What is your pack voltage and what were you expecting as performance?

I am going to say that your LBV and LBVI are set too high, probably 135v for LBV and 138v for LBVI.

I have a Z1K-LV running at 96 volts, 500 motor AMPs, 300 battery amps and I am running 12x 8VGC XC floodies and my performance is pretty decent for a lead sled. I have my LBV at 78 volts and LBVI at 82 volts. I have some voltage drop that I need to take care of, but my pack never goes below 82 volts while pulling 300 AMPs up a nasty hill for about 15 seconds.

My pack voltage is 156. I'm not sure what I was expecting as far as performance but seems like it's good to 35mph then it drops off. It's almost like I have power only to 50% of throttle.

I am using the zilla viewer with my laptop and the throttle reads all the way to 100% and the controller temp is maxing out at 101 F so I'm well below the 130F cut off.

The max amps I've pulled from motor is like 400amps and only like 150amps from batteries.
I'm going to do a few more test runs to see what the controller is reading. Just need to get the wife to give it some juice and not be a girl about it. So I can monitor it running.

Which gears are you using? In my little 96 volt setup I use 1st up to 15 MPH, 2nd up to 30 MPH and 3rd up to 45 MPH cruising. I can get 55 MPH in 3rd (automatic transmission) but 96 volts is too low to maintain those higher speeds. The next EV will be a 156 volt beast, hopefully with 160 AH lithiums.
