I've done some spreadsheeting on changing the amount of series cells, and it doesn't matter. I've gone through all combinations of NCA and NMC cells with 94-102S, and you can never get more than approx. 40% of nominal capacity out of the extender pack before VLBW. There is basically still well over half of the extender pack left after the car already says it's empty. In practice, it's even more pronounced; I get my VLBW at about 130km these days, and can drive it down to about 250km. I mean, for now it makes estimating range very simple: just multiply whatever the car says it can do by 2.
So don't even bother. Just keep the same series amount of cells, it will be best for cycle life anyway. I'm currently working on the electronics that will fix the displayed range, this will be done and tested before the summer holidays.
Edit: also, it's probably informative to tell you that I have had the contactor failure DTC once as well, when replacing my MOSFET driver solution with a new custom board (as shown in my last video). A firmware bug caused the contactors to not close at the correct time. I was really ragequitty at the time but persisted, reflashed corrected firmware, cleared DTCs and waited a bit, and it all went away. I don't think I actually damaged anything, there must be some sensor that actually does the contactor-welded-closed-measurement that is sensitive to something else causing stray DTCs. Same goes for the isolation DTC, it intermittently shows even though I've gone through the entire service manual procedure of narrowing down where it could come from. Some of these sensors are just a little bit too sensitive it seems.
