InnerBarrel Posted September 8, 2022 Share Posted September 8, 2022 Hi there, Thanks in advance and I was wondering: 1 - is this high pitch noise coming from the controller normal? It actually sounds louder in the video https://youtube.com/shorts/H6mU3F8ABY8?feature=share 2 - the BMS is acting very weird i find. 1st, I understand the left and right batteries are connected in parallel. a) How can EUC world and KS app always show 3% difference in charge state between BMS1 and 2? b) in the BMS info section of the KS app, you can see the min Voltage of the whole BMS, let's say the app says 3.168 for the lowest cell voltage, if I look at the individual cell voltages, I can find lower voltages like 3.16 and 3.159. Is this just the app acting up? Thanks I advance 1 Quote Link to comment Share on other sites More sharing options...
Dubardo Posted September 10, 2022 Share Posted September 10, 2022 1. Normal electric noise. Most wheel do that 2.a EUC world use a custom algorithm for battery %. In reality only the Voltage value is true. 2.b Must be a translation error, 3.168 must be an average Quote Link to comment Share on other sites More sharing options...
Celt26 Posted November 10, 2022 Share Posted November 10, 2022 I noticed that my brand new s22 does this when I first turn it on and the lights are in auto light mode it makes the exact same sound. If I turn on the night light and then off the noise goes away. Quote Link to comment Share on other sites More sharing options...
