This is a remix from Tavero´s Rechargeable battery mod for Flysky i6 transmitter

I wanted to adapt this mod for use with some 9v rechargeable batteries I had at home.
To do this I redesigned the part to handle a switch and used the following hardware components:

• Buck converter LM2596 to adapt voltage
• 10x15mm Switch
• 9v Rechargable battery
• Battery connector
• M3x10 screws for attaching the LM2596

I also had to solder to join the components together and I used hot silicon to glue them to the case.
