Introduction

In this article, we will Delve into the exciting world of Betaflight 4.0 and explore one of its groundbreaking features - automatic pig profile selection Based on battery cell voltage. As the drone industry evolves, we find ourselves using different cell voltages on our quads more than ever before. Gone are the days when a quad was simply a 3s or 4s setup. With the rise of micro quads and diverse battery options, pilots now have the flexibility to fly on 1s, 2s, 3s, 4s, 5s, or even 6s setups. However, each battery voltage requires specific tuning parameters to achieve optimal performance, which can be quite cumbersome to manage manually. This is where the automatic pig profile selection feature comes into play, making our lives as quad pilots a whole lot easier.

Understanding Different Battery Cell Voltages

Before we dive into the details of the automatic pig profile selection feature, let's take a moment to understand the significance of different battery cell voltages. Traditionally, when building a quad, there was a standard cell voltage for which we would tune our PIDs and other parameters. However, with the advent of micro quads and varied applications, pilots started exploring different battery options. For instance, a micro quad like the Mobula 7 or the Trashcan may run on 1s or 2s batteries, while a 3-inch quad could utilize 3s or 4s batteries. Even larger quads with high KV motors might require 5s for maximum power and 4s for cruising or proximity flights. Hence, it is essential to have different pig profiles for different battery voltages to achieve optimal performance.

The Need for Different Pig Profiles

When it comes to tuning a quadcopter, having the right PID values makes all the difference. But finding the perfect PIDs for a particular battery voltage can be challenging. The default PIDs may work reasonably well on a wide range of quads, but those who Seek precision and fine-tuning understand the need for specific pig profiles. A set of PIDs that work flawlessly on a 4s setup might not deliver the same performance on a 5s setup. Betaflight addressed this issue by introducing multiple pig profiles, each capable of having its own set of PIDs. However, manually selecting the correct pig profile for the battery voltage can be quite bothersome.

Manual Selection of Pig Profiles

In earlier versions of Betaflight, selecting the appropriate pig profile required navigating through the Betaflight Configurator and manually choosing the desired profile for a specific battery voltage. While this approach worked, it was not the most intuitive or efficient solution. Pilots had to remember which profile corresponded to each battery voltage and manually switch between them every time they changed batteries. This process could be time-consuming, especially if You were working with different battery voltages regularly.

Introducing the Automatic Pig Profile Selection Feature

To address the pain points of manual pig profile selection, Betaflight introduced the automatic pig profile selection feature. This exciting addition to Betaflight's arsenal allows the software to recognize the battery voltage and automatically choose the appropriate pig profile. Instead of relying on manual selection, pilots can now focus on flying, knowing that the quad is using the right tuning parameters for the given battery voltage. With this feature enabled, betaflight will detect the voltage of the battery you plug in and select the pig profile associated with that voltage.

How to Set Up Auto Profile Cell Count

Now that we understand the importance of having automatic pig profile selection, let's dive into the steps involved in setting up the auto profile cell count feature. Please note that the following instructions assume that you already have different pig profiles set up and assigned to the respective battery voltages.

1. Open the Betaflight Configurator and navigate to the CLI (Command Line Interface).
2. Type "profile" followed by the number of the pig profile you want to configure. Keep in mind that Betaflight uses zero-based indexing, so profile 1 would be profile zero, profile 2 would be profile one, and so on.
3. Once you have entered the desired profile number, set the auto profile cell count by typing and equal sign, followed by the number of cells you want associated with the profile. For example, if profile 1 is for 4s, you would type "set auto profile cell count=4".
4. Repeat the process for the other pig profiles and their respective battery voltages. For instance, if profile 2 is for 5s, you would type "set auto profile cell count=5" after entering profile 2.
5. After configuring all the pig profiles, don't forget to save the changes by typing "save" in the CLI and hitting enter.

With the auto profile cell count set up, your quad will automatically select the correct pig profile based on the battery voltage you plug in. It's that simple and convenient!

Troubleshooting: Incorrect Cell Count Detection

While the auto profile cell count feature works flawlessly in most cases, you may occasionally encounter issues with incorrect cell count detection. For example, if you have a fully charged or high-voltage 4s pack, Betaflight might mistake it for a discharged 5s pack. As a result, your OSD may display a low battery warning throughout the flight, hampering your flying experience. To address this problem, you can adjust the maximum cell voltage parameter in the power and battery tab. By increasing the maximum cell voltage, Betaflight will be able to accurately determine the number of cells in your battery, thereby avoiding false detection. For most quads, setting the maximum cell voltage to 4.4 should suffice.

Advanced Options: Locking Profiles and Skipping Profiles

In addition to the straightforward setup of auto profile cell count, Betaflight offers advanced options for fine-tuning your pig profile selection. If you wish to lock a specific profile and prevent it from automatically switching, you can set the auto profile cell count for that profile to zero. Conversely, if you want to skip a profile and move to the next one, you can set the auto profile cell count to -1. These options provide greater flexibility for pilots who require specific control over their pig profile selection.

While these advanced options may not be necessary for most users, those who crave complete customization and have advanced tuning requirements can further explore them. The official Betaflight GitHub page provides in-depth discussions and examples of how these options can be utilized.

Using the Betaflight OSD for Profile Validation

To ensure that the correct pig profile is being selected, you can enable the Pin rate profile setting in the Betaflight OSD tab. This setting displays the Current pig profile and rate profile being used, offering real-time validation of the selected profile. While not mandatory, it can be helpful during testing and debugging to ensure that the quad is loading the desired profile.

Conclusion

The automatic pig profile selection feature in Betaflight 4.0 elevates the quad tuning experience to a whole new level. By eliminating the need for manual selection and automating profile switching based on battery cell voltage, pilots can now focus on flying and enjoy optimal performance across different setups. Whether you're a seasoned pilot looking for greater precision or a beginner seeking simplicity, this feature is sure to make your quadcopter tuning process a breeze. So, go ahead, explore the world of Betaflight 4.0, and experience the advantages of automatic pig profile selection. Happy flying!
