Package arrived well. Everything is in the box. I did not try this one yet. Orders before this one were always good.
First I tought everyting is ok. When connected the battery to the ebike, not working. Charging OK. Mobile app is able to connect and show 4.1 volts on all cells (54 V total). Battery pack output voltage only 17 volts through BMS. Without BMS voltage is 54 volts. Seller not responding after dispute time has finished.
