TP4056 TC4056 1A Lipo Battery Charging Board Type C USB

The TP4056 TC4056 1A Lipo battery charging board is a small charger for single-cell 3.7 V lithium-ion and lithium-polymer batteries, such as 18650 cells and LiPo packs. It takes 5 V from a USB Type-C cable and charges the battery with the standard constant-current / constant-voltage method up to 4.2 V, at a charge current of up to 1 A. Two LEDs show when the battery is charging and when it is full.

TP4056 Charging Board Specifications

• Charger IC: TP4056 / TC4056 linear Li-ion charger

TP4056 Charging Board Applications

• Charging 18650 cells and LiPo packs in DIY power banks
• Adding USB-C charging to ESP32, Arduino and sensor projects
• Portable lights, speakers and handheld devices
• Robotics and STEM kits that run on a single Li-ion cell

What's in the Box

• 1 × TP4056 Type-C 1 A charging board

Tip: Charge only one cell at a time and check the polarity before connecting it to B+ and B−. If the board has only B+ and B− pads and no OUT+ / OUT− pads, it has no battery protection, so use a protected cell or add a protection circuit. For small batteries under 1000 mAh, lower the charge current by changing the programming resistor.
