I am thinking a DC-DC converter that will take a wide input and constant voltage output into a nice temperature compensated resistive load. What voltage range do you want?
Doh!, that would be a constant power load. You want constant current load. Have to continue thinking...

Have to think on this a bit. I have used hot water heating elements and coils of wire (in a bucket of water) for high wattage resistors but obviously not constant current.

Anyone know of a inexpensive do it yourself way to make a dc constant current electric load for testing power supplies, lithium batteries , etc ? Looking for something maybe 2kw+ and the cheapest premade thing I can find is $3500. Maybe I'll just use a carbon pile load but that will be much less accurate.
