  • Charging Current (500mA Max): The module can deliver a maximum charging current of 500 milliamperes. The actual current may vary based on the capability of the connected solar battery.
  • Charging Cutoff Voltage (4.2V): When the connected lithium battery reaches a voltage of 4.2V, the charging process is intelligently terminated, preventing overcharging and protecting the battery.
  • Operating Temperature (-40 ~ 85℃): The module is designed to operate reliably in a wide temperature range, from extremely cold conditions to high-temperature environments, ensuring its functionality in various climates.
  • Requisite Battery (3.7V lithium battery): This module is specifically designed for use with 3.7V lithium batteries. Users should take note of the maximum permissible charging current for the lithium battery to ensure safe operation.
  • Charging Indicator: The module features LED indicators to communicate its status:

    • No Battery: When there is no connected battery, the Red LED flashes to indicate the absence of a battery.
    • Charging: During the charging process, the Red LED remains illuminated.
    • Done: Once the charging process is complete, the Green LED turns on, signaling that the battery is fully charged.

This internal operation of the CN3083 IC-powered solar charger module combines intelligent charging, safety features, and user-friendly indicators to provide a reliable and efficient solution for harnessing solar energy to charge 3.7V lithium batteries.
