The following table outlines the key technical details of the Lifepo4 Baterai 3.2 20Ah:

The Lifepo4 Baterai 3.2 20Ah typically has two terminals for electrical connections:

1. Connection: Connect the positive terminal of the battery to the positive rail of your circuit and the negative terminal to the ground or negative rail.
2. Charging: Use a LiFePO4-compatible charger with a maximum charge voltage of 3.65V and a current limit of 20A to safely charge the battery.
3. Discharging: Ensure the load does not exceed the continuous discharge current of 20A. For short bursts, the peak discharge current of 40A can be used.
4. Protection Circuit: It is recommended to use a Battery Management System (BMS) to prevent overcharging, over-discharging, and short circuits.

• Avoid Overcharging: Do not exceed the maximum charge voltage of 3.65V to prevent damage.
• Prevent Deep Discharge: Avoid discharging below 2.5V to maintain battery health and longevity.
• Temperature Monitoring: Operate the battery within the specified temperature range (-20°C to 60°C) to ensure safety and performance.
• Storage: Store the battery in a cool, dry place at around 50% charge for long-term storage.
• Wiring: Use appropriate gauge wires to handle the current without overheating.

The Lifepo4 Baterai 3.2 20Ah can be used to power an Arduino UNO. Below is an example of how to connect the battery:

1. Connect the positive terminal of the battery to the VIN pin of the Arduino UNO.
2. Connect the negative terminal of the battery to the GND pin of the Arduino UNO.

// This code demonstrates a simple LED blink using an Arduino UNO powered by
// the Lifepo4 Baterai 3.2 20Ah. Ensure the battery is connected properly.

const int ledPin = 13; // Pin connected to the onboard LED

void setup() {
  pinMode(ledPin, OUTPUT); // Set the LED pin as an output
}

void loop() {
  digitalWrite(ledPin, HIGH); // Turn the LED on
  delay(1000);                // Wait for 1 second
  digitalWrite(ledPin, LOW);  // Turn the LED off
  delay(1000);                // Wait for 1 second
}

1. Battery Not Charging:

   • Cause: Charger not compatible with LiFePO4 chemistry.
   • Solution: Use a charger specifically designed for LiFePO4 batteries.

2. Battery Drains Quickly:

   • Cause: Excessive load or deep discharge.
   • Solution: Ensure the load does not exceed the rated discharge current. Avoid discharging below 2.5V.

3. Battery Overheats:

   • Cause: Operating outside the recommended temperature range or excessive current draw.
   • Solution: Monitor the temperature and ensure the current draw is within the specified limits.

4. No Output Voltage:

   • Cause: Battery protection circuit activated due to over-discharge or short circuit.
   • Solution: Recharge the battery to reset the protection circuit.

Q1: Can I connect multiple batteries in series or parallel?
A1: Yes, you can connect multiple batteries in series to increase voltage or in parallel to increase capacity. However, ensure all batteries are of the same type, capacity, and charge level. Use a BMS for safety.

Q2: How do I know when the battery is fully charged?
A2: The battery is fully charged when the voltage reaches 3.65V and the charging current drops significantly.

Q3: Is the battery safe for air travel?
A3: LiFePO4 batteries are generally safer than other lithium chemistries, but always check airline regulations before traveling.

Q4: Can I use this battery for high-power applications?
A4: Yes, the battery supports a peak discharge current of 40A, making it suitable for high-power applications within this limit.
