Project with mp3 and gps shield

Hi all, my name is Ruben, this is my first post :) i bought my arduino board 1 week ago im reading and learning, im following a manual with how to start with arduino, the basic tutorials, but i have a little project in my head for the future and maybe you can help me, this summer i wanna try to put a gps shield in my arduino and mp3 shield, wanna make a sport tracker with the gps and listen music with the music shield, i have this 2 shields because i bought a arduino kit with some shields and items:

it will be possible to supply with a battery, thank you so much and excuse my english im spanish.

I forget to say about if its possible to have this 2 shields working in the same time with the arduino one

I guess you mean the Arduino UNO, the answer is yes. The pin usages of the two shields don't interfere.

Depends a lot on the batteries used and how you connect them to the Arduino. Don't use the onboard linear voltage regulator, it wastes too much of the energy.

Thank you so much pylon. Yes, i mean arduino uno sorry i translated the name haha because uno is one in spanish, sorry about it. I was thinking in this battery, what do you think about it :

Someone can help please¿ :)

That battery should be adequate. But all together, that will be a handful. And, I suppose, you'll need an LCD, too.

This battery should last about 3-4 hours having all components in continuous use. Don't forget: If you connect it to the power connector of the Arduino (the voltage is high enough for that) you waste about one third of the battery's capacity to heat the board. You should look for a switching voltage regulator, they loose much less energy.

After couple of weeks at last i have here the shields, i wanna make this project this summer, i quote you because i have a lcd, it will be possible have this 2 shields and the lcd running in the same time with the battery? The LCD i only want to see the track of the MP3 and so on, thank you for all guys.

The display adds another ~75mA to the calculation. So according to the datasheets you have about 230-370mA (specification sum up) of current consumption. Putting this battery to the power connector of the Arduino you'll loose at least the voltage drop on the linear voltage regulator, heating the board with about 550mW, so it might get quite hot.

But to answer your question: yes, it should be possible.

Wooow, thank you friend, and how will be the durability of this battery if have to suply the lcd, arduino, gps and mp3 shield?

If you connect it the simple way (using the linear voltage regulator of the Arduino), I would expect about 4-5 hours. With a switchting DC-DC converter my expectation epands to about 6-8 hours. That's a rough estimation with just the datasheet values, maybe the measured currents are different than what the datasheet promised, than these values may change significantly.
