5pc TP4056 5V 1A Type-C Micro USB 18650 Lithium Battery Charging Protect Board

10/08/2026

5pc TP4056 5V 1A Type-C Micro USB 18650 Lithium Battery Charging Protect Board Description: This enhanced module is designed for charging lithium batteries, specifically 18650 cells and other 3.6/3.76V lithium cells, using the constant-current/constant-voltage (CC/CV) method. It’s equipped with the TP4056 chip, offering efficient and safe charging. Key Features: Input Voltage: 4.5-5.5V Input Interface: Dual options with Micro-USB and Type-C USB, along with solder pads for DIY projects. Output Current: 1A; with a full charge output voltage of 4.2V. Size: Compact dimensions of 25x19x6mm for the Micro-USB version, and 26x17mm for the Type-C version. Indicators: Red light for charging and green light when fully charged. Safety and Efficiency: Overcharge Protection: If the input voltage exceeds 5V (up to 5.5V), the charging current is reduced to prevent overheating. Dual Function: The board both charges the lithium cells and protects them from over-discharge and over-current. Discharge Protection: Cuts off at 2.5V to prevent battery damage. Over-Current Protection: Features a 3A cut-off for safety. Short-Circuit Protection: Automatically cuts off in the event of a short circuit. Usage and Applications: Charging: Connect the battery to B+ and B- terminals, and power the module via the Micro-USB or Type-C input for charging. Discharge Protection: Features a DW01A protection IC that disconnects the battery below 2.4V to prevent over-discharging. Trickle Charge Feature: When the battery voltage is below 2.9V, the module trickle charges the battery, then gradually increases the current up to 1A. Compatibility: Ideal for single cell 3.7V LiPo cells such as 16550s and 18650s. Can charge two cells in parallel, but the charging time doubles. Note: The USB port is exclusively for charging. This module is suitable for those with a basic understanding of electronic components. Package Contents: 5x TP4056 5V 1A Lithium Battery Charging Protect Boards with either Micro USB or Type-C inputs.

2pcs TP4056 5V 1A Micro USB 18650 Lithium Battery Charging and Protection Board

10/08/2026

Dual Function: 1) Charge lithium cells from a 5V power source 2) Protect battery from over-discharge and over-currentCharge input: 5V DC • Maximum charge current: 1000mA • Charge cut-off: 4.2VDischarge protection cut-off: 2.5V • Over-current protection cut-off: 3AMicro-USB input • Size: 2.6×1.7cmThis is an enhanced USB-powered module for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method.This module provides constant-current/constant-voltage (CC/CV) charging, along with protection against over-voltage, over-discharge, over-current and short circuits to protect the battery and the device that it is powering.The device to be powered by the battery is connected to the module’s OUT+ and OUT- connectors and the battery is connected to the B+ and B- connections. When connected to USB power, the module provides up to 1A charge current until the battery is charged, then switches to a constant voltage mode to keep it charged.During use, if the battery voltage drops below about 2.4V, the DW01A protection IC disconnects the battery from the OUT connectors, disabling discharge to protect the battery from running at too low and self-destructing.When the module is then connected to USB power, it will trickle charge the battery to 2.9V (the over-discharge release voltage), at which point the charge current will be linearly increased to 1A maximum and the module will reconnect the battery to the OUT connections, allowing discharge of power from the battery to a connected load. Although the module cuts output power from the battery during an over-discharge situation, it still allows trickle charging of the battery to occur.The module also protects against overcurrent and short-circuit protection – it will cut the output from the battery if the discharge rate exceeds 3A or if a short-circuit condition occurs.This module is perfect for charging single cell 3.7V 1 Ah or higher LiPo cells such as 16550s and 18650s that don’t have their own protection circuit. It can charge two cells in parallel, however since the two cells share the charging current, they take twice as long to charge as a single cell.
