    How hard Q75 can be pushed

    without failing of course... for short bursts of hill climbing power. I have Q75 (200W) interfaced to LSW-675 (7A continuous, 15A peak) with KM5S display which is capable of live measuring power in W, and also limiting current within 1-15 A adjustable range. Some easy math: 7A x 36V = 250W...

    Pairing Q75 with LSW-675 NOT S06P

    From BlueMySky Battery. Why? I have the 201 rpm in a 20 inch wheel with S06P controller (plus LCD-1 S) which lose sync and thus power plus get a horrible squealing noise with high power at low speed. Just when I need torque to climb a hill! BIG problem. One solution to this when using a S06P...

    What controller do you use with Q75?

    I got S06P (with LCD-5) which has problems interfacing with Q75. (see https://endless-sphere.com/forums/viewtopic.php?f=2&t=81852) BMSB list ONLY one more controller compatible with Q75: 36Volts 250Watts LSW-675 Sine Wave Controller with King Meter KM5S LCD Display Do you know if anybody else...

    Q75 - loud(!) squealing noise with acceleration

    What it is, how to stop it and how bad it is for the motor/gears? Gentle throttle use does not elicit that noise. Initially, I thought that the axle spins in the dropout, but anti-rotation washers are installed correctly. See photo... My system Q 75 36 V, 201 rpm, 20 inch front Controller...

    BMS system assembled - motor does not spin

    Finally completed my DIY set-up. Raised the front wheel from the floor so it could spin freely. Connected battery. Display is live, speed sensor works if I spin the front wheel manually. The red LED of the HWBS is lit. The throttle does not work, i.e. motor does not spin. Do I need to enter any...

    Connections to S06P controller

    Got the kit from BMS and I am beginning the assembly for testing. I need your help with figuring out connections coming out of the controller S06P.

    Motor energy use vs RPM @constant load

    Will be ordering a motor for a small folding bike with 20 inch, tire diameter 1.6 m Have 2 choices for motor rpm, 201 and 328. Prefer 201 rpm for a max speed of 19 km/h and good hill climbing. However, at that configuration I will expect to ride a lot at max rpm BUT at relatively low load...

    Ultra light kit for 20" front geared hub

    Have a small folding bike with standard 100 mm fork. Want the simplest, lightest setup for throttle/switch for motor under 250w, either 24 or 36V. (no pedelec) Leed bike would be OK but they use heavy Bafang motor @ 3 kg. http://www.e-bikerig.com/ I have learned that 36V motor at 1.5 kg exists...
