    My aim was to discharge down to one volt per cell, 12 volts per pack.
    You obviously don't use power tools in the construction industry. Thanks anyway.

    Voltage reference, comparator, relay, 18V power supply. Not much to the circuit. Check out the LM393 datasheet.

    A 12V 5W zener in series with a 20Ω resistor should do it.

    That's what I was looking for. Thanks I'll try it.

    Sure that would also work if you wanted to do it an easy way.
