winterwheel Posted September 30, 2019 Share Posted September 30, 2019 We had a KS-16S run down to completely empty on battery and now it seems like it won't take a charge so it's dead in the water. Has anyone else experienced this? Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted September 30, 2019 Share Posted September 30, 2019 What voltage does it show? Quote Link to comment Share on other sites More sharing options...
winterwheel Posted September 30, 2019 Author Share Posted September 30, 2019 The KS app keeps crashing on him, so I've asked him to install WheelLog and see if he can get a connection that way. For now all I can say repeat what he told me: > Ran his wheel down to zero battery (tilt-back occurring at lows speeds coming up a hill). > Connects charger and the LED stays green, rather than turning red to indicate that charging is occurring. It can't be completely zero, because it seems to balance itself but tilt back immediately if he tries to ride it. Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted September 30, 2019 Share Posted September 30, 2019 Some wheels won't let you charge if the voltage is too low. Maybe that's the case. You can always try a multimeter on the battery plug. Quote Link to comment Share on other sites More sharing options...
winterwheel Posted September 30, 2019 Author Share Posted September 30, 2019 That sounds like what is happening; is there any remedy for this? Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted September 30, 2019 Share Posted September 30, 2019 I'm not sure. If the board won't allow the charging, you can just charge the battery packs directly for a bit until their voltage is high enough so the normal charging works again. If it's the BMS, not sure how to get around this. Probably it's only the board. The Z10 had a similar problem being under voltage right after delivery and not charging, you can look up how the affected people dealt with it. - Someone who actually knows should tell you how to proceed Quote Link to comment Share on other sites More sharing options...
winterwheel Posted September 30, 2019 Author Share Posted September 30, 2019 Yes, I'll touch base with KS directly tonight and see what they have to say; just trying to get a jump on things if there is a common/known solution. Thanks, very much appreciated. Quote Link to comment Share on other sites More sharing options...
winterwheel Posted September 30, 2019 Author Share Posted September 30, 2019 Just to wrap this up for the moment, the battery is at 10%, I think the charger may be at fault. Quote Link to comment Share on other sites More sharing options...
