Plugging in the charger does not change the voltage of the batteries at all, Ok - so something is not connecting the 84V charger voltage to the batteries. Does the motherboard "forward" the 84V to the batteries charge input? The other possibility is that (one of) the BMS has its charge input protection active (cell overvoltage, defect) and ?disables by the communication wire? all charging!? 41 minutes ago, mozart said: bluetooth devices appear on the phone while the bike is running, kingsong-music connects but ks-18l-3930 does not connect. a message will appear: the pin or key is invalid. This seems ok. The ks-18l-3930 is only for data connections with an app! Quote Link to comment Share on other sites More sharing options...

mozart Posted February 18, 2020 Share Posted February 18, 2020 (edited) Uutta tietoa aiheesta, poistin toisen akun ja lataus alkoi normaalisti. Kytkin senkin jälkeen, kun irrotettu akku aloitti lataamisen, eikä se aiheuttanut ongelmaa, näen hetken kuluttua, onko paristojen jännite tasainen. Mikä voi aiheuttaa tällaisen ongelman akussa? Closed, one cell with two cells broken 0v. Edited February 19, 2020 by mozart Closed 1 Quote Link to comment Share on other sites More sharing options...
