Hello Jay, I strongly recommend you this one: the VICTRON ENERGY BMV-700H (H means for high voltage)
https://www.victronenergy.com/battery-monitors/bmv-700 I had the same need months ago, and after some folks recommendations here and some more extensively search the web I found this one. It is a true Ah-Wh-V-Amps and lot more information meter system (second battery monitor, hrs left, alarms output, peukert, cycle, temp sensor, proprietary network connectivity, buzzer, etc) either for Lead-Acid or Lithium batteries or other chemistries. From 6.5 to 96V and for 60 to 385V (BMV-700H the one you need) I think none of the ones in the market, this size and price beats this one. Ing.

I want to put it into the hole that will be left by a Curtis 900R (lead acid) battery monitor in my dash, so the form factor should be a round automotive 2" diameter panel type. I'm willing to pay extra to have it powered by the pack (118-135 volts) and not require an isolated 12 volt supply. I'm willing to pay extra to have it use a hall effect sensor (as opposed to a shunt), as I don't need it to be terribly accurate and for my mounting position a hall effect will be easier/cleaner. Ideally I'd like to wire it up to pack +/- and the magnetic current sensor and be done. Suggestions?
