I already have the Lyen 18fet controller, I guess it wont harm anything if I go lower just wondering if performance is hindered is all in the controller itself.
However the statement says a lot and I understand 36V, and 100V, but if I am only going down from 72 to 60 shouldnt be any issues should there?
72V battery optimized (for higher or lower voltage & current such as 36V-100V, you may need to change the resistor network to avoid damage to the voltage regulator)
65A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.6v
