Battery monitoring circuit on DS2438

I need a circuit diagram for being able to isolate and monitor a 14s lithium bank.

For each pack i want to have 1 DS2438 voltage monitoring device or any other device using 1wire. Independent devices for each of the 14 packs. The problem is that they are connected in series and that the DS2438 does not have an isolated Vsens-. Can this be achieved? and if so to what cost? I want as little components as possible on each node. Low price per node as well. preferable all devices power comes from the 1wire bus.

Preferable quite good accuracy between 2.8 and 4.2V.

Note: That this is just about getting a schematic that will work. And should not be hard to do for someone that know how to isolate Voltage meassurements
