battery indicator with adjustable discharge curve

I've not seen the kind of thing you describe, but here's a general purpose programmable meter that looks like it could be pressed into service for this application:

You would need to make a resistor divider to bring the battery voltage down to the 0-5V range, then set up the proper y = mx+b setting to get the readings you wanted (e.g. 0-10 as a logical fuel gauge for non-techies instead of true voltage). An example of such a divider used on a CA3 is described in section "5.9 Powering the CA / High Voltage Vehicle Support" of the CA3 [strike]Un[/strike]official Guide.
As an alternative you could use a conventional meter and just monitor a single balance lead to show a 'typical' cell voltage. Not too elegant, but workable.
