Geez, no pressure. Only 100 iMiEV owners hanging on this thread right now!!
SO today I removed the cover and started to take a look inside.
First you have to remove the service disconnect entry point. The mastic is sticky, but once the four bolts are undone it lifts off easily.

Good to see everything is clean and dry, and nothing seems too swollen.

With the service disconnect, main pack positive and main pack negative show no potential.

But once you insert the link...

It's sitting at about 344 V. Which is 3.91 V per cell. At the time I pulled the pack out the GOM was saying 31 km remains and was sitting on about 1/3rd charged. Interesting.

First thing to do (after removing the service disconnect link) is to take the first couple of busbars off and undo the module clamps. The plastic covers on the main terminals pop off easily and you can fit a 12 mm ring spanner in there. Once the first two busbars are off, the module can be lifted up and the BMS plug can be removed.

After removing the covers I labelled all of the cell top terminals. I will need to mount this exact BMS module somewhere in the same location, but with remote wiring to the cell tops of the new cells. This will be a lot more complicated than I first thought, especially since cell number 1 (the most negative cell) at the opposite end of the module block.
