TP4056 Battery Charging Protection Module (Type C)

TP4056 Battery Charging Protection Module

The TP4056 1A Li-Ion Battery Charging Board with Type-C and Current Protection is a compact and efficient charging module designed for single-cell 3.7V lithium-ion (Li-Ion) batteries, such as 16550 cells, that lack their own built-in protection circuit. Powered by the TP4056 charging IC and the DW01 battery protection IC, this module provides a 1A charging current and automatically stops charging once the battery is fully charged.

The module also features built-in protection to safeguard the battery. If the voltage drops below 2.4V, the protection IC disconnects the load to prevent over-discharging. Additionally, the protection circuit guards against over-voltage and reverse polarity connections. In the event of incorrect wiring, the module typically sacrifices itself to protect the battery. However, always double-check your connections before use to ensure safe operation.

Using the module:

1. Connect Type C cable for power, or 5V DC to pads marked IN+ and IN- on the left-hand side of the module
2. Connect cell to charge to B+/B- pads on the right-hand side of the module.
3. A load (something for the battery to power) can be connected to the OUT+/OUT- pads on the right-hand side
4. Important! Disconnect load when charging
5. The red LED indicates charging in progress, the green LED indicates charging has finished.
6. Never charge your battery at a rate greater than 1C.

NOTE:

1. Ampere meter can only be connected to a 5v input end of the module.

2. It is better than the charging current is 37% of the battery capacity. If you charge the battery of 1000mAh, a current of 400mAh is enough.

3. The connection wire should not be too thick.

4. Make sure the connect point is good.

5. If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-subtract the charging current to avoid burn damage to the chip.

6. NO Reverse polarity.

Features 

1. Led indicator: Red is charging Green is fully charged.
2. Current Protection: Yes
3. Inversed polarity: NO.
4. Use mature charging chip TP4056 for simple peripheral circuits, good protection performance, and high charging accuracy.
5. Fully machinery automated processing, all patch parts manufacturing.
