Pin Configuration

11.1v 4200mAh 35C 3S1P Bonka LiPo Battery Pinout Explanation
The 11.1v 4200mAh 35C 3S1P Bonka LiPo Battery has several pins that need to be connected correctly for proper operation. Here's a breakdown of each pin and how to connect them:
Pinout Structure:
The LiPo battery has a total of 5 pins, arranged in a specific pattern. The structure is as follows:
3 pins on one side (Positive, Balance, and Negative)
2 pins on the other side (Power and Ground)
Pin Explanation:
Side 1 (3 pins):
1. Positive (P+):
Function: Provides the positive voltage output of the battery
Connection: Connect to the positive terminal of your device or circuit
Voltage: 11.1V (Nominal voltage of the 3S LiPo battery)
2. Balance (B):
Function: Used for balance charging and monitoring individual cell voltages
Connection: Connect to a balance charger or a microcontroller-based balancing circuit
Note: Not connected to the device or circuit, only used for charging and balancing purposes
3. Negative (P-):
Function: Provides the negative voltage output of the battery
Connection: Connect to the negative terminal of your device or circuit
Voltage: 0V (Ground reference)
Side 2 (2 pins):
1. Power (PWR):
Function: Provides the main power output of the battery
Connection: Connect to the power input of your device or circuit
Note: This is the main power output, and the Positive (P+) and Negative (P-) pins on the other side are used for balancing and charging purposes only
2. Ground (GND):
Function: Provides the ground reference for the battery
Connection: Connect to the ground of your device or circuit
Note: This pin is connected to the Negative (P-) pin on the other side, ensuring a common ground reference
Connection Guidelines:
When connecting the battery to a device or circuit, ensure that the Positive (P+) and Negative (P-) pins are connected to the corresponding positive and negative terminals of the device or circuit.
The Balance (B) pin should only be connected to a balance charger or a microcontroller-based balancing circuit.
The Power (PWR) and Ground (GND) pins on the other side should be connected to the power input and ground of your device or circuit, respectively.
Important Safety Notes:
Always handle LiPo batteries with care, as they can be damaged or cause fires if not handled properly.
Ensure that the battery is properly connected to a balance charger when charging, and follow the manufacturer's guidelines for charging and discharging.
Never short-circuit the battery or connect it to a device or circuit that can cause excessive discharge or overcharge.
By following these guidelines and connecting the pins correctly, you can ensure safe and proper operation of your 11.1v 4200mAh 35C 3S1P Bonka LiPo Battery.

Code Examples

### Example 1: Arduino Robotics Project

In this example, we'll use the battery to power an Arduino-based robot that uses a high-torque motor. We'll monitor the battery's state of charge (SOC) using the Arduino's built-in analog-to-digital converter (ADC).

```cpp
#include <Arduino.h>

const int batteryPin = A0;  // Analog input pin for battery voltage measurement
const float batteryVoltageFull = 12.6;  // Full charge voltage (4.2V per cell)
const float batteryVoltageEmpty = 9.9;  // Empty voltage (3.5V per cell)

void setup() {
  Serial.begin(9600);
}

void loop() {
  int batteryVoltageReading = analogRead(batteryPin);
  float batteryVoltage = (batteryVoltageReading  5.0) / 1024.0;
  float SOC = (batteryVoltage - batteryVoltageEmpty) / (batteryVoltageFull - batteryVoltageEmpty)  100;

Serial.print("Battery Voltage: ");
  Serial.print(batteryVoltage);
  Serial.println(" V");
  Serial.print("State of Charge: ");
  Serial.print(SOC);
  Serial.println(" %");

delay(1000);
}
```

### Example 2: Raspberry Pi IoT Project

In this example, we'll use the battery to power a Raspberry Pi-based IoT device that uses a Wi-Fi module to send sensor data to the cloud. We'll use the Raspberry Pi's GPIO pins to monitor the battery's voltage and send notifications when the SOC falls below a certain threshold.

```python
import RPi.GPIO as GPIO
import time
import requests

GPIO.setmode(GPIO.BCM)

batteryPin = 17  # GPIO pin for battery voltage measurement
thresholdSOC = 20  # Send notification when SOC falls below 20%

def readBatteryVoltage():
  GPIO.setup(batteryPin, GPIO.IN)
  voltageReading = GPIO.input(batteryPin)
  voltage = (voltageReading  5.0) / 1024.0
  return voltage

while True:
  voltage = readBatteryVoltage()
  SOC = (voltage - 9.9) / (12.6 - 9.9)  100

if SOC < thresholdSOC:
    requests.post("https://example.com/notify_low_battery", json={"SOC": SOC})

print("Battery Voltage: {:.2f} V".format(voltage))
  print("State of Charge: {:.2f} %".format(SOC))
  time.sleep(60)
```

Remember to adjust the code to suit your specific project requirements and ensure safe handling of the battery. Always follow proper safety precautions when working with lithium-polymer batteries.
