TP4056 1A Lipo Battery Charging Board Micro USB

The TP4056 1A Lipo Battery Charging Board is a small charger module for single-cell 3.7 V lithium batteries, including LiPo pouch cells and 18650 Li-ion cells. Plug a 5 V supply into the micro USB port and it charges the cell with a constant-current, constant-voltage profile up to 4.2 V, with LEDs showing when charging is in progress and when it is complete.

TP4056 1A Lipo Battery Charging Board Applications

• Rechargeable power for ESP32, ESP8266 and Arduino projects
• DIY power banks with 18650 cells
• Portable sensors, lights and gadgets
• Replacing chargers in small battery-powered devices

What's in the Box

• 1 × TP4056 1 A LiPo charging board, micro USB

Tip: Use this board for one cell only, never for 2S packs. The default 1 A current suits 18650 cells; for small LiPo batteries under 1000 mAh, replace the RPROG resistor to lower the current, for example 2 kΩ for about 580 mA.
