Micro Type-c USB 5V 1A TP4056 Lithium Battery Charger Module Charging Board With Protection Dual Functions Current Protection

描述

Product parameters

1. Input voltage: DC4.5V-5.5V; IN+IN pad wiring or MicroUSB 5V input;

2. Full charge voltage: DC4.2V;

3. Charging current: 1A adjustable;

4. Equipped with a charging indicator light;

5. Working temperature: -10 ℃~+85 ℃

Instructions for use

After power on, the blue indicator light of the module stays on, and the red indicator light flashes slightly;

When the battery is fully charged, the red and blue indicator lights of the module remain on;

be careful:

1. The wiring should distinguish between positive and negative poles, and reverse connect the burnt IC;

2. Charging requires short and thick wires to connect. If the wires are too thin or too long, the connection resistance will be high, and after charging, the battery voltage will drop more;

3. Connect the wires well, otherwise the battery voltage will drop more after charging is completed;

4. The output current can be adjusted by changing the fixed resistor in the circuit board to change the output current from 100mA to 1000mA;

If the 5V input voltage is too high, such as 5.2V or 5.5V, it will cause the charging current to be less than 1000mA, which is normal. When the voltage is high and the chip heats up, it will automatically reduce the charging current and lower the chance of the chip being burned;

6. If the charging current is too high or used in a high-temperature environment, heat dissipation treatment is required;

7. The ammeter for testing current can only be connected in series with the 5V input terminal of the charging board;

8. The satisfactory charging current should be 0.37 times the battery capacity. For example, a charging current of 400mA for a 1000mAh battery is sufficient;

9. If the charging speed is fast, the charging effect will be poor, and the more the battery voltage drops after charging is completed;

Product Introduction:

1. Input voltage: DC 5V;

2. Charging cut-off voltage: 4.2V ± 1%;

3. Maximum charging current: 1000mA;

4. Battery over discharge protection voltage: 2.5V;

5. Battery overcurrent protection current: 3A;

6. The input terminal is equipped with a MICRO USB socket, which can be directly used as an input power source to charge the lithium battery with a mobile phone charger;

usage method:

1. The MICRO USB socket and its adjacent+- pads are the power input terminals, with B+connected to the positive pole of the lithium battery and B – connected to the negative pole of the lithium battery. OUT+and OUT – can be connected to loads, such as the positive and negative poles of a mobile boost board or other loads.

2. Connect the battery to B+B -, insert the phone charging cable into the USB socket, the red light is on to indicate charging, and the blue light is on to indicate full charge.

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

be careful:

When connecting the battery for the first time, there may be no voltage output between OUT+and OUT -. In this case, charging the module with DC 5V voltage can activate the protection circuit. If the battery is disconnected from B+B – and reconnected, it also needs to be charged to activate the protection circuit. When using a mobile phone charger as an input power source, it is important to note that the charger and charging cable must be able to support a current output of 1A, otherwise it may cause the module to not charge the battery properly;

When charging the battery, the load on the OUT terminal should be disconnected, and the positive and negative poles should not be connected incorrectly. Please use according to the specifications, otherwise the module will be damaged.
