I have ran 3s in my Senton, Typhon and Kraton without any problems and the low voltage still works with it. Maybe the older red BLX180 couldn't but all of mine have the newer black
BLX185. I believe that the
BLX185 even says right on it 3s-6s. I have even ran 2s but then I need to run an external low voltage alarm as the ESC isn't capable of reading 2s.
