1. Find out how many amps your motors draw in total. Lets say the total is 10 amp per hour draw, then you need a 10ah battery for it to last one hour continuous and a 40ah battery for it to last 4 hours continuous. ( this does not take into account the electronics current draw)
What exactly are you building , some giant robot , ;) ;)???
2. Google search it for a while , it should probably answer you.
