Correct, the current limit of the LT1963 is 1.5A, so it would not be able to power the other RPis. Everything seems to be running fine with the Zero W/Kali/ProtoDAC. No undervoltage warnings.
For the Zero W/Kali/ProtoDAC stack about 8 hours. I am going to run the Zero W on a separate power supply and estimate time with Kali/ProtoDAC. Kali has a jumper that splits the RPi and Kali supplies. I am pretty sure ProtoDAC alone would run for days on a charge.
