Description
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.
