Design with Lifepo4 Baterai 12.8V 200 AH in Cirkit DesignerThe LiFePO4 Battery 12.8V 200Ah (Manufacturer: ESP32, Part ID: WROOM 32D) is a high-capacity lithium iron phosphate battery designed for applications requiring reliable, long-lasting, and safe energy storage. With a nominal voltage of 12.8V and a capacity of 200Ah, this battery is ideal for use in renewable energy systems, electric vehicles, backup power supplies, and off-grid setups. Its superior thermal stability and long cycle life make it a safer and more durable alternative to traditional lithium-ion batteries.
This circuit is a solar power system that charges a 12V 200Ah battery using a solar panel through a solar charge controller. The system also includes a DC-DC buck converter to step down the voltage from the battery for powering a load.

This circuit is designed to charge a 12V 200Ah battery using power from a solar panel, with a solar charge controller regulating the charging process. An AC source is rectified to DC using a bridge rectifier, which then feeds into a step-up boost power converter to produce a higher voltage output, possibly for an external AC load. Additionally, a DC-DC converter is used to step down the voltage to 5V for use with a 5V connector, likely for low-power devices or logic circuits.

To power an Arduino UNO using the LiFePO4 battery, you can use a DC-DC step-down converter to regulate the voltage to 5V. Below is an example circuit and code:
// Example Arduino Code: Reading Battery Voltage
// This code reads the battery voltage using an analog pin and displays it
// on the serial monitor. Ensure a voltage divider is used to step down
// the battery voltage to a safe range for the Arduino's analog input.
const int analogPin = A0; // Analog pin connected to the voltage divider
const float voltageDividerRatio = 5.7; // Adjust based on your resistor values
const float referenceVoltage = 5.0; // Arduino reference voltage (5V for UNO)
void setup() {
Serial.begin(9600); // Initialize serial communication
}
void loop() {
int sensorValue = analogRead(analogPin); // Read analog value
float batteryVoltage = (sensorValue * referenceVoltage / 1023.0) * 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
}
| Issue | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Charger not compatible or faulty | Use a LiFePO4-compatible charger. |
| Battery discharges too quickly | Load exceeds battery capacity | Reduce load or check for short circuits. |
| Battery overheating | Overcharging or excessive discharge current | Ensure proper ventilation and use a BMS. |
| Voltage drops below 10.0V | Over-discharge | Recharge immediately to prevent damage. |
