    What kind of plugs do you recommend ? I've already changed all the plugs by Anderson plugs (bought from Aliexpress). I was thinking about soldering controller's wires with motor's wires. For now motor is quiet (still a bit noisy on first level but it's ok). On s12s torque simulation controller...

    Matching controller with rear hub motor?

    Hello, be careful, i bought a kit from banggood, it's quiet with the original controller. I tried three other one, and i can't find a controller as quiet as the one from the kit, they are really noisier. First movie original controller vs kt48 500w (not real sine wave) controller from...

    Need help first build with kt-lcd3

    I think i've found the L1 setting explanation. From the Kt-LCD8S manual : "L1 parameters are applicable to the automatic under-voltage controller. The default of the factory is 0. 1.1 When L1=0, the automatic under-voltage controller can automatically select the under-voltage value according to...

    Yes it's really better with the original controller but i can't connect a kt-lcd3. I made a movie to compare original vs kt controller (i bought two kt controller because i was thinking the first one was faulty). I think the kt controller is power limited by software. FaxFeVE7NaI

    Need help first build with kt-lcd3

    Tested and it's still the same, set P1 to 33, noisy/growling motor. I put back the original controller for now, it works well but it hasn't LCD. So i've just ordered a new sine controller 48v 500w rated current 13A, maximum current 26A compatible with kt-lcd3 display.

    Inside the controller: I've checked all wires from connectors to welds with a multimeter. I reheated the Mosfets welds. AHicks, no i'm not sure, i'm going to try as soon as i will reassemble the controller.

    Need help first build with kt-lcd3

    I made the little tool with 3 leds to know if the motor's sensors are 60° or 120° and it is 60° 120° cause i can see 2 leds lighting at the same time. So C2 need to be set on 2. Edit: My bad, after reading again this post : https://endless-sphere.com/forums/viewtopic.php?t=3484 If 2 leds...

    Need help first build with kt-lcd3

    It's noisy with load and no load. You are certainly right about a defective controller. I don't know if it can be fixed and how. So i need to buy another one, but where ? I need a 48v minimum 22A compatible with kt-lcd3 display. I'm going to play a last time with the 36 possibilitys of the...

    Battery design 48V 13s5p

    Thank you LobbieDove, I correct the error, and change to 15mph for 13S and 16mph for 14S. I do not think autonomy can be calculated as I did. I'm looking for sites: http://www.electricbikerange.info/Electric_bike_range.html http://www.electricbikesimulator.com/calculator.php?language=en#

    Battery design 48V 13s5p

    Ok you are right i didn't read your post properly (i'm french, i don't speak english very well.) So if i want to use the full range of my pack i need a 14s BMS ? And i got to re-organize to easier = 14S4P (56 cells) or harder = 14S5P (70 cells) Isn't there a risk for my controller's motor if i...
