I wrote to them, asking where I can buy it. I'm hoping for relatively short periods of 1500amps, like beating people off the line on the way to the grocery store. 1500amp would have around 3-4kW of waste heat, and as I'm not making it water cooled, you might not want to do that all day. Or make a big cold plate.
