    Ehm, I need an EXTERNAL battery for small robot projects.

    I'm sorry, we do not know any specifications for this kind of batteries, nor we produce or sell any of them.

    Guess Robot applications can be scrapped off the list for UDOO x86.

    Actually no, it doesn't mean that.
    It just means we can't suggest you any other battery at the moment because we haven't tested any other battery.

    Ok, I wait news about it, because, if somebody wants make a robot, it's necessary an external power source.

    Not trying to be rude. But if you are smart enough to build a robot. It should be trivial to make a 12V/3A regulator and use a 16 Volt battery or something around that voltage.

    A suggestion to control 20 servos ==> Mini Maestro 24-Channel USB Servo Controller

    You could also look for a power-bank which supports 12V and 3A.. Found some of these at amazon.

    Ok, couple things to note here gang:

    1) The 12V 3A is the MAX draw. That's assuming everything is cranking full blast. During idle conditions you won't be drawing anywhere near that much (probably more like 12V 1A or less), so when factoring your battery/powerbank size, expect it to last longer than the basic calculations since you probably won't be running at full power at all times.

    2) If using raw battery packs, you can always use a buck converter to step up/down the voltage as needed (provided the converter you choose can handle the load). For instance, it's not uncommon to power your motors directly off the raw battery and then in parallel feed to a buck converter to step up to 12V (or down to 5V as the case may be for the board you're using), which also provides noise filtering. With a buck convertor you can use, say, 4 regular old AA Alkaline (4x1.5V=6V) and boost to 12V output regulated. You'll probably want to do something similar to this regardless because it will try to hold the voltage to 12V even as the batteries start to drop off due to drain (Alkalines ,for instance, will slowly drop in voltage as they drain and eventually will drop below 1.2V and then fall off a cliff.)

    Take a look at something like these:

    https://www.pololu.com/category/132/step-up-voltage-regulators (to turn low voltage to high)
    https://www.pololu.com/category/131/step-down-voltage-regulators (to turn high voltage to low)

    Pololu doesn't carry and step up/down converters that handle 12V at the current levels we need, but I'm sure they exist...

    True that.. The other ones I saw was on German-amazon and had for the "higher" output a normal cable.

    Example: https://www.amazon.de/Universal-Zus...SG/ref=sr_1_18?ie=UTF8&qid=1493825603&sr=8-18
    Look the pictures.. The 12V output is a cable, but not USB.
    Or another one:
    https://www.amazon.de/XTPower®-XT-16000QC2-Powerbank-moderner-15600mAh/dp/B01JZA76B6

    That things are built to power up laptops, disc-players, etc.

    Those look more promising, they have a more normal output cable.
