How 11.1v 20ah Li-Ion Rechargeable  Batteries Make?

Introduction:

11.1V lithium-ion battery pack belongs to multi-series and parallel lithium-ion battery pack. It is widely used in solar, wind, water and other new energy storage manufacturers, which can play a very good role in protecting electrical appliances.


11.1 is the nominal voltage, the lowest voltage is 7V, and the highest voltage is 8.4V. The interior is composed of two lithium-ion batteries. The maximum voltage of a single lithium-ion battery is 4.2V and the minimum voltage is 2.75V. If the voltage is lower than 2.75V, the battery will be discarded and cannot be charged, otherwise it will be dangerous. Likewise, a single lithium-ion battery can not charge more than 4.2V, otherwise it will be dangerous.


Therefore, a charger should be designed to ensure that a single lithium-ion battery does not exceed 4.2V, charging input, 12.6V power supply.


Detailed description of three classical 11.1 lithium-ion battery charging circuit diagrams (11.1 lithium-ion battery charging chip)


When charging, the red indicator lights up and the green indicator lights up after filling.


High energy density, high voltage, pollution-free, lithium-free metal, high cycle life, no memory effect, fast charging.
