lqwertyd Posted May 14, 2019 Share Posted May 14, 2019 I've had my KS16S for about a month -- maybe a little less. This week I noticed that it has stopped charging. Not sure what to do about it. I've updated the firmware, turned the thing on and off, searched for similar issues on the forums and haven't found anything. Has anyone else had this experience? Thanks!

meepmeepmayer Posted May 14, 2019 Share Posted May 14, 2019 Most likely a broken charger. These things aren't very high quality. Don't worry about your wheel quite yet Or is there anything indicating otherwise? E.g. you can charge, but it stops at 70% or so, that would be a battery problem (do not ride a wheel with a battery problem!). Do you have a multimeter to test the charger? (Standard warning: do not acidentally short your wheel's charge port pins with a multimeter.) Not sure how else to see if a charger still works. Contact your seller, he should be able to help you, too (= most likely send you a new charger and then you see if that was it). 1 Quote Link to comment Share on other sites More sharing options...

Hi, use your mobile phone to send a video to support@szkingsong.com. 1. what's the led indicator? red or green? 2. the device information of the wheel? i would like to see the voltage, serial number, battery level 3. when stop charging? e.g. when the battery level reach 80%, it stop charging, and the battery level isn't increaing any more e.g. when the outout voltage reach 40V, it stop charging, and the voltage isn't increasing any more e.g. after a small hit, the wheel don't charge. this situation may caused by the controller. Different situation, different solutions. 3 1 Quote Link to comment Share on other sites More sharing options...
lqwertyd Posted May 14, 2019 Author Share Posted May 14, 2019 Thanks Michael. I'll send you all the information I can gather. 谢谢你！ Quote Link to comment Share on other sites More sharing options...
Blank Posted May 14, 2019 Share Posted May 14, 2019 I've noticed that the stock charger gets unbearably hot to the touch and as a solution I blow a fan on it when I'm charging. Had the KS16s from Ewheels for over 3 months now and no issues at all with it. Quote Link to comment Share on other sites More sharing options...

Says a certain number of them are defective. 2 Quote Link to comment Share on other sites More sharing options...

Different situation, different solutions. Hello Point 4 has happened to me a week ago, without notice. Now only charge up to 83%. It has one year and 2008km. We tested the batteries and one is fine, but the other is not. I don't understand how it's happened with so little use, one of the batteries has failed a cell. Should I change a battery alone? Is there a problem shooting with it only to 80% battery? I guess if I assume power and autonomy are reduced, I shouldn't have any problems. True?

So the charger is working fine and delivers enough output voltage? Then most presumably at this one pack some cells are bad. Or the cells of the pack are "just" badly misbalanced. Either way, it not only reduces autonomy but every safety margin - so faceplants are more likely. If the cells are already aged and bad, the risk for fire goes up, too. Edit: and going on using this pack will "quite quickly" depriciate/age the misbalanced cells, because they are discharged too low everytime which is "very stressfull" for the cells.

Micheal Shen Posted June 24, 2019 Share Posted June 24, 2019 If battery cell is dead, you'd better to change one battery pack of KS-16S by local distributor or agent. 1 1 Quote Link to comment Share on other sites More sharing options...
vikingbl00d Posted May 18, 2020 Share Posted May 18, 2020 Could use some advice/help. I have had my ks 14M for 2 months now, I just realized why it was going slow and forcing my pedals in the brake position, its low on power. When i plug it in the green light on the charger is staying green as apposed to turning red as if it were charging. I metered the output voltage on the charger at 51 volts and the specd output voltage reads it should be 67 volts so I’m assuming it’s bad? If anyone knows how to figure out what could be wrong and how to potentially fix it I would be most appreciative. I have a new charger on the way but I guess it may be a lengthy wait and I’m jonsing for a ride lol. Thx all sean Quote Link to comment Share on other sites More sharing options...

Your charger has already a quite high deviation - could be something broken. But some/many/most chargers can be adjusted: be carefull with mains voltages! Charger coupd still contain high voltages after beeing unplugged! Quote Link to comment Share on other sites More sharing options...
