5 PCS Type C Mini Micro USB TP4056 5V 1A Charger Board Lithium 18650 Li-ion Battery Protection Charging Module Dual Functions |

Features

1、Charging protection to prevent the battery from overcharging and over-discharging, and automatically control the charging current to better protect the battery;

2、The type-c, micro and mini ports retain input voltage welding circuit, which is convenient for DIY.

Type C

1. Import voltage: 4.5V-5V IN + IN-Burning tangent or TYPE-C 5V import
2. Maximum charging current: 1000Ma
3. Charging to voltage: 4.2V ± 1%
4. Battery over-release voltage: 2.5V / 3A
5. Working temperature: -10 ℃ ~ + 85 ℃

The type-c female base and the +-pad next to it are the power input terminals, which are connected to the 5V input voltage. B+ is connected to the positive electrode of the lithium battery, and B- is connected to the negative electrode of the lithium battery. OUT+ OUT- is connected to a load, such as a booster board. Connect the battery to B+ B-, insert the mobile phone charger to the USB, the blue light is on, indicating that the power is connected, and the red light is flashing, indicating that it is charging. After the charge is full, the red light stops flashing and turns to a steady light.

A load can be connected to the OUT+ OUT- terminal. After the load is connected, the red light is always on. When there is power at the input terminal, the current is obtained from the output terminal of the power supply. If the power is not connected, the current is obtained from the battery. When the battery voltage is lower than 2.5V, the output is automatically turned off.

Micro USB

1. Import voltage: DC 5V; IN + IN-Burning tangent or Micro USB 5V import
2. Charging / stopping voltage: 4.2V ± 1%
3. Maximum charging current: 1000mA
4. Battery over-release voltage: 2.5V
5. Battery overflow protection current: 3A
6. Imported end battery MICRO USB mother seat, can direct handheld charger Next work import Imported power source Lithium battery charger
7. Working temperature: -10 ℃ ~ + 85 ℃

Instructions:
1. The MICRO USB socket and the +-pad next to it are the power input terminals, B+ is connected to the positive electrode of the lithium battery, and B- is connected to the negative electrode of the lithium battery. OUT+ and OUT- are connected to the load, and can be connected to the positive and negative poles of the mobile booster board or other loads.

2. Connect the battery to B+ B-, insert the mobile phone charging cable to the USB socket, the red light is on, it means charging, and the blue light is on, it means full.

Application: It can be used for charging and discharging protection of 18650 lithium batteries such as 3.6V 3.7V, polymer and other lithium batteries. Single or multiple batteries can also be used in parallel.

Mini USB

1. Import voltage: DC4.5V-5.5V; IN + IN-flame tangent or MiniUSB 5V import
2. Charge and compression: DC4.2V
3. Charging current: 1000mA
4. Charge indicator light
5. Working temperature: -10 ℃ ~ + 85 ℃

Instructions for use

1. After power on, the blue indicator light of the module is always on, and the red indicator light flashes slightly;
2. When the battery is fully charged, the red and blue indicator lights of the module are always
Special Note

1. Wiring needs to distinguish between positive and negative poles, and reverse connection to burn IC;
2. Charging needs to be connected with a short and thick wire. If it is too thin or too long, the connection resistance will be large. After the charging is completed, the battery voltage will drop more;
3. Connect the wires with good contact, otherwise the battery voltage will drop more after the charging is completed;
4. The output current can be adjusted by itself, changing the fixed resistance in the circuit board can change the output current of 100mA~1000mA;
5. If the 5V input voltage is too high, such as 5.2V or 5.5V, the charging current will be less than 1000mA, which is normal. When the voltage is high, the chip generates heat, which will automatically reduce the charging current and reduce the probability of the chip being burned;
6. If the charging current is too large, or it is used in a high temperature environment, heat dissipation is required;
7. The ammeter for testing current can only be connected in series to the 5V input terminal of the charging board;
8. The satisfactory effect of charging current should be 0.37 times of battery capacity. For example, a 1000mAH battery charging current of 400mA is sufficient;
9. If the charging speed is fast, the charging effect will be poor. After the charging is completed, the battery voltage will drop more;
