bq20z65 cell balancing

Dear Sir,

I am developing a battery pack - Li Ion 14V8 8800 mAh - which uses a bq20z65 gas gauge ic. Actually, I am updating the product from the bq2040.

I understand the cell balancing function can extend the battery life.

Is it possible to predict how much the battery cycle life will extend? 5%, 10%, x%?

Thanks

Ronaldo
