I haven't made pancakes in years. I looked at a few recipes and chose this one. I made the batter and stored it in the fridge overnight. The batter was still lumpy because I didn't mix it enough, but when I made the pancakes the next day, not a single lump. They came out great! 
I put the batter into a couple of empty plastic drink bottles, so when I want to make more I'll pour it right into a hot pan. (Letting it sit at room temperature for about 10 minutes first and shake it up if necessary. )
