We'll I don't know about using a full fledged LCD, although that would be cool... and my encouragement if you decide to try. But, you might want to look into a Digital Panel Meter, or a regular panel meter. They are a simple solution giving you an idea of how much charge you have left.
All Electronics has some pretty affordable ones. In fact we used one on our FRC robot last year. Ours was the only one that had one, and the engineer who inspected our robot kind of liked it.
