KS14S Tilt-back After Full Charge - Help
Milli Zhao replied to Marty Backe's topic in Mods, Repairs, & DIY
Hi @Marty Backe, hi everyone, I reported the issue to engineers today, got below solution: 1. our electric unicycle batteries are with over charge protect function inside, similar to mobile, normally won't have any problem even charge 48hours or longer time (even over charge constantly). 2. when the voltage shows on App over 69v, there will be buzzer or voice notice"over voltage" 3. when voltage shows on App above 69v, pls do as follow: 1）record the real voltage shows on App, 2） open the e-unicycle, use a multimeter to check the voltage of the battery packs, 3) compare the two voltage dates, if the gap exceed 0.5v, then need to replace the mainboard. If the gap within 0.5v, no need to care, just restart the device, voltage will turn to normal. 4. if there is over voltage problem, it's not casued by over charge, it's caused by components on mainboard functionally, in fact it's was components influenced unnormally by environment (return the mainbaord to factory to replace the components can fix the problem ) @Marty Backe, can you check the voltage of the battery packs and tell me the datas? Thanks. -
Hi, replied your email with solution to solve the problem. Pls kindly check the email.

Hi,
I'm looking for someone, who can help me with my wheel.
Maybe you could help?
I bought Kingsong KS14S few days ago.
Everything was fine, until today. The wheel suddenly stopped to balance.
It happend, when I was riding. I wasn't riding fast, so got no injuries.
Now if I'm turning it on, the wheel don't stand vertical (it tilts forward and backward,
gyroscope don't lock the wheel).
The battery is about 75%. When I'm turning wheel on, the green lights shining on both sides of the wheel
like nothing is broken. The wheel don't spin if lifted up (motor is not running).
Don't know what happend, I will be grateful for any advice.
SN of my wheel is KS14D4W170825F001,
what wonders me here is why the number starts with KS14D...
like motherboard would be from older wheel?
I bought this wheel from Mr Chenyanming Chen from Aliexpress that has good reputation on this forum.
