How to Use 18650 Lithium Battery Boost Module Type-C: Examples, Pinouts, and Specs

The 18650 Lithium Battery Boost Module Type-C (Manufacturer Part ID: ‎H-1-1790-2S1A) by Hailege is a compact and efficient power module designed to boost the voltage from a single 18650 lithium battery. It features a Type-C input for charging and power delivery, making it ideal for powering a wide range of electronic devices. This module is particularly useful in portable electronics, DIY projects, and battery-powered systems where a stable output voltage is required.

• Powering microcontrollers (e.g., Arduino, ESP32, Raspberry Pi Pico)
• Portable USB-powered devices
• DIY power banks
• Emergency backup power supplies
• Robotics and IoT projects

Below are the key technical details of the 18650 Lithium Battery Boost Module Type-C:

The module has the following key pins and connectors:

1. Connect the Battery:
   • Attach the positive terminal of the 18650 battery to the BAT+ pin.
   • Attach the negative terminal of the 18650 battery to the BAT- pin.
2. Connect the Load:
   • Connect the device or circuit requiring 5V power to the OUT+ and OUT- pins.
3. Charging the Battery:
   • Use a Type-C cable to connect a 5V power source to the module's Type-C port. The module will charge the 18650 battery while simultaneously providing power to the load.
4. Verify Connections:
   • Ensure all connections are secure and polarity is correct to avoid damage to the module or connected devices.

• Battery Selection: Use a high-quality 18650 lithium battery with a capacity of at least 2000mAh for optimal performance.
• Heat Management: Avoid overloading the module beyond its 1A output current limit to prevent overheating.
• Polarity Protection: Double-check the polarity of the battery and load connections to avoid damage.
• Charging Safety: Do not leave the module unattended while charging the battery to prevent overcharging or overheating.

The module can be used to power an Arduino UNO via its 5V pin. Below is an example setup:

1. Connect the OUT+ pin of the module to the 5V pin of the Arduino UNO.
2. Connect the OUT- pin of the module to the GND pin of the Arduino UNO.
3. Insert a charged 18650 battery into the module and ensure proper polarity.

Here is a simple Arduino sketch to blink an LED while powered by the module:

// Blink an LED connected to pin 13 of the Arduino UNO
void setup() {
  pinMode(13, OUTPUT); // Set pin 13 as an output
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}

1. Module Not Powering the Load:

   • Cause: Battery voltage is too low.
   • Solution: Recharge the 18650 battery using the Type-C port.

2. Overheating During Operation:

   • Cause: Load exceeds the 1A output current limit.
   • Solution: Reduce the load current or use a more efficient device.

3. Battery Not Charging:

   • Cause: Faulty Type-C cable or insufficient input voltage.
   • Solution: Use a high-quality Type-C cable and ensure the input voltage is 5V.

4. No Output Voltage:

   • Cause: Incorrect battery polarity or loose connections.
   • Solution: Verify the battery polarity and ensure all connections are secure.
