The 18650 Power Bank Charging Module is a versatile solution for powering your electronic devices on the go. With its ability to support a wide range of batteries, including 4.2/4.35/4.4/4.5V, this module ensures compatibility with various power banks. The operating temperature range of 10-40°C allows for reliable performance in different environments. The module's high dissipation power of 22.5W ensures efficient charging, making it a valuable addition to your DIY electronic projects.
The charging process is divided into the following three processes: trickle mode, constant current mode and constant voltage mode. When the battery voltage is lower than 3V, the charging module is in trickle mode, and the charging current is 300mA; when the battery voltage is greater than 3V, the charging module enters into constant current mode, and the charging current is charged at full speed according to the set target current, and the power can be about 21W; when the battery voltage rises to the charging target voltage (for example, 4.2V), the charging module enters into constant voltage mode, and the current gradually decreases at this time, while the battery When the charging current decreases to the charging cut-off current, charging ends. If the battery voltage decreases to 0.1V lower than the target voltage after full charging, charging will be restarted automatically. (Note: voltage over 4.2V is normal, will not charge bad battery, voltage of 4.2V when the light is still flashing means not yet full, full charge is not only to see the charging voltage)
