• Robotics and automation systems
• Internet of Things (IoT) devices
• Backup power supplies for microcontrollers and sensors
• DIY electronics projects and prototyping

The GKA Lithium-Ion 9800mAh battery is engineered to deliver consistent performance while maintaining safety and efficiency. Below are the key technical details:

The GKA Lithium-Ion 9800mAh battery typically comes with two terminals for connection:

Note: Some variants may include a built-in protection circuit module (PCM) to prevent overcharging, over-discharging, and short circuits.

1. Connection:
   • Connect the positive terminal of the battery to the positive input of your circuit.
   • Connect the negative terminal to the ground of your circuit.
2. Charging:
   • Use a compatible Lithium-Ion battery charger with a constant current/constant voltage (CC/CV) charging profile.
   • Ensure the charging voltage does not exceed 4.2V to prevent damage.
3. Discharging:
   • Avoid discharging the battery below 3.0V to maintain its lifespan.
   • Use a load that does not exceed the maximum discharge current of 2A.

• Safety: Always handle the battery with care. Avoid puncturing, short-circuiting, or exposing it to high temperatures.
• Storage: Store the battery in a cool, dry place when not in use. For long-term storage, maintain a charge level of 40-60%.
• Protection Circuit: If the battery does not include a built-in PCM, consider adding an external protection circuit to safeguard against overcharging and over-discharging.
• Arduino Integration: When using the battery to power an Arduino UNO, ensure the voltage is regulated to 5V using a step-up converter or a voltage regulator.

/* Example: Reading a sensor value with Arduino UNO powered by GKA Lithium-Ion 9800mAh
   Ensure the battery voltage is regulated to 5V before connecting to the Arduino. */

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
  pinMode(sensorPin, INPUT); // Set the sensor pin as input
}

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: Charger not compatible or damaged.
   • Solution: Use a charger designed for Lithium-Ion batteries with a 4.2V output.

2. Battery Drains Quickly:

   • Cause: Excessive load or battery nearing the end of its cycle life.
   • Solution: Reduce the load or replace the battery if it has exceeded 500 cycles.

3. Overheating During Use:

   • Cause: Current draw exceeds the maximum discharge current.
   • Solution: Ensure the load does not exceed 2A. Use a current-limiting circuit if necessary.

4. Battery Voltage Drops Below 3.0V:

   • Cause: Over-discharging.
   • Solution: Recharge the battery immediately. Use a protection circuit to prevent over-discharging in the future.

• Q: Can I connect multiple GKA Lithium-Ion 9800mAh batteries in series or parallel?

  • A: Yes, you can connect them in series to increase voltage or in parallel to increase capacity. Ensure all batteries are of the same type and charge level before connecting.

• Q: How do I know when the battery is fully charged?

  • A: A Lithium-Ion charger will typically indicate full charge when the current drops to a minimal level while maintaining 4.2V.

• Q: Is the battery safe for outdoor use?

  • A: Yes, but ensure it is protected from water and extreme temperatures. Use a weatherproof enclosure if necessary.

• Q: Can I use this battery to power a motor?

  • A: Yes, as long as the motor's current draw does not exceed 2A. Use a motor driver circuit for better control and safety.
