Et voilá, you are getting the maximum payout now. Congratulations!

Disclaimer: I recommend to have minimum of 500 LSK in your voting account, because it would take several weeks or months to get the LSK back, you've just spent on voting. The more LSK you have, the more rewards you get. Note: Lisk will switch to a cheaper and better dynamic fee system soon™ but it will take some more months, I guess.

How many LSK do I get per 500 LSK?
You can use http://www.liskware.com/ to check how many LSK you'll will get approximately (if you get an error-message like "application error" try to reload the site). With 500 LSK you should currently get around 5 LSK per month.
