How Charge 11.1v 18650 Li-ion Battery Packs?


first of all, we should have a brief view of 18650 li-ion battery movements.

18650 li-ion battery movements:

The working principle of lithium ion batteries refers to their charging and discharging principles. When the battery is charged, lithium ions are generated on the positive electrode of the battery, and the lithium ions are moved to the negative electrode through the electrolyte. As a negative electrode, carbon has a layered structure. It has many micro-holes. The lithium ion that reaches the negative electrode is embedded in the micro-holes of the carbon layer. The more lithium ions are embedded, the higher the charge capacity is.

Likewise, when the battery is discharged (that is, the process of using the battery), the lithium ion embedded in the carbon layer of the negative electrode is released and moves back to the positive electrode. The more lithium ions returned to the cathode, the higher the discharge capacity. What we usually call battery capacity refers to is discharge capacity.

It is not difficult to see that in the process of charging and discharging lithium ion batteries, lithium ion is in the state of movement from positive to negative to positive.

made by 3 18650 battery in series, 11.1v li-ion battery pack should has same battery ion movements.

How to Charge 11.1v battery pack?

11.1v li-ion battery pack has proper battery management system. special designed battery pack should use corresponding charger, CC-CV charge within proper parameter. 

charger notes: do not use lead acid charge to charge 11.1v li-ion battery pack. do not use 2A above charger.
