Hello, I'm adding some more series cells to my setup, but the 48V controller I have the LVC is too high for my pack, and will shut down at about 3.23V per cell. Under 40 amps of load throttling I calculated with voltage sag will only get me 60% of the pack useage. (42V LVC) (13S lithium pack) I have the exact same controller thats a 36V version that shuts down at 31.5V. It seems there is only 5 resistors that are different on the entire board between the two. I'm assuming I can pull the 36V resistors in those area's and put them on the 48V board, I know a better solution would be to figure it out and put in resistors to make the LVC cut out at 3.0V with that pack, and not 2.41V where it will be if I just swap. But I am ok with the LVC being to low, I can manage it manual watching the capacity and voltage on the Display I have. Should I just swap them all or do you guys know which ones exactly to do? Or if you know how I can change them out so its close to 3.0V per cell? Thanks
