Does anyone know of a really simple method for showing battery charge? Even as simple as a red, yellow, green led? Or if there is a simple LED of some sort that would show it as a percentage.
I built a battery powered USB hub and I need to know how much charge the battery has. If I have a battery die while transferring data from one or two hard drives it could make for a bit of a mess.
