The lithium battery charging algorithm consists of constant current and constant voltage stages. After the constant voltage stage, the battery should be disconnected to prevent overcharging. Periodically, the battery can receive small charges to keep it full. Figure 1 provides a visual overview of how a lithium battery is charged.
When charging batteries in series, you need to utilize a charger that matches the system voltage. We recommend you charge each battery individually, with a multi-bank charger, to avoid imbalance between batteries.
It is possible to charge the cells individually, but limit the current and don't exceed 4.2V, and monitor the battery temperature. Many lithium batteries have built in protection for overdischarge.
If the cells are protected and one cell charges faster than the other it's protection will cut it off and current will not flow the other battery in series. That is the function of battery management circuits. Lithium ion batteries are fully charged at 4.2V, and discharged at about 3 V.
During the constant current charge, the lithium cell is discharged. The cell will sink as much current as it is given, although providing too much current may be dangerous. Stay at or below the limit specified by the datasheet. A standard charge on a datasheet is typically defined as 0.5 C, where C stands for capacity.
At some point, the 3.6 V of a single lithium ion battery just won’t do, and you’ll absolutely want to stack LiIon cells in series. When you need high power, you’ve either got to increase voltage or current, and currents above say 10 A require significantly beefed up components.
