    A critique of mid-drive riding recommendations (and hub drive criticisms)

    Looked long and hard at mid -drive v rear hub. Took advice from a graet bike shop nearby. I was shown chainrings and cassettes swappped out of a mid-drive, and a bike frame with a shattered bottom bracket where the torque of the mid-motor conversion ha broken the down tube welds. I can see the...

    KT LCD3 - Settings for a 60v motor, 60v battery?

    Note of caution here. A lot of components, especially capacitors are rated at 63V, FETs at 60V. Controllers and displays are commodity products and you can bet that minimum allowable component specs apply. The KT series controllers and displays are rated for batteries up to 48V (around 54V...

    KT-22A / LCD8H PAS

    Hi Folks. Problem solved. There is an odd mismatch between the PA Sensor connector pinning and the controller pinning. I now have 3 similar PAS senosors and they all work once the wiring is modified. I worked through the problem as advised by szkuba. The controller was easy enough. The PA...

    KT-22A / LCD8H PAS

    Great advice szkuba, and from amberwolf and AGS. Interesting note abot wire colours. A decent schematic for the controller would be useful. Other project have intervened, and I can zing along on the throttle for now. I will get back on to this though Many thanks.

    KT-22A / LCD8H PAS

    I shall go and check C1 again. I'm sure I tried all the C1 options but worth another pop. Reason I ask about wiring is that I bought a3-way extension cable and split it to make the break out. The wire colours are Red Black and White. When I put a meter across the Red and Black wires I get -5V...

    More KT LCD8H display problems

    I can live with the battery display, though the lvc cut-off makes me anxious. What voltage does your BMS kick in at? I lose power when the display is showing just under 50V. The indicator on the battery shows 1/4- 1/2 full. My big bugbear is the PAS. I have never been able to get it working...

    KT-22A / LCD8H PAS

    Hi, My first question on the forum. I have a KT-22A / LCD8H controller / display diving a Bafang RM G020 500W hub motor, using a 52V 13Ah battery. All is working apart from the PAS, which has never worked. The supplier sent a chain ring side PAS sensor which cannot be fited to the bike unless I...

    More KT LCD8H display problems

    Hi, I have the same problem. If only there was a P setting for nominal battery voltage, rather than a coder's what-if algorithm. I was assured that the KT-22A and LCD8H system would work fine with a 52V battery. It does seem to work ok, (apart from the PAS, but that's another story) however...
