rookie with first time brushless conversion/hyper 7

[halfcab]

ok, been reading a lot and it's a lot to digest.... so what I have so far is a very clean hyper 7, mmm v1 with a cc bec, neu 1515 1yf, an rcm motor mount and 13t mod 1 pinion, batteries are what I'm concerned with, what should I run with this setup? any other suggestions would be welcome

it's not for the track it's for bashing and showing up friends with their brushless slashes
