Thanks a lot Darice

The paper looks very interesting and I can't wait to try those models out in my project. It will take a while before I manage to incorporate them in my current coding logic though. For now, I will wrap up my investigation with the default LFPGraphite model. I notice in the code you sent that "q_relative" is "the sum of both calendar and cycle aging":battery.StateCell.q_relative = q * 1e2,
q = 1. - life_model.qLossCalendar[-1] - life_model.qLossCycling[-1]

while in the default LFPGraphite model the "q_relative" is either the cycle or calendar capacity, which ever is the lowest. N.B. this is my own conclusions from looking at the exported data while running the BatteryStateful simulations. Can you confirm or reject this observation? 

I export like this:
'q_relative': PySAM_battery_in_simulation.StateCell.q_relative,
'q_relative_calendar': PySAM_battery_in_simulation.StateCell.q_relative_calendar,
'q_relative_cycle': PySAM_battery_in_simulation.StateCell.q_relative_cycle,

See the screenshot for the results.

print(PySAM.__version__)
4.2.0

Thanks again
