TP4056 Battery Charging Module With Current Protection – Type C

Description

How to Use the Module:

1. Connect a USB Type-C cable for power, or supply 5V DC to the pads labeled IN+ and IN- on the left side of the module.

2. Connect the battery to be charged to the B+ and B- pads on the right side.

3. Connect your load/device to the OUT+ and OUT- pads on the right side.

4. Important: Always disconnect the load while charging the battery.

5. The red LED indicates charging in progress; the green LED indicates charging complete.

6. Never charge a battery at a rate higher than 1C.

Notes
1. An ammeter can only be placed on the 5V input side of the module.

2. The recommended charging current is approximately 37% of the battery capacity.
Example: For a 1000 mAh battery, a charging current of ~400 mA is sufficient.

3. Avoid using overly thick wires for connections.

4. Ensure all connection points are clean and secure.

5. If the input voltage is slightly high (e.g., 5.2V), the charging current may drop below 1000 mA.

This is normal—it’s a protection feature that reduces current to prevent chip damage.

6. Do not reverse polarity on any connections.

Features:
1. LED Indicators:
Red: Charging
Green: Fully charged

2. Overcurrent protection: Yes

3. Reverse polarity protection: No

4. Uses the TP4056 charging IC for stable operation, high accuracy, and robust protection.

5. Manufactured using automated assembly with high-quality surface-mount components.
