...Which is why Lithiums are the battery of choice. They fight HARD with little sag until close to the very end, where they fall flat on their face.

Contrast that to our lead batteries (Electro-Metro & Electric Booger) that let us know very quickly when they are not completely full anymore! I guess the 72V starting voltage doesn't help, either....
