you'll be ok as your running the schulze, I was running 18 cells, so equivalent of 6s, the speedo used to overheat and shutdown after 3/4 minutes if I was pushing it. I got the MMM which didnt shutdown, however I didnt notice the motor temperature, didnt occur to me really.......... i suck. Anyway, im trawling the internet for a 2nd hand Nue failing that i'll have to buy a new nue.
