Input voltage : DC 7-28V
MPPT voltage :DC 7-25V(Adjustable)
Output voltage : 1.2-25V(Adjustable)
MPPT Disable: Solder J1 Pad
Charging current: 1A/2A/4A optional. You can also change the charging current by modifying the resistance of RCS1 and RCS2.
Can be used as Voltage Source when Battery is Absent
Automatic Conditioning of Deeply Discharged Batteries
Automatic Recharge
Led indicator : ''CR'' LED is charge status indicator(It may still be charging after the light goes out, this is normal)
Battery Overvoltage Protection
Operating Ambient Temperature－40℃ to ＋85℃
Size : 59 x 30 x 15mm
Weight : 16g(no Terminal);19g(with Terminal)
This is a step-down charging module with MTTP function. Please note when using it:
1 If the output fails after connecting to the power supply, please check whether the MTTP voltage is too high, and reduce the MTTP voltage
2 After the CR charging indicator is off, it is still charging, which is a normal phenomenon
3 The output current (charging current) is determined by the capacity and power of the battery. The maximum current cannot be directly output without connecting the battery.
4 This is a buck module, the input voltage must be more than 3V greater than the output voltage.

How to adjust parameters(18V solar panel, charge 12.8V LiFePO4 Battery):
1 BAT+/BAT- is connected to a 100-200Ω resistor, VIN/GND is connected to the output of the solar panel, and a multimeter is used to measure the BAT+/BAT- port voltage.
2 If there is no voltage output at the BAT+/BAT- port, turn the MPPT potentiometer clockwise until there is just voltage output.
3 If there is voltage output at the BAT+/BAT- port, rotate the MPPT potentiometer counterclockwise until there is just voltage output.
4 Rotate the VOUT potentiometer to make the output 12.8V
* 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.
