It depends on whether the battery is equipped with a protection plate. If there is a protective plate, it usually cuts off at the protective voltage. Some protection plates have a protection voltage of 2.5V, some 3.0V. The effective capacity range of lithium batteries is generally considered to be 4.2V to 2.75V. Below 2 .75 V, we consider that there is no capacity. In fact, when it's below 3.0V, the battery has virtually no capacity.
6s corresponds to six strings. The rated voltage of ternary polymer lithium battery is 3.7V, the full voltage is 4.2V, the average discharge voltage of lithium battery is 3.85V, the voltage of 6 strings is of 3.8 V. 23.1 V, and its energy output wh is equal to The voltage multiplied by the capacity is 23.1*16, which is equivalent to 369.6 Wh, which is equivalent to 0.37 kilowatt hours of electricity.
