Something similar happened to me, but I also ran out of gas with the BBS02B. It was a faulty one-way bearing that acts as a clutch. I think it will also be something like that.
I had set 32 kmh and I wanted 35 km/h I could only set 31.5 kmh but not higher.
I also uploaded a new FW, it went OK, I'll try tomorrow.
The weather was not good today
I tried it with version 1.2.18 and it could not be changed. Now there is the latest 1.2.26. Try something else?
it lists it>
Dealer or Assembler can't charge it to bigger
I'm asking for advice, I have a Besst tool, everything works fine for me, but I can't increase the speed but only decrease it. Is this caused by the Besst tool itself, or is it just a bug in the Python login?
I received this reply today:
dear,
Do you have the best tool or you just want the firmware, I could send you the firmware but you have to give your serial number.
Sorry for the inconvenience.
best regards,
