CD42 5V 2A Charge and Discharge Power Module, Integrated Boost Converter for 3.7V/4.2V Lithium Battery, DIY Power Bank & Charger Board

AYASOSO CD42 5V 2A 3.7V/4.2V Charge and Discharge Power Module, Integrated Boost Converter for Lithium Battery, DIY

This module can perform step-down charging and step-up discharging for single-cell lithium batteries, supporting simultaneous charging and discharging. It is suitable for use in lithium batteries without a protection board for protection and has 4 power indicator lights. Multiple protections and high reliability include output overcurrent, overvoltage, and short-circuit protection; input overvoltage, overcharge, over-discharge, and overcurrent discharge protection; and overall over-temperature protection. Parameter Introduction Module Type: Lithium Battery Charge/Discharge Protection Board Input Voltage: DC 4.5V-5.5V (DC 5V recommended) Charging Current: 0-2.1A Output Voltage: DC 5V (5.1V no-load output) Output Current: 2.4A max Module Interface: Pad (can also connect to 2.54mm header) Module Size: 25.4*16.0 (unit: mm) (Manual measurement, deviation may exist) When the module is properly connected to the lithium battery: (1) Input 5V charging, output no load: Module output is on. (2) No input power connected, output under load: When a load is connected to the output, the module will automatically turn on. The output voltage depends on the load; see the actual situation for details. Note: The module is always on. It will automatically turn on when a load is connected and will continue outputting continuously without being manually turned off.
