Module features and parameters
Input voltage: 5V
Charging cut-off voltage: 4.2V min 1%
Maximum charging current: 1000mA
Battery over discharge protection voltage: 2.5V
Battery overcurrent protection current:3A
Board size:2.6*1.7CM
Can be used for voltage 3.6 3.7V 18650, polymer lithium batteries such as charge and discharge protection, single or multiple parallel can also be used
Use method:
Note: The first time you access the battery, there may be no voltage output between OUT+ and IOUT-, then access the 5V voltage charge can activate the protection circuit.
Battery from the B + B- on the short open and then connected to also need to charge a little to activate the protection circuit.
When using a cell phone charger to do the input, note that the charger must be able to output 1A or more, otherwise it may not be able to charge properly
MINI USB female chassis and the +- pad next to the power input, access to 5V. B + connect the positive terminal of the lithium battery, B - connect the negative terminal of the anal battery.
OUT+ and OUT- connected to the load, such as connecting the positive and negative terminals of the mobile boost board or other loads.
Connect the battery to B+ B-, insert the phone charger to the USB female socket, the red light is charging, the green light is full.
Module application range:
This module is used to charge single lithium battery or multiple lithium batteries in parallel, the charging port can take power from USB.
Instructions for use / Notes:
1. The ammeter for testing current can only be connected in series to the 5V input of the charging board.
2. The charging current is preferably 0.37C of the battery capacity, that is, 0.37 times the capacity, for example, 1000mAH battery charging current 400 so it is enough. Too large charging speed fast effect is poor, after charging the battery voltage off more!
3. charging connection wire can not be too thin and too long. This connection resistance is large. Too thin, then the battery voltage will fall off more. 4. and the battery connection is best contact good. Otherwise, the battery voltage will fall off more after charging.
5. If the 5V input voltage is high, such as 5.2 or even 5.5, will cause the charging current is less than 1000mA, which is normal. High voltage chip heating will automatically reduce the charging current, not to the chip burned. Chip in the work of about 60 degrees heat is normal. After all, the charging current is high.
6. input reverse connection on the chip does not affect, but the output (battery side) reverse connection will burn the chip, please pay attention to buyers.

Type-C interface:
Product parameters:
Input voltage: DC4.5V - 5.5V;
IN+ IN- pad wiring or Type-C 5V input;
Charging as of voltage: DC4.2V;
Charging current: 1A adjustable;
with charging indicator;
Operating temperature: -10°C to +85°C;
Instructions for use:
1. Pay attention to the wiring according to the diagram, do not connect the wrong.
2. This document only represents the editor's knowledge and parameters of the product at the time, and any later changes without notice.
3. charging needs to be connected with a short and thick wire, too thin and too long, the connection resistance is large, after charging, the battery voltage dropped more.
4. Connect the wires, need to contact well, otherwise after charging, the battery voltage will drop more;
5. If the 5V input voltage is high, such as 5.2V or 5.5V, it will cause the charging current to be less than 1000mA, which is normal. High voltage chip heating, will automatically reduce the charging current, reducing the chances of the chip being burned.
6. Charging current is too large, or in a high temperature environment, the need to do heat dissipation treatment.
7. The ammeter for testing current can only be connected in series with the 5V input of the charging board.
8. The satisfactory effect of charging current should be 0.37 times of the battery capacity. For example, 1000mAH battery charging current 400mA is fine.
9. The charging speed is fast, the charging effect is poor, and the more the battery voltage drops after charging is completed.

After power-up, the module's blue indicator light is always on and the red indicator light is faintly flashing;
When fully charged to the battery, the module's blue indicator light is always on;
Description of current adjustment:
Output current can be adjusted by itself, change the fixed resistor in the circuit board, you can change the output current of 100mA ~ 1000mA
