Am I phrasing this sentence correctly?
Una de las mejores carateristicas de mi madre es ella es muy simpatica y tranquilla. Do I not need to say es twice? Like if I take out ella es and it would just be mi madre es muy .... Would the sentence still mean that one my moms best characteristics is that she is nice and relaxed.

You need es in both clauses in my opinion as the subjects are different, you can drop ella- you need the que that Ann points out, your spelling on: carateristicas, simpatica and tranquillo is off- match tranquila as Ann says but one l.
Una de las mejores características de mi madre es que es muy simpática y tranquila.
That only leaves the question as to whether simpática y tranquila comprises one characteristic or two. But I will leave it as one.
If you want one es and no que- you could try a rewrite, but note I still had to replace one es with ser- the parent verb, but made it function as a noun:
Ser muy simpática y tranquila es una de las mejores características de mi madre.
Hint- if you have Microsoft word, drop your sentence in there, select it and set the language to whatever form of Spanish you prefer, then spell check it. Then at least we don't have to spend time fixing stupid spelling errors- just the ones where your misspelling created some other existent word.
This is not exactly an answer to the question you asked. I'll leave that to someone else. However, I will say that you need "que" between "es" and "ella." English speakers often leave out the "that" that links an independent and a dependent clause, but Spanish speakers always use it. Also you need to change "tranquillo" to "tranquilla," the feminine form of the adjective, because it is describing your mother, who is female.
