USB-C Li-Pol Battery Charge Protection Board TP4056 1S 1A

USB Type C charger with a maximum power of 1A for lithium-ion batteries. It has work functions as a buffer power supply. This system will be useful when building additional power sources (e.g. power bank).

It has a protection that prevents the charging voltage from exceeding 4.2V, and also protects against excessive discharge - 2.5V (under load). This is important because Li-Ion, Li-Pol batteries can be damaged during overcharging and excessive discharge. 

The principle of operation is very simple: giving 5V INPUT power, the module charges the battery pack, and this voltage appears on the output of the OUT + and OUT- terminals. When this power supply is disconnected, the module provides battery power, thanks to which the powered receiver will receive electricity all the time.

Useful device especially when using alternative energy sources, e.g. photovoltaic panels or wind turbines.

Specification:

• 4.5-5.5V power supply (built-in USB C socket for powering the system) or connectors for soldering 4.5-5.5V power supply marked + -
• The voltage at terminals B + and B- is max 4.2V - one cell (1S)
• Charging voltage 4.2V +/- 1.5%
• Discharge threshold voltage: 3V +/- 1.5%
• Maximum current 1A - adjustable (R3)
• LED charging indicator red
• LED charge indicator blue
• Dimensions 18x27x4mm
• Protection against overcharging and excessive discharge
• B +, B- leads are used to connect the Li-Ion - Li-Pol cell
• OUT + terminals - are used to connect a device powered from the cell
