Hello.
I'am new here on Endless Sphere.
It seems to be a lot of people who tinker a lot.
I have a problem that i hope someone can help me with.
A Bafang 250 W hubmotor with a KT36SVPR-LCD controller. The problem i have is that sometimes the motor wont work.
When i pedal, the motor helps me for a while, and suddenly it dont. After a couple of seconds it begins to work again.
When i got it, it worked fine. It was this summer.
And it can work for a couple of 100 meters. And then the same.
It seems to work ok in the beginning of the ride. And even when testing indoors it seems to work ok.
I have tried with a different controller of same type, but the problem remains.
Earlier i had lead acid batteries, but today i changed to Lithium, but as always, the problem remains.
I am beginning to think if it is the controller that doesn't like cold. But it's not even freezing here.
And if it is the PAS that is the problem, it should work bad all the time i think.
Does anyone have an idea what the problem could be?
