Comparing two sets of parameters (Chen2020_composite Vs my own edit) but getting unexpected curves

[gulzarumair]

Hi PyBaMM community,
I am new to PyBaMM and trying to understand it using my own cell parameters. I have two sets of parameters. param_IB and param-default (which is basically Chen2020_composite). My pouch cell is a bigger in size and consist of 23 parallel layers (Notebook file attached). Notebook
However, after running a simple experiment of C/3charge-C/3discharge and 3C-10 sec pulse. I found few issues
1- Ideally, the discharge should take 3 hours, however, for default parameters its taking less while for param_IB it taking way longer.
2- Param_IB cell is a bigger pouch cell, so it should have lower DCIR value (or voltage drop after 3C pulse) but simulation is showing the opposite.
Am I missing something or is there any incompatibility? Would appreciate a feedback from community.
Thanks
