How to flip sign of discharging current in Simscape electrical circuit?

Dear all,

I am currently trying to connect a battery pack and a supercapacitor in parallel to test each behavior while charge and discharge current flows in and out.

However, the problem I confronted is that the battery pack circuit deals a positive current as discharge current while a supercapacitor circuit deals as the opposite.

Is there anyone who is familiar with this issue, that is, flipping sign of discharging current in Simscape electrical circuit shown in the below?

Nevermind. It seems that I misunderstood the problem...
