    @akshay66 : Well 200Mah will definitly be more than sufficient actually. A 200mAH will not be

    @sushmair : better go with a SLA battery. 2AH +.

    1) you can use the normal 1.5V AA size battery (yes, the Rs 8.50 battery) if you are on a budget. connect 6 of them in series. People normally underestimate these batteries.
    2) Use one of those Lithium batteries (you can browse for them at online shops) if you need to save space and weight. But then, your expense will rise up. You will have to buy the charger too.
    3) You can use two AAA batteries for the microcontroller supply. Hope you are not using the good old 89c51.
    4) Dont use alkaline batteries/9V batteries for motors which takes in more than a 50mA.
    5) You can also use NiCd/NiMH batteries in series. They are real good, but since they are 1.2V a piece, will consume your space.

    This is good info. Thanks all!

    @allbits,

    I have noticed that almost all RC toys use the standard AA size (1.2v) batteries in series. Technically, why do they score over, say 9v batteries?

    Current.

    These batteries can give more current per time. Motors needs current, so if your battery cant give much, they dont run.

    9V batteries cannot deliver that amount of current. Yes, the battery chemistry is different.

    if you need to know more about batteries, go through this.
