**electric go kart conversion. battery question!?**

hi no idea if I've posted this in the right section, but i apologise now if it is, I've decided to do some tinkering with my retired kart basically I am pulling out the honda gx160 engine from my Honda pro kart and want to fit it with a "36v 800watt escooter motor"

http://www.ebay.co.uk/itm/36-VOLT-800-WATT-ELECTRIC-E-SCOOTER-MOTOR-36v-800w-/180761403629?pt=UK_Toys_Games_Outdoor_Toys_ET&hash=item2a163820ed <-- sorry if i am not meant to link things like this it was just for explanation purposes.

and basically my question is, can i run this motor at full using 3x car 12v battery, ie

as i may have got this calculation wrong but according to what i read you take the CCA "Cold Cranking Amps" and multiply this by 12.6 to get the watts, so the battery in question produces 400 CCA x 12.6 gives me 5040 watts and with 3 of them running in series to produce the 36v ... am i getting this right before i go out and buy bits that aint going to work

thanks in advance
