How to Use Lipo 3300 mAh: Examples, Pinouts, and Specs

The Pro Range Lipo 3300 mAh is a high-performance lithium polymer (LiPo) battery designed for applications requiring lightweight, compact, and high-capacity power sources. 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 capabilities make it a popular choice for demanding applications.

• RC vehicles (cars, boats, planes)
• Drones and quadcopters
• Portable electronics (e.g., handheld devices, DIY projects)
• Robotics and automation systems
• Backup power for small devices

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

The Pro Range Lipo 3300 mAh battery includes two connectors: a power connector and a balancing connector. The pin configuration for the balancing connector (JST-XH) is as follows:

1. Connect the Power Connector: Use the XT60 connector to connect the battery to your device or power distribution board. Ensure the polarity matches (yellow for positive, black for negative).
2. Use a Balancing Charger: Always charge the battery using a LiPo-compatible balancing charger to ensure all cells are charged evenly.
3. Monitor Voltage Levels: Avoid discharging the battery below 3.0V per cell (9.0V for a 3S battery) to prevent damage.
4. Secure the Battery: Use straps or holders to secure the battery in place during operation, especially in RC vehicles or drones.

• Charging: Use a charger with a maximum charge rate of 5C (16.5A for this battery). Set the charger to 11.1V (3S) mode.
• Storage: Store the battery at 50% charge (approximately 3.8V per cell) in a cool, dry place to prolong its lifespan.
• Safety: Never puncture, short-circuit, or expose the battery to fire or water. Always handle with care.
• Temperature Monitoring: Avoid using the battery if it becomes excessively hot during operation or charging.

To power an Arduino UNO with the Lipo 3300 mAh battery, you can use a voltage regulator or a DC-DC step-down converter to step down the 11.1V to 5V. Below is an example circuit and code:

1. Connect the XT60 connector to a DC-DC step-down converter.
2. Set the output voltage of the converter to 5V.
3. Connect the output of the converter to the Arduino UNO's 5V and GND pins.

// Example code to read battery voltage using Arduino UNO
// Ensure a voltage divider is used to step down the battery voltage
// to a safe level for the Arduino's analog input (max 5V).

const int batteryPin = A0; // Analog pin connected to the voltage divider
const float voltageDividerRatio = 5.7; // Adjust based on your resistor values

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

void loop() {
  int rawValue = analogRead(batteryPin); // Read the analog input
  float batteryVoltage = (rawValue / 1023.0) * 5.0 * voltageDividerRatio;
  
  // Print the battery voltage to the Serial Monitor
  Serial.print("Battery Voltage: ");
  Serial.print(batteryVoltage);
  Serial.println(" V");
  
  delay(1000); // Wait for 1 second before the next reading
}

1. Battery Not Charging

   • Cause: Incorrect charger settings or damaged balancing connector.
   • Solution: Verify the charger is set to 11.1V (3S) mode and check the balancing connector for damage.

2. Battery Swelling

   • Cause: Overcharging, over-discharging, or physical damage.
   • Solution: Stop using the battery immediately and dispose of it safely.

3. Device Shuts Down Prematurely

   • Cause: Battery voltage dropped below the device's cutoff threshold.
   • Solution: Recharge the battery and monitor voltage levels during use.

4. Battery Overheats

   • Cause: Excessive current draw or charging at a rate higher than 5C.
   • Solution: Ensure the load does not exceed the maximum discharge rate (30C) and use a charger with a suitable charge rate.

Q: Can I use this battery for a 12V device?
A: Yes, but ensure the device can operate within the voltage range of 9.0V to 12.6V (the typical range for a 3S LiPo battery).

Q: How long will the battery last on a single charge?
A: The runtime depends on the load. For example, at a 10A load, the battery will last approximately 20 minutes (3300 mAh ÷ 10A = 0.33 hours).

Q: Can I connect multiple batteries in series or parallel?
A: Yes, but ensure proper balancing and use identical batteries to avoid mismatched performance.

Q: How do I safely dispose of a damaged battery?
A: Discharge the battery completely, submerge it in saltwater for 24 hours, and take it to a local recycling center that accepts LiPo batteries.
