اطلاعات بیشترWhen charging a lithium-ion battery, the charger uses a specific charging algorithm for lithium-ion batteries to maximise their performance. Select LI-ION using the MODE button.
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.
To charge 4 Li-ion cells in series, the proper way is by using a charger specifically designed for that task. It should include balancing to ensure all cells are charged to the same voltage, despite differences in capacity between the cells. By clicking ‘Post Your Answer’, you agree to our terms of service and acknowledge you have read our privacy policy.
Your charger should match the voltage output and current rating of your specific battery type. Lithium batteries are sensitive to overcharging and undercharging, so it is essential to choose a compatible charger to avoid any potential damage. In addition, different types of lithium batteries may have different charging requirements.
Lithium-ion batteries have low internal resistance, so that they will take all the current delivered from the current charge cycle. For example, if you have a 50-amp charger and a single 100-amp hour battery, divide the 100 amps by 50 amps to come up with a 2-hour charging time.
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.

As Marko says you have to charge the cells in series with a CC/CV charger. This charger first pumps CC (constant current) into the battery until its voltage reaches 4.2V per cell, then it switches to CV (constant voltage) to finish topping up the charge. End of charge is detected when the current drawn by the pack goes lower than a threshold.

What Is the Best Current to Charge a Lithium Ion Battery? Charging a lithium-ion battery involves delivering the optimal amount of electrical current to replenish its energy safely and efficiently. The ideal charging current typically ranges from 0.5C to 1C, where ''C'' represents the battery''s capacity in amp-hours (Ah).

When charging, lithium-ion batteries typically use a current rate of 0.5C to 1C, where "C" represents the capacity in amp-hours. Thus, for a 100Ah battery, this translates to a charging current of 50 to 100 amps. However, most manufacturers recommend a lower charging current to prolong battery life, often around 0.2C for optimal performance.
