What cell voltage should I use to charge a 2S 7.4 V LiPo battery?

The Current setting might be a bit high. I would take that down to 2 or 3 A especially if you can accept the longer charging time. Charging / discharging cells with high currents decreases their lifetime so if you can, take it slow, use a lower current. Start learning at Battery University. Share. Cite.

To get you started: Li-ion cells are charged via a constant current/constant voltage system. You start by charging them at a constant, controlled current (less than 1C) until the voltage of the cell becomes 4.2 (or 8.4 with 2 cells in series), then you hold the voltage constant at 4.2 and allow the current to drop as the li-ion battery fills up

Charging stops when the current drops to a pre-determined rate (for example 1/10 of the starting current). Li-ion batteries do not need a trickle charge, and in fact a trickle charge is bad for the battery. Also, when charging more than one Li-ion in series, after many charges, the batteries will start to become unbalanced. This means that that

How a lithium battery is charged?

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.

How does A PMIC charge a lithium ion battery?

What is a lithium battery charging curve?

The lithium battery charging curve illustrates how the battery’s voltage and current change during the charging process. Typically, it consists of several distinct phases: Constant Current (CC) Phase: In this initial phase, the charger applies a constant current to the battery until it reaches a predetermined voltage threshold.

What happens if a lithium cell has a constant current charge?

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.

Can a lithium ion battery overcharge?

Li-ion batteries are not able to take in overcharge. Whenever completely charged, the charge current has to be shut down. A consistent drip charge might result in plating of metallic lithium and skimp on safety. To reduce strain, maintain the lithium-ion battery on the peak cut-off as brief as you can.
