USB-C TP4057 1A Lithium Battery Charging Protection Board
The USB-C TP4057 1A Lithium Battery Charging Protection Board is an advanced and versatile solution for safe and efficient charging and discharging of single 3.7V lithium-ion batteries (supports multiple parallel cells). Featuring the TP4057 chipset, this board supports both charging and discharging functions, offering a dual-purpose design for easy integration into various DIY projects and low-power electrical equipment.
With a Type-C USB input, this board provides a convenient and reliable power source for your lithium battery. It uses constant current/constant voltage charging with over-temperature protection to ensure the safety and longevity of the battery. The board also prevents reverse battery connection, overcharging, and overdischarging, further enhancing its reliability.
The charging process is straightforward and efficient, with LED indicators showing red during charging and blue when the battery is fully charged. This module supports a wide input voltage range of 4.2V to 6.5V and operates efficiently in temperatures between -40°C to 80°C.
The board features a soft start function to limit surge currents and uses low power standby mode to extend battery life. It also supports 0V to 2.9V activation, making it suitable for deeply discharged batteries. The board can charge batteries in parallel configurations (not in series), ensuring versatility for a range of applications, including backup power circuits, low-power devices, and DIY projects.
