70% of the power compared to standard LED's.
Otherwise there is no problem connecting several LED drivers or just LED's to a single battery pack, assuming all use the same voltage of course.

Just for consideration and as an example:
400 LED's with 30mA current each and a single voltage of 2.6V.
In series they would still only need 30mA but over 1000V, not something you want to wear.
In parallel they would need enough amps to require copper bars for the connection to the batter (or welding cables).
So, for obvious reasons one has to find a balance between oparating voltage and current consumption - the later can be further reduced by using high frequency flashes instead of constant on.

Check how much power your LED's need.
For example all up and running on 6V they would require 4amps.
This means a 6V battery with 4Ah would last for an hour before the lights go dim.

Yes multiple strips can be powered from a single pack. you'll wire the drivers in parallel with each other to the battery pack. Batteries needed will be determined by the needs of the LED strips.
