1 | # Part IX: Use a high side power switch for effective battery management
2 | 
3 | In this project, you will explore how you can use the Infineon BTS50055-1TMB or BTS50080-1TMB PROFET high-side power switch to take the battery management of your quadcopter drone to the next level. The Youtube video below explains the necessary electronic circuits and the necessary code.
