Hi,
The slower SoC discharge is often due to how the battery pack calculates SoC versus the estimator. First, check the terminal voltage vs. open-circuit voltage (OCV)—terminal voltage includes the drop from internal resistance under load. If you need accurate charging behavior, use a CC-CV block for constant voltage charging. Also, review initial conditions: setting both initial SoC and initial voltage with high priority can cause conflicts, define only one.

Thanks!
