More questions, fixes and splitting of categories

Hey again eko! 

Some more small(ish) stuff I could fix for ya, not sure why the separate category for @cordoval's battery was there, I know he got a PR in so not sure if this has a purpose, let me know.

- fixed some questions and typos
- split up some questions into more appopriate categories (including Cordoval's Battery 1?)
- fixed yaml files not ending with proper LF
