TS100 Power Box 12V to 24V

I have 3 of 3s lipo batteries lying around and I don't want to waste them. Besides, TS100 is not that powerful when the voltage is below 16V. So I made this converter and set the output to 22V.

It works perfect. But the TS100 is sensitive about high voltage above 24V AFAIK. So I think it is better you to set the output about 22V maximum. Because when the input voltage is given to the converter, I saw some ripples on output voltage when inspected with my oscilloscope which has a highest limit
