Actually the two LP-E6 batteries in the grip are connected in parallel, doubling the amps.
When using AA batteries they are connected in series to add up to the right voltage, and the amps for each of these batteies is as stated on them. I gather the small excess voltage is regulated by a diode, dropping it down to a safe voltage.
