My original RAD MINI ST2 Controller failed at 6995 miles.  Electro Bike World recommended that I upgrade to their "35a Controller & KT-LCD8H Rad Combo".  I ordered and received the upgrade.  The upgrade solved my controller problem.  I have plenty of hills where I live at and noticed the torque improvement on the hills.  The only concern I have now is when I'm at max speed #5 I go up hills fast, but the wattage may peak as high as 1300 Watts.  Can the 750-Watt motor burn up?  Does anybody know if there are current limiting safeguards in place?   I was considering changing C5 from "10" to a lower number.
