5 Pack 5V 1A Type-C Charge Discharge Protection Module

Cermant 5 Pack Type-C 5V 1A Charge and Discharge Module for 3.7V Rechargeable Energy Storage Cells This compact module supports charging single-cell 3.7V rechargeable energy storage cells and provides stable 5V power output. It automatically switches between charging and power output modes, which is perfect for DIY circuit production, portable electronic equipment, standby power refitting and electronic experiment projects. Main Features Type-C USB input interface Matches single-cell 3.7V rechargeable energy storage cells Input voltage: 4.5V-5.5V Recommended input voltage: 5V Maximum charging current: 1A under normal working conditions Charging stop voltage: 4.2V Low voltage protection value: approx 2.9V Automatic switching between charging and output Small circuit board for miniature DIY equipment installation How It Works The module will start energy storage automatically once external power is connected. After disconnecting the external power supply, it will turn to power output mode immediately. This structure simplifies the wiring of small power supply systems and avoids manual mode adjustment. Status Indication Onboard LED lights display the working state. The charging light blinks during energy storage and remains steady when fully charged. The blue light stays on when the module supplies power to external loads. Application Scenarios Suitable for DIY power supply production, small standby power circuits, portable equipment refitting, mini power supply systems, electronic teaching experiments and low-power electronic equipment. Important Notes Only fit for single-cell 3.7V rechargeable energy storage units Parallel connection is allowed with proper operation; series connection is not available Actual output effect is affected by cell condition, load and wiring Energy storage cells are not contained in the package Package Includes 5 x Type-C 5V 1A Charge and Discharge Modules

• COMPACT TYPE-C CHARGING BOARD This compact charge and discharge circuit board works with single-cell 3.7V rechargeable energy storage cells. The Type-C input port simplifies wiring work for handmade circuits, standby power supply and small low-power portable equipment.
• STABLE CHARGE & DISCHARGE PARAMETERS Input voltage range: 4.5V-5.5V, 5V power supply is recommended. The charging process will stop automatically at 4.2V, and the low-voltage cut-off point is set at roughly 2.9V. The maximum charging current can reach 1A under standard conditions, and it maintains steady 5V output during power release.
• AUTOMATIC MODE SWITCHING This circuit can shift between charging and power output automatically. It stores energy when external power is connected. Once the power supply is disconnected, it immediately switches to output mode without manual adjustment for your handmade projects.
• WIDE DIY APPLICATION Perfect for homemade standby power units, portable equipment modification, small power source assembly and various low-voltage electronic equipment. Ideal for electronic maintenance workers and electronics enthusiasts.
• PACKAGE CONTENTS You will receive 5 pieces of Type-C charge and discharge circuit boards. Suitable for repeated testing, spare part replacement, laboratory inventory, teaching practice and multiple project assembly.
