    Questions about BMSbattery S06S controller

    I'd have one more quick question pertaining the internals of the S06S controller. What function serves the large capacitor just behind the shunt in lying position (at the left side on the pic) ? What if this cap is missing or without connection ? Thanks! Source: tony16 -...

    Questions about BMSbattery S06S controller

    Thanks d8veh for the insight. Do you possibly know of a 9-FET Sine Wave Controller with max. amps around 18-20A ? Somewhat more powerful than the rather wispy 6-Fet S06s but more compact than a S12s 12-Fet sine wave controller

    Shutoff problem Q100H with KU93 at higher RPMs

    Sorry for the wait. Short version: On the one hand the S06S runs really quiet and smooth with my Q100H 260rpm hub - so the troubles it had with the KU93 new rev. controller - motor cutoff at high RPMs and noisy behaviour of the Q100H - where all controller related! S06S/Q100H combo @ 48V works...

    Questions about BMSbattery S06S controller

    Would have an additional question pertaining the S06S controller with original FETs and caps. (no frankenstein mod yet :mrgreen: ) Does it have a temperature fuse inside or what?! Using it with Li-Ion NiCoMn 48V batt.pack, S-LCD1 display, speed sensor and a Q100H 260rpm hub (52V+ if...

    S12S undocumented connectors

    . will test cruise function via the wire for sure with a S06s controller, coming from a new rev. KU93 controller where it works ok with the cruise control button on a Wuxing-type half grip throttle. That is if those bmsbatt. folks settle to start shipping it eventually :roll:

    S12S undocumented connectors

    . Ok, so then this possibly needs a momentary pushbutton with latching functionality to make it work as cruise control switch with S-series controllers with cruise wire input ..

    S12S undocumented connectors

    . One can connect a 'cruise control button' switch to the cruise wire also and engage or disengage cruise function if needed. It works sort of like a momentary push-button switch. Such cruise control buttons often come accompanied with half/full or thumb grip throttles. In case cruise is engaged...

    Shutoff problem Q100H with KU93 at higher RPMs

    I checked thoroughly all the wiring - phase cables and hall sensor connections - and all is working ok. I even tried all combinations of two phase wires only connected and the motor did not work at all with that configuration. So in essence I reckon my shutoff problems with Q100H 260rpm and...

    Project Interceptor, oil cooled Q100H@55V, in-frame battery

    And so where did you hide the LCD display, dont find it on the pics. It isnt possibly inside the frame also, is it ?! :wink:

    Project Interceptor, oil cooled Q100H@55V, in-frame battery

    Hi Fellow, thanks a lot for the detailed report and pointing out some good and some bad news! The point with the 22km/h speed limit if no display used would be really bad news. :shock: Can you explain a little bit more - with the display you can set the S06S controller to max. speed and max...

    Shutoff problem Q100H with KU93 at higher RPMs

    Thanks for the valuable info fellow. Just recently I did test my Q100H 260rpm + KU93 (new version) in a sensorless test drive - and it was like catastrophe. Every now and then the motor would not turn on at start up or after freewheeling cause the rotor seemingly being in a stalemate position...

    Shutoff problem Q100H with KU93 at higher RPMs

    To partly answer my own question, e-crazyman mailed me that the mentioned 48V 15A controller is having 75NF75 fets against the IRFB3077 with the Infineon controller. 75NF75 obviously having significantly higher Rdson (13 mohm!) compared to the IRFB3077 fets (3.3 mohm !) so the Infineon type...

    Shutoff problem Q100H with KU93 at higher RPMs

    Hi d8veh, do you have the 260rpm version of Q100H or 201rpm version running with the KU63 ? My shutoff problem occurs with Q100H 260rpm version and KU93 at high rpm regards ps. "All my present bikes that I built can be seen here: http://www.pedelecs.co.uk/forum/members/d8veh.html" FYI...

    Shutoff problem Q100H with KU93 at higher RPMs

    .. for low current applications ~15A max. are there any noticeable disadvantages of the e-craze 48V (6fet) controller compared to a IRFB3077 Infineon 6-fet Controller like from EM3ev, other than the infineon being programmable ?

    Shutoff problem Q100H with KU93 at higher RPMs

    Recently had a brief chat online with Jack from bmsbattery whether KU63 is compatible with new Q100H hub motor and if not why not. Answer was no not compatible and it would be too difficult to explain :roll: but basically its too slow for Q100H. Asking if conventional Q100 would be compatible...

    Shutoff problem Q100H with KU93 at higher RPMs

    Hi S06P or S06S controllers are the vendors recommended ones ("most suitable controller") for Q100H hub but designed for 24V-36V batt.packs only. Using them with 48V batt. with >50V off the charger doesn't seem to be a reasonable option. Also KU63 is reported to die off rather quickly when used...

    Shutoff problem Q100H with KU93 at higher RPMs

    Hi wepfi, thanks for the valuable feedback! From your picture posted of the two versions of KU93 I obviously have got the left one being the newer version. You stated that you had the new KU93 tested with Q100 328rpm fast wind motor versions, including the new Q100H version. But from the...

    Shutoff problem Q100H with KU93 at higher RPMs

    As an update report to the Q100H motor shutoff problem, checked the hall-sensor connections and was testdriving again today and the shutoff problem at high motor RPMs is still there. Another thing I experience is that the Q100H at the front gives rather disproportionately loud...

    Shutoff problem Q100H with KU93 at higher RPMs

    Hello Chris, thanks for the advice on ecrazy controller. 15A max current limit would fit the bill. But as mentioned before the q100h having a significant higher reduction-ratio than the q100 so the question would be if that poses a problem again with the eCrazy controller :?: And do you...

    Shutoff problem Q100H with KU93 at higher RPMs

    Thanks for the input guys out of the 100H hub comes a common cable approx. 30cm long - then there is the ominous 9 pin connector (male-female) (seems to be water tight :wink: ) and then more cable approx. ~ 1m long ending with the 3-pase wires and single hall sensor wires. ..looking just...

    Many thanks for the useful infos guys! Did forget to mention I have the 260rpm version of the Q100H hub (-> http://www.bmsbattery.com/front-driving/630-250w350w-q-85100sx-motor-e-bike-kit.html ) and I'm using it laced into a 26" MTB rim (Rigida/Ryde Big Bull) for the front wheel ..
