  1. Right ! EUC to scooter is for me like downgrading technology... Anyway it looks nice, but I'm not sure what else you can improve on a scooter then just design...
  2. Contact your local KS dealer, they should be able to provide it to you.
  3. Welcome ! So I setup 1 alarm to 25km/h (this is legal limit here for EUc speed) then 2nd to 30km/h and last one to 32Km/h... Anyway in city of Paris going faster then 25km/h is a dream (triaffic ligts, stops, etc). Also I wanted to keep a safe power limit for security reason and for a wheel going almost 50km/h max, half of it sounds safe to me...
  4. Well then it sounds very bad... Almost sure you will have to change the motherboard... I replaced mine already once and it's not so complicated... if you have some basic technical skills, you should be able to change it by yourself...
  5. Also @Marty Backe or @Seba maybe know or know someone who can tells if you can read fault status using on board LEDs...
  6. 1) yes, test fuses... You can probably even see their state because they are usually semi-transparent and you giving high current you should the that wire continuity is gone... 2) try to disconnect motor wires and try to switch it on 3) can you connect to using your phone and KS app ? If you can't then connect charger and try again, you should be able to connect. 4) try with only one batteries. Maybe one one the batteries is bad shape...
  7. My are in english... "please slow down"... Where did you get it from ? maybe you wheel is for chinese market only ?
  8. Just checked on both EUC and KS app and no new firmware... latest is 2.02 for me and I have KS18L (but there is suppose no difference between 18XL and 18L but battery).
  9. Yes it's possible to replace battery pack. You should contact your seller or KS USA and ask if they can provide new battery pack.
  10. well, a full check of your wheel done by a professional maybe the best solution... to me it looks like an issue with motherboard...
  11. Yes it makes sens... The most important is not to overcharge and not let your batteries to discharge to low... As said, it's all question of how the BMS manage batteries, and I have no idea of its algorithm.
  12. @Chriullfor balancing cells, I guess it depends on BMS and how it manage cells... So indeed 100% charge should not be mandatory for cell balancing if BMS manage it properly... I just remember that on a electric scooter app showing per cell voltage, sometimes it was becoming unbalances and the way to fix it was to keep the battery charging for 2h after 100%.
  13. For the 1st charge, I will use original charger delivered with the wheel. Slow charge is less stressful for batteries. It's probably a good idea to use it for 2 or 3 first charge cycles. For 1st charge you can go to 100% then it's a good idea to keep it between 20% and 80% most of the time. You also need to recharge it to 100% sometimes for cells balancing. I do it about once every 2 month... Remember also that discharging under 15% is not a good idea, and should be avoided as much as possible...
  14. I guess it's input = output + heat produced. So I guess it's quite close to 100% efficiency and drop to 0% when both voltages of input and output are equal...
  15. It's mostly about what is on the ground. Looks like synthetic surface is the worst. Happens to me twice in BHV at -1 level :-)
