I am thinking of making an Arduino powered console. There is only 1 problem. What battery do i use?
Thanks, checkm8 
use a LIPO , the voltage really depends on your design ,most of the components work on 3 or 5 voltDC logic levels ,I would suggest a 3.7vdc 18650. OR if you want to have your design flat then single cell or dual/triple etc cell(based on votlage) lipo should be good.
but if i am using an arduino esplora and a adafruit 1.8" screen, the esplora needs 5v and the screen 3.3v to 5v, therefore making me need a 8.3v to 10v battery. Also, i would like the design to be slim, so a single cell battery would be convenient. Do they do 10v single cell rechargeable batteries?
Also, would a 11.1v battery overpower this project? Thanks!
If you like the design to be slim, you can use single cell and this step up voltage regulator

WHAT?!?! You don't add them up!
If you have 100 Arduino Esploras, it will still take 5V, just a lot of Amps. Man if nobody told you that, you would completely fry your screen and your esplora!
"Also, would a 11.1v battery overpower this project? Thanks!"
YES, ABSOLUTELY YES!
Have you ever heard of something called a boost converter? Hell you could turn a AA battery into 5V...
Look, if you don't know that much, you may just want to buy a consumer rechargeable power bank like this one
I got one for $15 at Frys that holds 3500mah and has 2 USB ports to power your devices...Simple to charge too...
And bro! PLEASE! Go to youtube and understand what volts and amps are!
