Henryuan lithium battery chargers: 
When it comes to maintaining the health and longevity of your lithium battery pack, understanding how lithium battery charger voltage corresponds to your lithium battery pack is critical. The voltage of the charger plays an important role in the charging process and can greatly affect the overall performance and lifespan of the battery pack. In this article, we’ll dive into the importance of matching charger voltage to battery pack voltage

Lithium battery packs come in a variety of voltages, such as 3.7V, 7.4V, 11.1V, 14.8V .etc When choosing a charger for a lithium battery pack, you must choose one that is designed to match the voltage of the battery pack. Using a charger with a different voltage can result in overcharging or undercharging, both of which can harm the health of your battery pack

Overcharging a lithium battery pack may cause irreversible damage and create a safety hazard. The charger voltage must correspond to the battery pack voltage to ensure that the charging process occurs within safe parameters. As lithium batteries become increasingly popular in a variety of applications, the need for accurate information about charger voltage and its relationship to the battery pack continues to increase.

Conversely, undercharging a lithium battery pack can result in reduced capacity and performance. Using a charger with a lower voltage than the battery pack may result in an incomplete charge cycle, ultimately shortening the overall life of the battery.

To sum up, the corresponding relationship between the lithium battery charger voltage and the lithium battery pack is a key factor in maintaining the health and longevity of the lithium battery pack. Understanding the importance of matching charger voltage to battery pack voltage is critical to ensuring safe and efficient charging and maximizing battery pack life and performance.

 For lithium batteries, Charging voltage =  the number of series connected batteries X 4.2V.

Such as
1 cell 3.7V lithium battery charger voltage 4.2V = 1*4.2V

2s 7.4V lithium battery charger voltage 8.4V = 2*4.2V

3s 11.1V lithium battery charger voltage 12.6V = 3*4.2V

4s 14.8V lithium battery charger voltage 16.8V = 4*4.2V

5s 18.5V lithium battery charger voltage 21V = 5*4.2V

6s 22.2V lithium battery charger voltage 25.2V = 6*4.2V

7s 25.9V lithium battery charger voltage 29.4V = 7*4.2V
10s 37V lithium battery charger voltage 42V = 10*4.2V

12s 44.4V lithium battery charger voltage 50.4V = 12*4.2V

13s 48V lithium battery charger voltage 54.6V = 13*4.2V

14s 51.8V lithium battery charger voltage 58.8V = 14*4.2V
Regaring to the charging current, commonly the charging current is 0.2C - 0.5C, some battery packs can support 1C, C = Battery capacity.
