CBA III Settings for 12V FRC battery testing

[iambujo]

Hello all - I am giving our CBA III a try for the first time. I have seen varying plots of battery curves, and I am looking for the recommended settings for our battery in the KOP. Based on the 17.2Ah/6Cell/12V settings and 7.5 A discharge rate (recommendation in other threads), the CBA software recommends not setting the Cutoff Voltage below 10.5V. Is that because of the battery type - Lead Acid?

Posted plots seem to show lower cutoff voltages, but the CBA III SW warns against it. Should I leave it at 10.5V or is there a save and useful lower value to set it to?

Thanks!
