I understand how voltage dividers work, but don't have a controller board to hand to follow how you changed the layout here (I only have one left, and that's packed away ready to ship). I was hoping you could clarify where you planted the left leg of that resistor so I could follow what you did once I've got one of these apart again (I'm getting another order in shortly). The detail on that picture makes it hard to see what's going on on that left side, and my own photos don't cover that section in close-up.
Well done on figuring this out. I ran all over the place with a continuity tester trying to find the equivalent of that R12 divider but just couldn't locate it. Layout is evidently slightly different and I didn't find what I expected.
[EDIT] I just saw that picture of yours clearly labelling everything. Thanks a lot! I'll give this mod a go when I get in more of these. Did you think of maybe routing the extra resistor via an external self-connector (like the 60/120 degree plug) to make the controller dual mode? Might be handy for 48V users who are planning to upgrade...
