A true equalization should NEVER be done automatically, as the high charge voltages could easily overheat and damage the battery, and/or boil the water over the top. There is also no reason to do a regular equalizing cycle if the SG stays the same across cells(it should). Doing so would be overcharging and damaging to the battery.

Lithium ion batteries are becoming increasingly popular and require a different equalization voltage than lead acid or nickel-cadmium batteries. Battery equalization voltages for lithium ion battery packs should be between 1.8 and 3 volts per cell in order to maintain performance.
How often should a battery be equalized charged?
The frequency of equalization charges depends on the usage of the battery. A good rule of thumb is to gauge how often your battery is fully charged. If your battery regularly reaches a full charge, it will need an equalization charge less frequently compared to a battery that is not used as often. Some manufacturers suggest the equalization charge should be carried out twice a year or as necessary.
