Pin Configuration

11.1V 4500mAh Lipo Battery Documentation
Pin Description:
The 11.1V 4500mAh Lipo Battery typically has 3 pins, which are:
1. Positive Terminal (Red Wire):
Pin Name: VCC or P
Voltage: 11.1V (nominal voltage)
Current Capacity: 4500mAh
Function: Supplies power to the load (device or circuit) connected to the battery.
Connection: Connect to the positive terminal of the load or a battery protection circuit.
2. Negative Terminal (Black Wire):
Pin Name: GND or N
Voltage: 0V (ground)
Function: Acts as the return path for the current flowing from the positive terminal.
Connection: Connect to the negative terminal of the load or a battery protection circuit.
3. Balance Plug (Typically JST-XH Connector):
Pin Name: Bal or B
Function: Used for balancing the individual cells of the LiPo battery during charging.
Connection: Connect to a LiPo battery charger with a balance port. The balance plug is usually a JST-XH connector with multiple pins, which are:
+ X: Cell 1 (most positive cell)
+ Y: Cell 2
+ Z: Cell 3 (most negative cell)
Note: The balance plug is only used during charging, and it's not necessary to connect it to the load.
Connection Structure:
When connecting the battery to a load or a circuit:
1. Connect the Positive Terminal (Red Wire) to the positive terminal of the load.
2. Connect the Negative Terminal (Black Wire) to the negative terminal of the load.
3. Do not connect the Balance Plug to the load. It's only used for charging the battery.
When charging the battery:
1. Connect the Positive Terminal (Red Wire) to the positive terminal of the charger.
2. Connect the Negative Terminal (Black Wire) to the negative terminal of the charger.
3. Connect the Balance Plug (JST-XH Connector) to the balance port of the charger, ensuring correct pin alignment (X to X, Y to Y, and Z to Z).
Important Safety Notes:
Always handle LiPo batteries with care, as they can be damaged or cause fires if not handled properly.
When charging, use a charger specifically designed for LiPo batteries and follow the manufacturer's instructions.
Avoid overcharging, over-discharging, or short-circuiting the battery, as this can cause damage or safety risks.
By following these guidelines and connecting the pins correctly, you can ensure safe and efficient operation of the 11.1V 4500mAh Lipo Battery.

Code Examples

### Example 1: Arduino Battery Monitoring

This example demonstrates how to use the 11.1V 4500mAh Lipo Battery with an Arduino board to monitor the battery's state of charge (SOC) using a voltage divider circuit.

Hardware Requirements

Arduino Board (e.g., Arduino Uno)
 11.1V 4500mAh Lipo Battery
 Voltage Divider Circuit (1k and 2k resistors)
 Breadboard and Jumper Wires

Code
```cpp
const int batteryPin = A0;  // Analog input pin for battery voltage measurement
const float batteryMaxVoltage = 12.6;  // Maximum battery voltage
const float batteryMinVoltage = 9.0;  // Minimum battery voltage

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

void loop() {
  int sensorValue = analogRead(batteryPin);
  float batteryVoltage = sensorValue  (batteryMaxVoltage / 1023.0);
  float soc = (batteryVoltage - batteryMinVoltage) / (batteryMaxVoltage - batteryMinVoltage)  100;
  Serial.print("Battery SOC: ");
  Serial.print(soc);
  Serial.println("%");
  delay(1000);
}
```
This code reads the battery voltage using an analog input pin and calculates the SOC based on the voltage reading.

### Example 2: Raspberry Pi Power Source

This example demonstrates how to use the 11.1V 4500mAh Lipo Battery as a power source for a Raspberry Pi, utilizing a voltage regulator to step down the battery voltage to 5V.

Hardware Requirements

Raspberry Pi Board
 11.1V 4500mAh Lipo Battery
 Voltage Regulator (e.g., LM2576-5V)
 Breadboard and Jumper Wires

Code
```python
import time

# No specific code required, as the Raspberry Pi will automatically use the voltage regulator output as its power source.
```
In this example, the voltage regulator is used to step down the battery voltage to 5V, which is then used to power the Raspberry Pi. The Raspberry Pi can be used to run various IoT applications, such as data logging, wireless communication, or automation tasks.

Please note that proper safety precautions should be taken when working with lithium-ion batteries, including using appropriate charging and protection circuits to prevent overcharging, overheating, or electrical shorts.
