If you solder off the LVC solder jumper, does it revert back to a 48V 13S controller of something like like 42V LVC (as stated on hksunwins 48V models.)
I am totally guessing that it just might. I was using 60V battery back with the LVC unsoldered on a hksunwin 60V controller, working fine. I just kept a very close eye on the voltage. Now I am using 10S 36V pack and I get nothing. Funny thing is though that the Self Study works, throttle does not reverse the rotation, so I tested it and the throttle, its fine. I can touch the red and sensor wires on the controller and it will reverse. Ignition is connected up.
I see no 48V LVC pads on the pcb. Been looking carefully around the area where the LVC pads are, and over the entire board and I see nothing. hksunwin sells no 36V model, so that brings me back to if no LVC pads are jumpered, its goes to a 48V controller with a LVC of 42, so 13S is 54.6V, and a 42V LVC is 3.25V/cell.
Before I do anything, I will see what I can do to add to my 10S 36V battery, might just have to go back to 60V.
