When choosing a lithium battery, it's important to consider the battery capacity. The charging current and charging voltage for a lithium battery are dynamically changed based on its structural characteristics. The maximum charging termination voltage should be 4.2V. Do not overcharge, as this can damage the battery and pose a serious danger.
For lithium batteries, a good charging current is generally between 0.2C and 1C, with 0.5C being a commonly selected balance between charging time and charging safety. Most constant-current charging currents fall within this range.
Lithium-ion batteries are made of two electrodes: a positive on e, and a negative one. When we charge the lithium batteries, the electrons are sent back to the anode and the lithium ions re-intercalate themselves in the cathode. This restores the battery’s capacity. Fully charged battery voltage: Lithium ion Batteries: 4.2V Per Cell
When charging, the difference between the battery voltage and the maximum charging voltage is less than 100mV and the charging current is decreased to C/10, the battery is deemed fully charged. C depends on the battery pack or battery cell specifications. The temperature range of lithium battery charging : Lithium ion Batteries: 0~50℃
Lithium-ion cells are supposed to operate between 0% and 60% RH. According to the industry standard, the cycle life of a Lithium-ion cell is defined as the number of charge-discharge cycles of the cell by the time it reaches 80% retention capacity of its original capacity. The recommended Depth of Discharge taken for the cycle life testing is 80%.
This charge curve of a Lithium-ion cell plots various parameters such as voltage, charging time, charging current and charged capacity. When the cells are assembled as a battery pack for an application, they must be charged using a constant current and constant voltage (CC-CV) method.

How Much Current Is available in Series-Connected Batteries?
$begingroup$ What would happen to the available current of the battery, if one of the cells was not at the same V level or charge capacity as the other 2 cells (e.g. 1 cell was 3.9V@75% charge & the other 2 cells were 4.2V@100%). The battery V would be less than 12.6V (as would be the case for 3 fully charged 4.2V cells), but how much less?
