Yea, that's understandable.
And by packs, of course, I mean 6-cells. Not sure if that was clear or not. Most everything runs 6 these days.
I guess it should also be noted that you don't need 3000s to race, but I feel like if someone is going to spend the money, it is worth the little bit extra to gain the runtime. It will make learning to drive/race that much easier, plus you'll get more use out of the pack in the long run (won't be obsolete as quickly).
