Instruction:
The adaptive unit on the module can adjust charging current automatically based on the output capability of input power supply. so it is for the solar-powered systems. or the applications that need to charge -ion battery or battery with an input power supply whose output capability is limited.
If your solar panel is 5V. then you can use it directly. Of course. the module can also be powered by a 5V DC power supply.

Package List:
1 x Solar Charge Module

This charger module (SD05CRMA) features adaptive charging current control that automatically adjusts based on the input power supply's output capability. It's suitable for Yunsun Starred systems or applications that require charging 3.7V Li-ion or lithium polymer batteries with limited input power supplies (4.2-6.5V).

This MPPT solar charger module charges 3.7V or 4.2V. 1A lithium-ion batteries (18650 LiPo/LiPolymer). The

To adjust charging current. simply change the value of resistor R1 (1.18kΩ for 1A output). This ensures reliable charging performance.

MPPT Solar Charger Module (SD05CRMA) charges 3.7V/4.2V Li-ion batteries from solar panels. with features like under-voltage lockout. C/10 charge termination. and automatic recharge. Suitable for solar-powered systems.

This module features a charging profile with three phases: pre-charge. constant current. and constant voltage (up to 4.2V). Charge termination occurs when the battery reaches 2.9V.
