    Super soco CUx issues

    It was actually disconnected, i guess either bms was faulty or a cell group had issues. I agree on the alarm, been thinking about removing it, especially since users have been reporting issues with it.

    Super soco CUx issues

    I took the battery to a dealer, turns out that battery is under voltage, in three weeks storage not connected to anything, there’s got to be a faulty bms. I’ll get a new battery on warranty. The confusing thing was that the battery showed full on the indicator so i never measured it 😃

    Super soco CUx issues

    Bump! Any Super Soco or CUx owners that recognises thie issue that i have?

    Super soco CUx issues

    Yes, i sure did! It was about 2000$ so not bottom of the bunch.

    Super soco CUx issues

    The whole point of getting this scooter was to avoid making efforts to mod it. Now that is more open 😄 It’s both a blessing and a curse to see the possibilities!

    Super soco CUx issues

    I guess that (as usual) only people with problems post so that the issue percentage is small, but there seems to be more than the normal share of simple issues like poor connections. It’s probably because it’s not premium parts under the covers but still a lot of electronics (with gps, alarm...

    Super soco CUx issues

    I have too many projects so i bought a Super Soco CUx. It’s a nice little scooter, quite small and nimble. EU regulated, 45kph max and something like 2kW. I wanted to have something that just works. Guess what, it doesn’t, after two months of unmodified legal riding.. Fkn hell! This is shorter...

    me1719 and kls7230 and lack of power.

    I guess it’s not this motor since you see the hall signals. Might be a good idea to upload all the info on the kit you bought here.

    me1719 and kls7230 and lack of power.

    Did you run the identification with no chain on, no sprocket? The kellys can be a bit sensitive to load during the id, and it sounds like the hall/phase matching isn’t OK from your description. I’ve had motors that didn’t autoidentify but ran well when matched manually, this can be your next option.

    me1719 and kls7230 and lack of power.

    Most of the stuff you need to know is in the Kelly program manual. Read it to get a basic understanding of the program content. Did you perform the autoidentification yet? it’s done in the ”identify angle” box. Don’t run motor if you didn’t, it can damage the controller.

    Inductance question when connecting 2 batteries in parallel using ideal diodes

    Yes, i think you’re correct, it will be more of an issue but cannot really set it into proportions, not my expertise. I read a thread on rcgroups some years ago where there was spiking visible on a scope with a dual battery plus diode setup. But was it a stopper? Can’t remember.

    Inductance question when connecting 2 batteries in parallel using ideal diodes

    True, there’s a huge thread on rcgroups on this subject. Keep wires as short as possible and as closely bundled together as possible, the wiring loop area sets the inductance created between battery and esc.

    Throttle problem with Votol EM200/2

    Probably a throttle overvolt protection for both of you. Change protection values in the program or add a resistor in the throttle line to lower the voltage into the controller. I would have to spend some time finding it out where to put it and which value, too much work right now but it is...

    Votol Em200-2sp Throttle problems

    can’t say based on the link but easy to verify. Hall sensor throttle signal starts from about 0.7V to about 4V, potentiometer throttle from 0-5V roughly. Or you measure resistance from signal to ground and twist throttle. If it is constant then it’s a hall throttle, if it is linearly changing...

    Votol Em200-2sp Throttle problems

    If you have a potentiometer throttle then that could be the issue. Have you tried it with a hall sensor throttle?

    Ku63 controller at 12s voltage

    Connected PAS, but power is still the same between all assist levels when I use throttle. I don’t know if this is normal, might be that assist levels are only changed on the PAS input since with throttle you could just stop throttling at a lower level. Anyway, the function is not the best for...

    Ku63 controller at 12s voltage

    So, i did the first 100km on the bike and it’s good and bad. The motor core i had turned out to be a high speed winding so at 12s voltage / 26” wheels the noload speed is 50kph. That gets me a power hungry system with about 21A max and 1000w of power - which is kind of fun but was not at all my...

    Ku63 controller at 12s voltage

    Actually my plan was originally to use it as intended, with a 10s battery, but the bms i had could not be configured as 10s - so i built the battery into 12s and fixed the rest😄 main thing was to avoid buying stuff and waiting for a three month shipping delay..

    Ku63 controller at 12s voltage

    I had the KU63 already and it's dirt cheap and simple. I got tired of Votols when they started screwing up the program, guess that might or might not have improved by now but for this build a KU63 was right.

    Ku63 controller at 12s voltage

    Ok, we have rotation! Love it when things come together as they should, even with a motor core that came from a different wheel, a controller for another voltage and a new battery made from scratch in a day. I tinned the shunt without any knowhow on what it should be so if it burns then it might...

    Ku63 controller at 12s voltage

    So.. patience is hard so i tried a fix.. I got an answer from avandalen and it seems the calculation of the r1 value is correct, but the resistor value was rounded down to 270ohm due to availability. Might be good to update that on the page @avandalen 👍 The original resistor on my KU63 was...

    Ku63 controller at 12s voltage

    I have gone full circle from 1000w to 20kW and back to 250w, i’m just building a tootling around bike with a 10 year old ku63 controller that i never used in 2014 😀 I have a 12s battery and the ku63 is 24v/36v (on the label) - but i read here: Re: KU63 KU93 KU123 controller hacking that they...

    Domino throttle wiring

    How is the switch meant to be connected? I guess that if you use a contactor it could break the coil voltage but that shuts down the whole system. If you connect it to break the throttle signal then it might cause a throttle error? Does someone here use it connected and how?

    Selling 25KW Motor + 42 inch Carbon Prop + 28s 500A ESC + 3x7s Battery Banks (21s 45Ah)

    Did you ever fly with it? I am wondering since the stuff i’ve bought from freerchobby has had issues. 25kW is a lot of power.

    LG E78 battery build

    Got the refund for the cells so all was handled OK, even if i lost some time. In the meantime i got the threaded inserts and copper wire for bus bars so i will update my models and do i final test print.
