LTM8061EV-8.2 2 Cell Charging

Hello! 

    I am currently designing the circuitry to power my rover. I want to use the LTM8061EV-8.2 to charge two 18650 li-ion batteries in series. Upon researching li-ion batteries, I learned of balance charging. The datasheet does not mention anything of balance charging. The "typical application circuit" connects to the 2-cell in series as it would if it were a single cell. Does the datasheet assume you have some sort of balancing at the battery pack? Or is balancing not required for series connection?

Thank you for your help.
