No Battery warnings are there any apps that provide one?

Yesterday I forgot to check my battery % and was reading and at 15% it just switched of my CoolReader app and went to main screen. Not a big deal as it needed plugging in except because Coolreader didn't get exited properly it started up where I had begun reading earlier, so I had to go through pages to find my previous ending point.

Does anyone know of an App that will give a warning beep at a preset battery level?

GSam Battery Monitor Pro (or free version) FTW!
