The temperature rise will depend on the balancing current used and the cell voltages during balancing as well as the package thermal characteristics. See thermal data for the package in the data sheet. The package is not a high power package however, so realize that the thermal resistance will be rather high and the allowable balance power will be limited. The 85 deg C maximum recommended operating temperature may also limit the balance current or power for a system.
