How to Charge a Li-Ion Battery Correctly and Safely
The recommended charging rate of an Li-Ion Cell is between 0.5C and 1C; the full charge period is approximately TWO TO THREE hours. In "1C", "C" refers to the AH or the mAH value of the battery, meaning if the Li-ion cell is rated at 2600mAH then the "C" value becomes 2600, or 2.6 Amps, which implies that it can be charged at its full 1C, or at 2.6 amps

How to charge a Li-ion battery?
The post details the correct method of charging a Li-Ion battery with safe parameters. Let's learn the main points below: The recommended charging rate of an Li-Ion Cell is between 0.5C and 1C; the full charge period is approximately TWO TO THREE hours.
How to charge a lithium battery in CV mode?
In CV mode charge the battery with a fixed 8.6V Regulated Voltage. Monitor the charging current as it gets reduced. When the current reaches 50mA disconnect the battery from charger automatically. The values, 800mA, 8.2V and 8.6V are fixed because we have a 7.4V lithium battery pack.
Can a 5V power source charge a lithium battery?
Regardless of the nominal power of the 5V power source, the module can safely and efficiently charge the lithium battery.
What type of battery charger is used in LM317?
The battery charger circuit is designed for 7.4V lithium battery pack (two 18650 in Series) but the circuit can be easily modified to fit in lower or slightly higher battery Packs like to build 3.7 lithium battery charger or 12v lithium ion battery Charger. It is using LM317 and Arduino, charge current 800mA (CC) and charge voltage 8.4 (CV).
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.
Can LiIon 5000 mAh battery be charged with a lipo Charger?
I have a 7.4V LiIon 5000mAh battery. Max charge current is 2.0A. I read that liion can be charged with a lipo charger. But do just I need to set the end voltage to 3.7v (instead of 4.2 for lipo) and then charge away at 2A? Lipo and li-ion use same voltage. 7.4v is 2 cells in series. So charger should be set for 8.2v (4.1v per cell)
