Motor Now Cutting Out......??

[camebeloc]

could the controller be advancing the timing at some speed in order to weaken the field so a lower voltage setup can reach higher speeds(stock sla). When confronted with a higher voltage, it draws too much current at that point and trips the hard limit.......I have a lyen 12 fet that does this with the hs35. seems to have two "speeds", like a turbo almost. but it really sucks the amps when it changes to high .

I think the op should try some lower voltage lipo to see what happens.

Thank you Hydro one for joining our little 'puzzle game'

I will do just that as ykick also suggested, try same and test again on a lower voltage(12s) and 50v setup

And will report in about a week, bike wont be out any earlier it looks like, as temps here are to fall back to 1-5 c early in week.....



Really appreciate all the help and info folks, soon I think we will know more....
