Post up the schematic. It would be very beneficial to those who want to do an EV conversion someday. EV fuel gauge.

IMHO (in my honest opinion), a voltmeter wouldn't make a very good EV fuel gauge. Batteries in general, and NiMH chemistries in particular provide most of thier capacity in a fairly tight voltage range, typically 1.25 to 1.0 volts per cell. The perfect analogy would be a narrowband O2 sensor. A voltmeter would really only show full charge, charge but not fully charged, and dead battery. Perhaps the new Lithium ion chemistry is different. I don't know much about LI except that they can get very hot and are very explosive if charged or discharged properly.
