    making q85 work

    I do not have LCD screen, is it needed to turn the controller on? I thought only power cables are required to be connected. I have tested the thumb throttle input voltage it is 4v This is the controller wire diagram https://bmsbattery.com/index.php?controller=attachment&id_attachment=49

    is there any way to make this motor rotate in reverse ? I offer $20 thank you gift for anyone who can give clear instructions to reverse the bbs01 spinning direction 8) The external parts to the motor in my construction allow reverse rotation of motor shaft i.e. no external freewheel.

    I agree, but there is 250w limitation in some countries so maybe it is the same model with just soft limit of 250w. here is the text on my bbs 01, it is written 36v 15A (~540w) and 250W

    Those are both bbs01 36v versions, the only difference i see in two products in the power.

    are the bbs01 250w and 500w the same model but programmed with different max amps ? i.e. if I get 250w and reprogram it to allow up to 500w will I have the same perforamnce as with 500w motor?

    Is there a way to problematically change the rotation to reverse direction ?
