do DC-DC converters output Watts need to equal the input Watts?
I was thinking of doing this too but using the Boost converter to power a 10s BMS.
The input watts will always be a little higher than the output due to losses. Typical efficiency is around 90%. Most of the cheap converters you see on eBay have exaggerated power ratings and will burn up if used at the stated current. Best to get one that is rated for about 2x what you actually want to run and think about adding heat sinks or fans.
