Hey folks,
I installed a KT36/48SVPR-17A with a 48V battery on an old Wisper bike with a BFUN8 250W, and it's been running great until the other day.
Suddenly (after my wife used the bike to pull a heavy trailer) the power cuts out as soon as the load increases slightly.
I noticed this happens both on throttle operation and PAS. If I pedal it cuts out pretty much right away. On throttle I can ease it into running if I increase it very very carefully, but as soon as it's not flat or I pull it just a little too fast it cuts out right away. I then have to release the throttle and start over.
What could be the problem? (I've pulled heavy loads with the bike before, but probably more carefully than the wife may have done - I mention this as I have nothing else to go on that may have caused the problem, but not sure this is related to the heavy trailer)
