Like what batteries are being used, programming nominal voltage, How long should it be allowed to sag down, etc.... If you all really want voltage monitoring, I could include it. I was just trying to keep things simple (and cheaper) at the moment. I could easily spend 6 months on features.

I was thinking of the low voltage cutback to protect the batteries. If the batteries sag my BMS will sound the alarm anyway. I don't feel strongly about low voltage cutback - not worth a lot of extra work.

What I had in mind was a basic board that just ran the igbts to get the details of that worked out. Programming max motor amps and current ramp rate wouldn't be a big deal.

I plan to test this unit in a daily driver. I would like to be able to set full throttle around 1000 amps and also have enough control on the low end to smoothly parallel park (An economy/power switch wouldn't be a bad thing).
I don't want to cause extra work but I feel there has to be enough end user control to allow people to tweak to their individual vehicles and driving styles.

I was just going to include a basic serial port like before, and send a stream of data. If it conforms to the RTD stream, it could use that.

Yep that would be great.
