I would like to create a class for finding the voltages of 1, 2 or even 4 batteries. The Class can be called BatteryVoltage with a default voltage value of 1.5 (AA Battery)

Must allow the user to find the total voltage of batteries when installed as a single,double, or quadruple set.
Must be able to set the voltage to calculate
Must input the kind of battery (String name

To create a class that can calculate the total voltage of batteries, you can follow these steps:

1. Define the class called `BatteryVoltage`.
2. Inside the class, declare a variable called `defaultVoltage` with a default value of 1.5.
3. Create a constructor for the class that takes an optional parameter `voltage`, which allows the user to set the voltage to calculate. If no voltage is provided, it will default to the `defaultVoltage`.
4. Create a method called `calculateTotalVoltage` that takes a parameter `batteryCount` to determine the number of batteries used (1, 2, or 4). Inside this method, calculate the total voltage by multiplying the `batteryCount` with the voltage (`defaultVoltage` or the value set by the user).
5. Create a method called `setVoltage` that takes a parameter `voltage` to allow the user to set a new voltage manually.
6. Create a method called `getVoltage` that returns the current voltage value.

Here's an example of the class implementation in Python:

```python
class BatteryVoltage:
def __init__(self, voltage=1.5):
self.defaultVoltage = voltage

def calculateTotalVoltage(self, batteryCount):
totalVoltage = self.defaultVoltage * batteryCount
return totalVoltage

def setVoltage(self, voltage):
self.defaultVoltage = voltage

def getVoltage(self):
return self.defaultVoltage
```

With this class, you can create an instance of `BatteryVoltage` and use its methods to calculate the total voltage, set a new voltage, or get the current voltage value.

Here's an example usage of the class:

```python
# Creating an instance with default voltage of 1.5
battery = BatteryVoltage()

# Calculating total voltage for 4 batteries
total = battery.calculateTotalVoltage(4)
print(f'Total voltage: {total}V')

# Setting a new voltage of 1.2
battery.setVoltage(1.2)

# Calculating total voltage for 2 batteries with the new voltage
total = battery.calculateTotalVoltage(2)
print(f'Total voltage: {total}V')

# Retrieving the current voltage value
voltage = battery.getVoltage()
print(f'Current voltage: {voltage}V')
```

Output:
```
Total voltage: 6.0V
Total voltage: 2.4V
Current voltage: 1.2V
```

You can customize the class further based on your specific needs, but this should give you a good starting point.
