Lithium Battery Charging Module 2 Pack TP4056 USB
TP4056 USB charging module for 3.7V lithium batteries. 1A adjustable current, LED indicator. Pack of 2. Ideal for DIY and Arduino.
The Lithium Battery Charging Module (2 Pack) from Whadda UK is a practical and reliable charging solution for single-cell lithium-ion batteries. Each module is based on the popular TP4056 chip, delivering constant current/constant voltage charging for safe and efficient power management.
This pack includes two compact modules, each featuring an onboard USB connector for easy power input. The modules accept a supply voltage of 4.5V to 5.5V and provide a default charging current of 1A, which is adjustable to suit your specific battery needs. The full charge voltage is precisely regulated at 4.2V, ensuring your batteries are charged to their optimal capacity without overcharging.
A built-in two-colour LED indicator keeps you informed of the charging status: a red LED signals charging in progress, while a green LED confirms a fully charged battery. This clear visual feedback makes it easy to monitor the charging cycle at a glance.
With compact dimensions of 10 x 19 x 25mm per module, these charging boards are ideal for DIY projects, retrofitting into battery-powered devices, or creating custom charging stations. The modules are compatible with Arduino and other microcontroller projects, making them a versatile addition to any electronics workbench.
