Battery Monitoring System PCB Track Help

Hi there, I’m currently designing my first PCB which is a Li-ion 3 series (12.6V) battery management system that will charge the battery cells when a car is running. I am quite confused on where to start with the tacks, mainly the thicknesses as well as constraints of the PCB. I am plannning on ordering it from PCBWay.

Any input would be amazing as well as any links to videos on the topic that would be beneficial.

I have also attatched a picture of my schematic for reference.

Thanks!
