For brakes you just need a Y-splitter for the throttle channel to plug in both the ESC and brake servo. There may be fancier ways to do it but that should work fine.

About the batteries: If you want a lighter battery (less capacity mah, like 5000 or 6000mah) I would agree to go with a top of the line pack for this project. The 3700mah packs in parallel lincpimp mentions would be a nice setup.

But if you are talking 10,000mah, even a 15c pack will hold good voltage at 100+ amps. TrueRC and Maxamps both would work if you want to save a few bucks. I have a 12000mah maxamps pack and it barely breaks a sweat in my Jammin CRT. But it's also kinda fat for racing, lol.
