Hello Toshirio-san,

You don't need to monitor parallel cells. Just treat it as one cell.

Thank you for your feedback but, could you let me know why we can treat it as one cell even though these are placed parallel.

best regards,

Hello Toshiro-san,

It is because 1sXp is the same 1S voltage level regardless of capacity. Please refer to battery university for additional references.
