I have a battery powered trimmer (can't remember the voltage off the top of my head) and it works great. Haven't run into any issues with it dying before I was able to complete the job. Whether or not battery powered is the way to go will depends on quite a few things, like the size of your yard, how tall the grass you will be cutting it is, how often you plan to use it, etc...
