Could you (or anyone else) point me to some documentation about fex files? Or describe with a litt ...

Install Ubuntu on VM for example.
After thath git clone sunxi-tools from GITHUB and compile it.
You'll get here 2 files (fex2bin and bin2fex) for converting fex files to bin
fex files edit only in linux or notepad++ on windows
After edition conver file to bin for example [root]: fex2bin script.fex script.bin and copy it to fat directory of SD card.

has anybody tried something similar to that? And nope, Not power banks. I just want to fix it to the Battery interface :c

Most likely yes, but you will need to solder wires / connector to the board. In theory you can use any 3.7V battery.

Go with something like this than you can use it as USB power, and even use the 12v to power a screen.

Thnx for the replies

and (sorry am a newbie) umm Think suddenly the electricity dropped, and as soon as it drop, I want the pi to power up using the battery connected to the battery interface.(it should power up the pi as soon as the electricity drops and shouldn't interrupt the on going processes.) idk if my idea might work, but i need your ideas coz am a newbie ._.

That is possible. But it would be easier to just buy a UPS. Just go to a website that would sell them IE. Staples.com, walmart whatever.
Pick out one thats 30-50 bucks, when you get it. Pllug your usb adapter into it. Bam, power goes out, and your device will stay on.

It is easy. Get a 5v battery, a charger that suits its type (liion etc),solder it to the Vcc and gnd gpio pins, then connect it to the charger, it should be powered on if the lights are out. Check this - http://www.digikey.com/en/articl ... um-battery-charging

He doesnt want to power the device with the battery all the time. He wants it too automatically switch to battery when the power goes out.

The result should be the same but if he really needs it, then he could use the old diy inverter + battery set up
