TP4056 Battery Charger C Type Module with Protection
The TP4056 Battery Charger C Type Module with Protection is a compact charging and battery protection board for single-cell 3.7V Li-ion and Li-Po batteries. It provides a convenient way to add rechargeable battery power to DIY electronics, robotics, IoT devices, portable gadgets and other low-power projects.
The module uses the TP4056 linear lithium-ion charging IC to charge a single cell using a constant-current/constant-voltage (CC/CV) charging method. With a charging current of up to 1A, it can provide a practical charging solution for compatible rechargeable cells. The charging voltage is fixed at 4.2V, making it suitable for standard 3.7V nominal Li-ion/Li-Po cells.
A built-in battery protection circuit helps protect the connected cell against overcharge, over-discharge and over-current conditions. The separate B+ and B− terminals are used for connecting the battery, while OUT+ and OUT− provide the protected output for a connected load. Power can be supplied through the convenient USB Type-C input or the IN+ and IN− solder pads.
Two onboard LEDs provide a quick charging-status indication: the red LED indicates charging, while the green LED indicates a completed charge. This makes the board easy to monitor without additional circuitry.
The TP4056 module is especially useful when building rechargeable battery-powered Arduino projects, ESP32 projects, portable electronics, sensor nodes, small IoT devices and DIY power systems where a simple single-cell charging and protection solution is required.
Important: This is a single-cell charger. Always verify battery polarity, battery chemistry and the required charging current before connecting a cell. Do not use it for multi-cell series battery packs.
Use the Module Through the Following Steps:
- To supply power, either plug in a Type C cable or attach a 5V DC source to the IN+ and IN-labeled pads on the module's left side.
- Fasten the battery that has to be charged to the B+/B- pads on the module's right side.
- The OUT+/OUT- pads on the right side can also be used to attach a load, or an object that the battery will power.
- Keep in mind that while the battery is charging, unplug the load.
- When the charging process is finished, the green LED will turn on, while the red
- LED will illuminate to signify that the charge is ongoing.
- Be careful to never charge your battery at a rate exceeding 1C
Note:
Please remember the following crucial information:
- The module's 5V input side is the only one to which the ampere meter should be attached.
- A charging current of around 37% of the battery's capacity is advised.
- A 400mAh charging current is adequate for a 1000mAh battery.
- Make use of reasonably thin connecting cables.
- Verify the security of the connecting point.
- It is usual for the current to decrease below 1000mA if the input voltage is greater
- than 5.2V.
- In order to shield the chip from harm, this protective function immediately lowers
- the charging current.
- Reverse polarity should be avoided at all costs.
