How to Use Li-Po Battery 600 mAh: Examples, Pinouts, and Specs

The Robiton Li-Po Battery 600 mAh is a lightweight and compact lithium polymer battery designed for portable electronic devices. With a capacity of 600 milliampere-hours (mAh), it provides a reliable power source for applications requiring high energy density and low weight. This battery is ideal for powering small devices such as drones, wearables, IoT devices, and handheld gadgets.

• Remote-controlled devices (e.g., drones, cars, and planes)
• Wearable electronics (e.g., fitness trackers, smartwatches)
• IoT devices and sensors
• Portable audio devices
• DIY electronics projects

Below are the key technical details of the Robiton Li-Po Battery 600 mAh:

The Robiton Li-Po Battery 600 mAh typically comes with a JST-PH 2.0 connector. Below is the pin configuration:

1. Connection: Connect the battery to your circuit using the JST-PH 2.0 connector. Ensure the polarity matches the circuit's power input terminals (Pin 1: Positive, Pin 2: Negative).
2. Charging: Use a Li-Po battery charger that supports 3.7 V batteries. Set the charging current to 0.2C (120 mA) for standard charging or up to 0.5C (300 mA) for faster charging.
3. Discharge: Ensure the connected device does not draw more than the maximum discharge rate of 600 mA (1C). Exceeding this limit may damage the battery or reduce its lifespan.

• Avoid Overcharging: Do not charge the battery above 4.2 V. Use a charger with overcharge protection.
• Avoid Over-Discharging: Do not let the battery voltage drop below 3.0 V, as this can permanently damage the battery.
• Temperature Range: Operate the battery within the temperature range of 0°C to 45°C for charging and -20°C to 60°C for discharging.
• Storage: Store the battery at 40-60% charge in a cool, dry place if not in use for an extended period.
• Safety: Do not puncture, short-circuit, or expose the battery to fire or water.

To power an Arduino UNO with the Robiton Li-Po Battery 600 mAh, follow these steps:

1. Connect the battery's positive terminal to the Arduino's VIN pin and the negative terminal to the GND pin.
2. Ensure the battery voltage is within the Arduino's operating range (7-12 V). If necessary, use a step-up converter to boost the 3.7 V to 9 V.

You can use the Arduino's analog input to monitor the battery voltage. Below is an example:

// Define the analog pin connected to the battery voltage divider
const int batteryPin = A0;

// Define the voltage divider ratio (e.g., 10k and 10k resistors)
const float voltageDividerRatio = 2.0;

// Reference voltage of the Arduino (5V for most boards)
const float referenceVoltage = 5.0;

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

void loop() {
  int sensorValue = analogRead(batteryPin); // Read the analog value
  float batteryVoltage = (sensorValue / 1023.0) * referenceVoltage * 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
}

Note: Use a voltage divider circuit to scale down the battery voltage to a safe range for the Arduino's analog input (0-5 V).

1. Battery Not Charging

   • Cause: Faulty charger or incorrect charging voltage.
   • Solution: Verify the charger is designed for 3.7 V Li-Po batteries and outputs 4.2 V ± 0.05 V.

2. Battery Drains Quickly

   • Cause: Excessive current draw or degraded battery capacity.
   • Solution: Ensure the connected device does not exceed the maximum discharge rate (600 mA). Replace the battery if it has reached the end of its lifespan.

3. Battery Swells or Overheats

   • Cause: Overcharging, over-discharging, or physical damage.
   • Solution: Stop using the battery immediately. Dispose of it safely according to local regulations.

4. Arduino Not Powering On

   • Cause: Insufficient voltage or incorrect connection.
   • Solution: Use a step-up converter to boost the battery voltage to 9 V. Double-check the polarity of the connections.

• Q: Can I use this battery for high-current applications?
  A: No, this battery is designed for a maximum discharge rate of 600 mA. For high-current applications, consider a battery with a higher capacity and discharge rate.

• Q: How long will the battery last on a full charge?
  A: The runtime depends on the load current. For example, at a 300 mA load, the battery will last approximately 2 hours (600 mAh ÷ 300 mA).

• Q: Is the battery safe to use without a protection circuit?
  A: The Robiton Li-Po Battery 600 mAh includes a built-in protection circuit to prevent overcharging and over-discharging, making it safe for most applications.

• Q: Can I connect multiple batteries in series or parallel?
  A: Yes, but ensure proper balancing and use a battery management system (BMS) to avoid overcharging or over-discharging individual cells.
