I don't have R2018b on my machine, but I assume the model is similarly constructed in newer releases.

Inside the Battery Cell, there is a custom "Main Branch Voltage Source (Em)" block, where you specify some key parameters of the battery. Looks like "No-load capacity at 0 degC, C0:" is the key parameter that allow you vary the capacity.

Please read the notes of the block and its source code to verify.
