thanks Paul!. I got the 1ka control board running today. Had to fool the traction voltage sensing and hardware undervoltage circuits as i'm just bench testing. I mounted the melexis current sensor on a piece of 20mm x 10mm copper bar as per the photo and shorted out a fully charged 7ah gel battery. It managed an impressive 162amps according to rtd.

I'm tentatively looking at 4 of these for the power stage:

Now, Cole, when you shift the gear and that little needle on the ammeter goes into the red and reads 2000 Amps, that's bad.
