You will lose cell balancing, protection and the capability to read individual cell voltages. If you have a 2s product, it is better to use a 2s gauge.

Hi Batt
Actually I didn't need extra balancing, protection function, do you have 2 S Gauge recommend ? and I think its cost will higher than BQ27426+TS321/tlv271 ? and approximately how much ?

I can't tell you about the pricing but I would recommend the bq28z610 for your application.
