Hi;

I was wondering if my battery (http://www.accushop.at/products/en/Rechargeable-batteries/RC-model/Racin...) could be used on the PicoBorg?

Its 7,2V but im not sure about the amps?

The PicoBorg should work fine with that battery, you will want to check that the devices it is powering (such as motors) will handle the 7.2 V supply.

The current draw (amps) will depend on what you are trying to drive, as long as all four drives do not try and consume over 2 A things will be fine, if they try and draw more the fuse will blow (to protect the PicoBorg and the Raspberry Pi).
In simple terms the battery will provide as much power is asked for at a given voltage, it adjusts the power by adjusting the amps to get the right level.

With batteries they will usually quote amp-hours (Ah) or milliamp-hours (mAh), this tells you how long the battery will last (1 Ah is 1000 mAh).
For example, if you have a 0.5 A draw, and a 1000 mAh (1 Ah) battery it should last 1 / 0.5 = 2 hours.
This battery is 4500 mAh (4.5 Ah) and at a constant 2 A draw would last for 4.5 / 2 = 2.25 hours.
