I don't think it would be a good idea to run a stock kraken at anything over an 8.4.
On the bright side, it fits a large battery, so you can get mega mAh-age going on and not have to worry about batteries dying during a game.
www.cheapbatterypacks.com is your friend. If possible, try to do a group order, it'll save you on shipping
*edit* oh yeah, screw the stock connector and convert to deans
