Power supply voltage DC 4.4-6V,Charging output voltage DC 4.2V;
The maximum charge current / output current is 1A, but you can change the current by changing the value of the R1 resistor.
Automatic charge current adjustment based on the output capability of input power supply
Suitable for Solar-Powered System
Precharge Conditioning for Reviving Deeply Discharged Cells and Minimizing Heat Dissipation During Initial Stage of Charge
Constant-Current/Constant-Voltage Operation with Thermal Regulation to Maximize Charge Rate Without Risk of Overheating
Automatic Low-Power Sleep Mode When Input Supply Voltage is Removed
C/10 Charge Termination
Automatic Recharge
Battery Overvoltage Protection
Led indicator : ''CR'' LED is charge status indicator
''OK'' LED is fully charged OR Constant voltage mode;
Operating Ambient Temperature－40℃ to ＋85℃
Size 18mm x 10.16mm x 2.7mm
Weight : 0.9g(With Pin),0.6g(No Pin)
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.
If your solar panel is larger than 5V(e.g. 6V 9V 12V 18V 24V 36V 48V), you can convert it to 5V with DC-DC buck module(e.g. DD2712SA_5V/DD8024TA_5V).
The charging current can be changed by changing the value of resistor R1
0805 1% SMD resistor is recommended
* Delivery Time.
We need 1-2 days to process your order before shipping.There are two shipping methoed. Fast Delivery: The delivery time for US, European countries the delivery will take 3-5 days.Slow Delivery: The delivery time for US, European countries the delivery will take 10-15 days.
* Tracking information.
After we ship package, customer receive automatic email with tracking details.
* Lost Package Policy.
If a package did not arrive in 4 weeks after the shipping date, then this package is treated as Lost. In this case a new package will be shipped to the customer provided we are able to give the same items as those purchased by the customer. If we are not able to provide the same items to substitute the lost ones we will either propose to the customer similar items or refund their cost as it will be mutually agree with the customer. If one or more items neither the same nor similar are available to be shipped, the customer can request to cancel the order entirely, thus the total cost of the order including shipping and handling cost will be fully refunded.
