Second; Hi Adam, I may have asked before in one of our emails but why are you using IGBT's? It is my understanding,(which is limited at best when it comes to controllers), that they are hard to get to work together in parallel. Is this not true? I know the Zilla uses them but they are the TO-247 ones I think. Got to look inside a Zilla a few months back. I guess I'm trying to figure this out as far as which would be the best way to go for the "Orion"
Here is a few pics for those of you who have not seen her.
OK maybe not, ??? apparently I'm missing a security token????????
Contact me if you want to see some pics of my ground up composite build.
A group of us got together and picked up all 28 modules for about $20 a piece in a group. So were working with what we have. lol

These modules will take a little consideration in putting them in parallel because you have to keep them at the same temps. Im planing a copper layer in between the copper and heat sinks to evenly spread the heat.

The nice thing about IGBT's is their high voltage ability. These can handle a battery pack with a nominal voltage of 400V!
