BQ34Z100: Parameter Adjustments for Changing from 11S1P to 11S2P

Part Number: BQ34Z100

Tool/software:

Hello TI team,

We previously used the BQ34Z100 with an 11S1P configuration using IFR26620-33A cells and successfully completed the Golden Learning cycle. Now, we plan to change our battery pack to 11S2P.

Before performing a new learning cycle, we would like to know:

  1. Which parameters in the .gg file need to be modified to account for the increased parallel cell count?
  2. Are there any special considerations for running the learning cycle in this new configuration?
  3. Do we need to reset any specific registers before starting the new learning process?

Any guidance on the necessary adjustments and best practices would be greatly appreciated.

Thanks!
