With a capacity of 3300 milliamp hours (mAh), this battery is ideal for powering remote-controlled (RC) vehicles, drones, and portable electronic devices. Its high energy density and discharge rate make it a popular choice for demanding applications where performance and reliability are critical.

• RC vehicles (cars, boats, planes)
• Drones and quadcopters
• Portable electronic devices
• Robotics and DIY electronics projects
• Backup power for small systems

The following table outlines the key technical details of the Pro Range Lipo 3300 mAh battery:

The Pro Range Lipo 3300 mAh battery typically includes two connectors: a main power connector and a balance connector. The pin configurations are as follows:

1. Connecting the Battery:

   • Use the XT60 connector to connect the battery to your device or power distribution board.
   • Ensure the polarity matches the device's input to avoid damage.
   • Use the JST-XH balance connector for charging or monitoring individual cell voltages.

2. Charging the Battery:

   • Use a LiPo-compatible charger with a balance charging feature.
   • Set the charger to the correct cell count (3S) and charge rate (recommended: 3.3A).
   • Connect both the XT60 and JST-XH connectors to the charger for safe and balanced charging.

3. Discharging the Battery:

   • Avoid discharging below 9.0V to prevent damage to the cells.
   • Monitor the voltage during use with a voltage alarm or telemetry system.

4. Mounting:

   • Secure the battery in your device using a Velcro strap or battery holder.
   • Avoid placing the battery near sharp edges, heat sources, or moving parts.

• Storage: Store the battery at 50% charge (approximately 11.4V) in a cool, dry place.
• Safety: Never puncture, crush, or short-circuit the battery. Use a LiPo-safe bag for charging and storage.
• Temperature: Operate the battery within the temperature range of 0°C to 50°C. Avoid overheating.
• Inspection: Regularly inspect the battery for swelling, damage, or loose connectors.

The Pro Range Lipo 3300 mAh can power an Arduino UNO via a voltage regulator or a DC-DC step-down converter. Below is an example of connecting the battery to an Arduino UNO:

• Connect the XT60 connector to a DC-DC step-down converter.
• Set the converter output to 5V.
• Connect the converter's output to the Arduino UNO's 5V and GND pins.

// Example code to read a sensor and send data via serial
// Ensure the Arduino is powered by the LiPo battery through a step-down converter

const int sensorPin = A0; // Analog pin connected to the sensor
int sensorValue = 0;      // Variable to store the sensor reading

void setup() {
  Serial.begin(9600); // Initialize serial communication at 9600 baud
}

void loop() {
  sensorValue = analogRead(sensorPin); // Read the sensor value
  Serial.print("Sensor Value: ");
  Serial.println(sensorValue); // Print the sensor value to the serial monitor
  delay(1000); // Wait for 1 second before the next reading
}

1. Battery Not Charging:

   • Cause: Incorrect charger settings or damaged balance connector.
   • Solution: Verify the charger is set to 3S mode and the correct charge rate. Inspect the connectors for damage.

2. Battery Swelling:

   • Cause: Overcharging, over-discharging, or overheating.
   • Solution: Stop using the battery immediately. Dispose of it safely following local regulations.

3. Device Shuts Down Prematurely:

   • Cause: Voltage drops below the device's cutoff threshold.
   • Solution: Ensure the battery is fully charged before use. Check for excessive current draw.

4. Battery Not Providing Enough Power:

   • Cause: Exceeding the battery's discharge rate.
   • Solution: Use a battery with a higher C-rating or reduce the load on the battery.

• Q: Can I charge the battery at a higher rate than 1C?
  A: Yes, the battery supports up to 2C (6.6A), but charging at 1C is recommended for longer lifespan.

• Q: How do I know when the battery is fully charged?
  A: The charger will indicate "fully charged" when the voltage reaches 12.6V.

• Q: Can I use this battery for a 12V system?
  A: Yes, but ensure the system can handle the voltage range of 9.0V to 12.6V.

• Q: What happens if I over-discharge the battery?
  A: Over-discharging can permanently damage the cells. Use a voltage alarm to prevent this.
