Kurporious Posted July 20 Posted July 20 I got a problem about my Ninebot one S2 after charge. It went with red and yellow blinking light and it won't work. Please help me to fix it. Thank you. 1 Quote
alcatraz Posted July 22 Posted July 22 I'd guess it's battery pack related considering it's such an old model. Do you feel like opening the pack and see? Quote
Kurporious Posted July 26 Author Posted July 26 May be I''ll try to open it to check the batteries. Thank you! Quote

Chriull Posted July 26 Posted July 26 Could be that EUC World shows single cell voltages? Or https://forum.electricunicycle.org/topic/11685-alexeialexander-have-written-new-ninebattery-app-a-must-have/ ? Don't know if it is still functioning and/or recommendable? 1 Quote
Kurporious Posted July 26 Author Posted July 26 I don't understand how it somehow magically works again Quote
alcatraz Posted July 26 Posted July 26 The bms needs to be connected to the charger for several hours, maybe days, to sort out large imbalances. Maybe that's what happened. It won't however fix what caused the imbalance. With any aging battery pack you can't expect full performance. Ride cautiously below max speed. Quote
