Test went well, I had to add some hysteresis to the voltage comparator so it would switch off the big CC supplies cleanly, as it would buzz for a second or two right at the switch point.
Other than that everything worked well. The PTC strip temp safety worked well, We hacked up an old BCM to get the male pin side of the PTC connector. We set the shutdown at 600 ohms, and the warning at ~50. Each of the setpoints is easily monitored and adjusted, so Ron will tune it after watching several packs
The pack I was testing on was pretty full, so the pack voltage went from a starting value of 155V to 170V in only a couple of minutes. Ron will give it a better test tomorrow.
