The minimum voltage for lithium batteries is around 3.4V1. The maximum voltage of the cell is 4.2V and the "nominal" (average) voltage is 3.7V2. As the battery is used, the voltage will drop lower and lower until the minimum which is around 3.0V2. By default, all the lithium ion cells will have a nominal voltage of only ~3.6V. This voltage can be allowed to go down up to 3.2V when fully discharged and go as high as 4.2V when fully charged3.
