安全情報
- Always ensure correct polarity when connecting batteries to avoid damage to the module or battery.
- Do not short-circuit the battery terminals or the module's input/output.
- Use within the specified input voltage range (DC 3-6V). Exceeding this may damage the module.
- Ensure adequate ventilation during operation, especially when charging at higher currents.
- This module is designed for lithium-ion batteries. Do not use with other battery chemistries unless explicitly stated.
- For the 4A version (if applicable), ensure your power supply can provide the necessary current.
セットアップと接続
Follow these steps to set up and connect your AITIAO 2S 1A Boost Charging Module.
1. モジュールオーバーview

The module features a Type-C USB input port, battery connection pads (BAT and GND), and indicator LEDs ("CR" and "OK"). The bottom side indicates the version (2S, 3S, 4S) and current ratings (1A, 2A, 4A).
2. バッテリーの接続
- Connect the positive terminal of your 2-cell (8.4V) lithium-ion battery pack to the "BAT" pad on the module.
- Connect the negative terminal of your battery pack to the "GND" pad on the module.
- Ensure all connections are secure and correctly polarized. Incorrect wiring can damage the module and battery.

3. モジュールの電源供給
The module can be powered via its Type-C USB port or directly through the VIN and GND pads.
Using Type-C USB Input:
- Connect a standard USB-A to Type-C cable from a 5V power source (e.g., USB wall adapter, power bank) to the module's Type-C port.
- 重要： The module typically requires a 5V input. Some USB-C to USB-C cables may not trigger the necessary 5V power delivery (PD) from certain power sources, resulting in no power to the module. It is recommended to use a USB-A to USB-C cable for reliable operation.
- For higher current versions (e.g., 4A), ensure your Type-C power supply can provide the required current.

Using DC Power Supply Input:
- Alternatively, you can connect a DC power supply directly to the "VIN" (positive) and "GND" (negative) pads on the module.
- DC入力ボリュームを確認してくださいtageは3～6Vの範囲内です。
- For 2A/4A versions, provide a power supply capable of delivering greater than 2A/4A current respectively.

操作手順
Once the battery and power supply are correctly connected, the module will begin charging the battery.
- Charging Indicator ("CR" LED): This LED will illuminate when the battery is actively charging.
- Fully Charged Indicator ("OK" LED): This LED will illuminate when the battery is fully charged or when the module enters constant voltageモード。
- The module automatically manages the charging process, including over-voltage保護。
メンテナンス
- モジュールを清潔に保ち、ほこりや湿気を避けてください。
- モジュールを極端な温度や直射日光にさらさないでください。
- 接続部に摩耗や損傷の兆候がないか定期的に点検してください。
- Do not attempt to modify the module, as this may void any implied warranty and could lead to unsafe operation.
