Fire: I hate to tell you that even when he runs practice packs, he still puts the hurt on everybody. He is a sponsored driver for a reason-- HE WINS!!! It is not because of his "superior" battery packs. It is called skill, and years of hard work.
People need to stop whining about "superior battery packs" or "unavailable tires" and spend more time practicing and working on their setups.
I happen to know the person you are referring to, and I do know that he puts a lot of effort into racing and that is the reason for his success, not some magic parts that people can't get.
BTW, I have seen the numbers on the packs, yes they are good, but not really any better than any premium packs that they sell off the shelf.
