Don't forget about the concept of a voltage divider... Two equal value (something high for low watt dissipation) resistors in series across the pack, with your analog volt meter's + connected to the middle... Your volt meter will display 1 for every 2 pack volts (40 for 80v, 60 for 120v, 80 for 160v, etc).

My electrics knowledge is limited in this voltage range, but a quick gander at Ohm's Law & a calculator, gives me two 30kohm'ers for 1/4 watt resistors @ 144v nominal / 170v max.
