To supply a pulse of this power, a capacitor of at least 22,000 microfarads would be required. This is a rather big capacitor - probably about the size of a coke can. One problem with using a capacitor this size for intermittent applications like this is that a cap of this size will have significant leakage current, causing battery drain when not in use. As regards batteries, Alkaline, NiCd or NimH cells of AA size or above should be able to supply this current quite easily. Your idea of using remote control car packs should work fine.
