I would not get it because it will be way heavy & your car will not handle well. Even the 5S 5000mAh pack I have is too heavy for my RCPD RC8. It handles much better with a 5S 3800mAh pack.
It will work. I know a guy running the Losi conversion buggy with 6S & the 2200kv but it's way more power than you can control without taking most of the power out using the ESC & radio adjustments.
