Product Details
1: Suitable for solar power generation system
2: Constant current/constant voltage operation, with thermal regulation function, which can maximize the charging rate without the risk of overheating
3: Automatically low power consumption when the input power supply voltage is removed. Power consumption sleep mode
4: Battery overvoltage protection
5: Wiring is simple and easy to understand
6: Two options, no needle and with needle. It is convenient for customers. If there is no special welding tool, choose with pin. If you want to change the pin direction, choose without pin. Product name: MPPT solar controller 3.7V 4.2V 18650 lithium battery charging 1A charger module
Power supply voltage DC 4.4-6V, charging output voltage DC 4.2V;
The 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 power supply
Suitable for solar power supply system
Pre-charge adjustment for recovering deeply discharged batteries and minimizing heat dissipation in the initial stage of charging
Constant current/constant voltage operation with thermal regulation function can maximize the charging rate without the risk of overheating
Automatic low-power sleep mode when the input power supply voltage is removed
C/10 charge termination
Automatic recharge
Battery overvoltage protection
LED indicator: ``CR'' LED is the charging status indicator
''OK'' LED is fully charged or constant voltage mode;
Working environment temperature -40℃～＋85℃
Size 18mm x 10.16mm x 2.7mm
Weight: 0.9g (with needle), 0.6g (without needle)
The on-chip adaptive battery can automatically adjust the charging current according to the output capacity of the input power source. Therefore, the SD05CRMA is very suitable for solar power systems or applications that need to charge lithium-ion batteries or lithium-polymer batteries. Input power with limited output capacity.
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.
1PCS 1A 5V MPPT solar controller for 3.7V 4.2V lithium ion and lithium polymer batteries
