MPPT Solar Charge Controller 4.2V 3.7V 18650 Lithium Battery Charger Module with Protection Function SD05CRMA

1. battery charger for solar powered system. supply voltage DC 4.4-6V charging output voltage DC 4.2V. 2. Maximum charging current/output current is 1A but you can change the current by changing the value of the R1 resistor. Automatically adjust the charging current according to the output capacity of the input supply. 3. Precharge adjustment for restoring deep discharge batteries and minimize heat dissipation at the initial charging stage. current/ voltage operation with thermal regulation maximizes charging rate without overheating . 4. Automatic low sleep mode when the input voltage is removed. C/10 charge termination. 5. Automatic recharge. Battery overvoltage protection. Item Type: Battery Solar Charge Module LED Indicator: CR LED is charge status indicator; OK LED is charged OR voltage mode Instruction: The adaptive unit on the module can adjust charging current automatically based on the output capability of input supply so it is for the solar-powered systems or the applications that need to charge -ion battery or battery with an input 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 supply.
