Electrical current module

I am doing a simulation of 6 cells discharging in parallel in a pack. I do not want to assume they are all delivering the same current. The busbar attached at the top of the battery cathode is flipped and reversed coming out the opposite end on the anode side. I want to consider the effect of this geometrical consideration on current flow through each battery. I need to make a current conservation constraint on each cell terminal so that the incoming current into the anode is equal to the outgoing current from the cathode. I have a current boundary condition on the busbar tab and a voltage boundary condition on the battery terminals. Using 2 current BCs usually gives me error. How do i set a current conservation condition on 2 seperate terminals (anode current=cathode current) in Comsol?
