This Charge Module with Linear Charging is a reliable solution for charging applications, providing users with adjustable current settings and clear visual indicators for monitoring the charging process.

Specifications:

• Charge Module: Linear charging type.
• Current: 1A adjustable, allowing users to customize the charging current based on their requirements.
• Charge Precision: 1.5%, ensuring accurate and reliable charging for batteries.
• Input Voltage: 4.5V-5.5V, providing flexibility for various power sources within the specified range.
• Full Charge Voltage: 4.2V, preventing overcharging and ensuring the longevity of the connected battery.
• LED Indicator: Red LED indicates charging, while green LED signals a fully charged status, providing visual cues for the user.
• Input Interface: Micro USB, a commonly used and versatile connection for easy integration with various devices.
• Inversed Polarity: NO, meaning there is no protection against reversed polarity, so it is crucial to ensure correct connections during installation.
• Size: 25X19X10mm, offering a compact form factor suitable for space-constrained applications.

Note:

1. Ampere Meter Connection: Connect the ampere meter only to the 5V input end of the module.
2. Optimal Charging Current: It is recommended to set the charging current at 37% of the battery capacity. For instance, if charging a 1000mAh battery, a current of 400 is sufficient for efficient charging.
3. Wire Thickness: The connection wire should not be excessively thick to maintain proper functionality.
4. Connection Point: Ensure a good connection point to guarantee effective charging.
5. High Input Voltage Protection: If the input voltage exceeds 5.2V (e.g., 5.2v), the charging current will automatically decrease to less than 1000mA. This is a protective function to prevent chip damage due to excessive voltage.
6. No Inversed Polarity Protection: The module lacks protection against inversed polarity, emphasizing the need for careful and correct wiring to prevent damage.

Package Includes:

• 1 x DC-DC Battery charger for Lithium 18650 Li-ion charging Protection Board 5V 1A TP4056
