The 452096 2500mAh battery typically has two terminals for connection:
Pin | Label | Description |
---|---|---|
1 | + (Positive) | Positive terminal for power output |
2 | - (Negative) | Negative terminal for power output |
Note: Some variants may include a built-in protection circuit module (PCM) for overcharge, over-discharge, and short-circuit protection.
+
) to the positive rail of your circuit and the negative terminal (-
) to the ground rail.The 452096 2500mAh battery can be used to power an Arduino UNO via its VIN pin. Below is an example circuit and code to read the battery voltage using an analog pin:
// Define the analog pin connected to the voltage divider
const int batteryPin = A0;
// Define the voltage divider ratio (e.g., 10kΩ and 10kΩ resistors)
const float voltageDividerRatio = 2.0;
// Define the reference voltage of the Arduino (5V for UNO)
const float referenceVoltage = 5.0;
void setup() {
Serial.begin(9600); // Initialize serial communication
}
void loop() {
// Read the raw analog value from the battery pin
int rawValue = analogRead(batteryPin);
// Convert the raw value to the actual battery voltage
float batteryVoltage = (rawValue / 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: Ensure the voltage divider reduces the battery voltage to a safe level (below 5V) for the Arduino's analog input.
