Support requested for unrealistic results following CHT tutorial

I’m trying to complete the Tutorial: Battery Pack Cooling of an FSAE Car, however my results do not match the expected outcome. I’ve double checked the instructions from the tutorial, but I can’t pin point what I’m doing wrong. From the electric potential view, it seems like there is an open contact in the string. And air flow is way lower than expected.

My project is located here. Any guidance is appreciated.
