      I was able to fool the Plus controller t o accepting a 15s and 16s battery.
      Lia pointed in the right direction and I managed to calculate the resistor values for the Plus to accept higher voltage batteries.
      After a test ride, the Plus pushback reared it's ugly head and I'm working on how to make the XR/Plus speed patch work on Rewheel. I know nothing about coding, but I can see the code and if I stare at it long enough maybe something will make sense, haha.
      The Plus has to run zombie with a loop key and no bms for now, I have a preproduction small charge only bms I'm testing out.
      Stock resistor is 33k, 15s is 30k and 16s is 28k. I also changed the large caps to 80v ones.
      A full 15s battery(63v) will show as 57v (full Plus battery voltage) on the FM app.IMG_E7496.png IMG_7545.png
