Doubtful you can buy it, but you can make one. I am in the process myself. Sure you want to do this at home? This much power is non-trivial. Be wary.
You can see Jack Rickard doing a high C discharge in a video from last fall, 1000Amps. (EVTV Motor Verks http://www.evtv.me.s3-website-us-east-1.amazonaws.com/vidarch.html) He used a 20 foot reebar bent in half. You can turn them red. Sorry I don't remember which video. I think I saw a guy doing it with a reebar on his sandy driveway on you tube, and someone else suggest a roll of welded wire in a trash can full of water. That is the sort of resistor you need to do it fast. You can buy big wirewound resistors too. For example http://snipurl.com/28uh1bm but bigger. Some people run their batteries down with their EV - jack it up and let it spin. You will want a big contactor for closing and opening the circuit, a bunch of fat wire. A JLD 404 with a shunt is very handy for measuring the Ah you are passing in and out of the cells. It has relay control outputs that are very handy. JLD 612 is a temperature controller that is good as a thermal safety. You need to be handy with the arithmetic - Ohms Law and all that. Seriously, if you don't size things right you can get hurt or burn something up or down.
