+1 Price out a 4200mah Lipo and charger. You will be happier with that decision. You can run smaller batteries (1200-1800mah) if your wanting. Full size batteries really are not needed when running a crawler. Also, when you start getting into the scalers, full size packs may not fit.
I personally run venom 1800mah 3cell lipos in my crawlers. I love them and they are cheap.
