Friend at school designd a quick little circuit to tell us when the battery is low. It involves an opt amp and a few parts.
When the battery drops to 3 volts a cell a light will come on.
I'm glad you guys agree in the case of the MP7, I figured I couldn't be too wrong with that.
I had a dream last night where the battery compartment was huge. It held the battery, a repair kit, a can of pop and some yogurt and other misc stuff. So ya....
