Thanks, i think it is the same file as the app finds in the internet folder.
I'm using this controller in a 193kg heavy scooter , Masini Extremo, and feed a 72V10000W QS273 motor with a little over 30kW.
21S Battery 400A and 1400A phase.
I'm not shure if I should try to upgrade, because only things that are missing are regen untill zero and the variable throttle regen function. It only does brake regen. The ND72680 i used before had all this functions, but was two years newer. The ND72450 I bought and installed a few weks ago also does not offer this functions.
