Product Name:  2x 1A 4.2V 3.7V Li-ion Li-Po Lithium Battery Multifunction Charger MPPT Solar Controller Module for Solar panel mobile power USB
    
Packing list:
  
2 PCS 3.7V 4.2V Li-ion Li-Po Lithium Battery Charger Module 
 
 
 
 
Description: 
 
3.7V 4.2V Li-ion Li-Po Lithium Battery Charger Module with automatic current limiting function
     
Power supply voltage DC 4.4-6V(DC 5V),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

Weight : 0.9g(With Pin),0.6g(No Pin)
         
     
 If you need a chip brochure please contact me
      
     
The on-chip adaptive cell can adjust charging current automatically based on the output capability of input power supply, so SD05CRMA is ideally suited for the solar-powered systems, or the applications that need to charge lithium-ion battery or lithium polymer 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.
  
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

There are two purposes for connecting the NO and NC ports of the relay:
The water pump is connected to the COM NC port to automatically fill the water tower
The water pump is connected to the COM NO port to automatically pump water from the water tower
Note:
1 Package does not contain probe (wire).2P Male XH2.54mm Pitch Wire Cable can be used as a probe,which can be purchased separately or prepared by yourself.
2 For safety, use an DC power supply with good isolation
 
 
Application
Home water tower automatic water supply system
Aquarium Fish tank Water Changer System
Fill the water tower automatically
Automatic pumping from water tower
Conductive liquid automatic control
Automatic feeding system for poultry and livestock
Farm automatic water supply system
And other occasions that require automatic water supply and water exchange.
Solenoid valve water pump motor automatic control
Interface description:
HIGH : Upper limit probe
LOW : Lower limit probe
DC : Power of positive
DC- : Power of negative
NC : Relay normally closed contact
COM : Relay common contact
NO : Relay normally open contact
Working principle(Fill the water tower automatically):
The water level rises: When the water level is lower than the ''Low level'', the water pump starts to supply water to the water tower; when the water level is higher than the ''High level'', the water pump stops supplying water.
Water level reduction: When the water level is lower than the ''High level'', the water pump does not work and the water level continues to decrease. When the water level is lower than the ''Low water level'', the water pump starts to supply water to the water tower.
Working principle(Automatic pumping from water tower):
Contrary to ''Fill the water tower automatically''
Make the probe(Need to be purchased separately):
1 Prepare 2PCS(or more) XH2.54MM wires
(You can prepare this kind of wire by yourself, or buy it from our shop)
2 Multiple wires can be spliced to lengthen the probe length.
(Please do waterproof treatment at the splicing.)
3 Please cut the female interface short and keep a distance of 5-10MM
(This prevents water droplets from sticking to the probe. )

7 Size: 43mm X 21mm X 16mm
8 Weight: 13.5 g
This is a bistable (self-locking) Reverse polarity relay module,Trigger once, Output reverse polarity (and holds);Trigger again,the output=input (and holds)
Pin description: 
I :Power Input ;
I-  :Power Input -;
O :Power Output (When reversed is Power Output -);
O- :Power Output -(When reversed is Power Output );
G:trigger signal input  ground;
T:trigger signal input terminal(0.2-2 second low pulse trigger).
Note:
1 For the module to work stably, be sure to use a power supply with sufficient current.Power supply current is greater than 2 times load current
2 The maximum load current is 2A, if it is a motor, the maximum load current is 1A
3 Can only control forward and reverse(Start and stop by power on and power off control)
How to use:
Power-on, the output=input, press the trigger button, Reverse polarity output, press again,  the output=input, the third press, Reverse polarity output, and so on.
Turn off the power and stop output

Note:
1 In order to obtain a more stable voltage, it is recommended that the output is greater than 15MA
2 V- cannot be used alone, or no voltage output.But you can just use V
3 The startup current of the module is 2.5-3 times the operating current.
4 Increasing the 1UF-10UF MLCC capacitor reduces the startup current(As shown below)
Applications
ADC/DAC/Operational Amplifier Reference voltage
RS232 RS485 RS422 Bus
Audio equipment
Low power audio power supply
Car audio amplifier dual power board

Instrumentation equipment
Instrumentation multimeter
Attention :
This is a DC-DC voltage converter module,Must be noted when using:
1 Input voltage can not be greater than the maximum input range
2 Output power can not be greater than the maximum load for a long time
3 Input power must be greater than the output power, because the power consumption of the module itself
Q & A:
Q1 : Why output voltage is less than the nominal voltage
A1: Input power supply power is too low.Test the input voltage with a multimeter,a t this time of the input voltage is very low
Q2 : Why is the negative voltage not output or the output too low?
A2 : The negative voltage cannot be used alone. When using a negative voltage, the same load must be connected at the positive voltage terminal.
The maximum output power can reach 20W, but the maximum power will vary under different conditions. For details, please refer to the following table(10-80% of the maximum power is the most reliable):
5V/±5V Output
6V/±6V Output
9V/±9V Output
10V/±10V Output
12V/±12V Output
15V/±15V Output
24V/±24V Output
