• RC airplanes and drones
• Robotics and other high-power applications
• Backup power for BEC (Battery Eliminator Circuit) systems

The following table outlines the key technical specifications of the Nano-Tech 3000 mAh 2S 20-40C Lipo Battery Pack:

The Nano-Tech 3000 mAh 2S battery pack includes two primary connectors:

1. Connecting the Battery:

   • Connect the BEC connector to the power input of your RC receiver or device.
   • Ensure the polarity matches the input terminals to avoid damage.
   • Use the balance connector with a compatible LiPo charger to ensure safe and balanced charging.

2. Charging the Battery:

   • Use a LiPo-compatible charger with a balance charging feature.
   • Set the charger to 2S (7.4V) mode and a charging current of 1C (3A).
   • Always monitor the charging process and avoid overcharging or overheating.

3. Discharging the Battery:

   • Do not exceed the maximum continuous current of 60A or the burst current of 120A.
   • Avoid discharging the battery below 3.0V per cell (6.0V total) to prevent damage.

• Storage: Store the battery at a voltage of 3.7-3.8V per cell (7.4-7.6V total) when not in use for extended periods.
• Temperature: Operate the battery within a temperature range of 0°C to 40°C. Avoid exposing it to extreme heat or cold.
• Safety: Never puncture, short-circuit, or expose the battery to water. Use a LiPo-safe bag for charging and storage.
• Inspection: Regularly inspect the battery for swelling, damage, or wear. Replace if any issues are detected.

The Nano-Tech 3000 mAh 2S battery can be used to power an Arduino UNO via its VIN pin. Below is an example:

/* Example: Powering an Arduino UNO with the Nano-Tech 3000 mAh 2S Battery
   Ensure the battery voltage is within the Arduino's input range (7-12V).
   Use a voltage regulator if necessary to avoid overvoltage. */

void setup() {
  // Initialize serial communication for debugging
  Serial.begin(9600);
  Serial.println("Arduino powered by Nano-Tech 3000 mAh 2S Battery");
}

void loop() {
  // Example: Blink an LED connected to pin 13
  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. Battery Not Charging:

   • Cause: Incorrect charger settings or damaged balance connector.
   • Solution: Verify the charger is set to 2S mode (7.4V) and inspect the connectors for damage.

2. Swollen Battery:

   • Cause: Overcharging, over-discharging, or overheating.
   • Solution: Discontinue use immediately and dispose of the battery safely.

3. Shortened Battery Life:

   • Cause: Frequent deep discharges or improper storage.
   • Solution: Avoid discharging below 3.0V per cell and store at 3.7-3.8V per cell.

4. Device Not Powering On:

   • Cause: Incorrect connection or insufficient charge.
   • Solution: Check the polarity of the BEC connector and ensure the battery is fully charged.

• Q: Can I use this battery for devices other than RC models?

  • A: Yes, as long as the device operates within the battery's voltage and current limits.

• Q: How do I safely dispose of a damaged battery?

  • A: Discharge the battery completely, submerge it in saltwater for 24 hours, and dispose of it at a designated recycling facility.

• Q: What is the maximum runtime I can expect?

  • A: Runtime depends on the load. For example, at a 10A load, the battery can last approximately 18 minutes (3000 mAh ÷ 10A).

By following these guidelines, you can ensure safe and efficient use of the Nano-Tech 3000 mAh 2S 20-40C Lipo Battery Pack.
