Hi guys! My name is Sergey, I am from Russia, so please forgive me my poor english. I need your help. I've got a controller, which was bought from V-power HK3 in e-bay store (36V, 800W).I want to modify it to 60V, and if its possible to 1000W. Somehow just searching through the forum I saw information about changing an input resistor (3W 3pcs parallel) and increasing shunts power and something about adding resistor between 6th and 7th LM358 legs. But now when I actually need this information I cant find it again! So please if you know where it was discribed give me a link or if you know how to do it please tell me. I really hope for your assistance.
P.S. If you need proper photo please just let me know.
