You're going to need a lot of heatsinking and fans anyway. Just out of curiosity, why are you bothering with an IGBT or MOSFET? Why not just a resistive load bank? If you really need constant current, use light bulbs as your dummy load -- they'll draw essentially constant current despite battery voltage changes during the test. -- Lee A.
