does anyone use really big batteries?

the 1y is 2200kv which is high but it is not so high that it will overheat with normal gearing. Gearing plays a huge role in heat as well. you can have the lowest wind there is and gear it up to high and it will still ever heat. You have many people that are very very knowledgeable telling what motors will work. You also want to choose your voltage according to the wind of the motor. In a muggy a 1515 will be plenty powerful and will run cool. Just choose a kv for your battery setup. the max is 60000rpm on the neu motors. kv * battery voltage = max rpm motor will produce. Get that around 50000rp and you are good. 60000rpm is max but you dont want to constantly run it there. 50000rpm is a good medium. ex the 1515 1y is great on 5s. the 1515 2.5d is great on 6s.
