Dudleyellis40 Posted April 13, 2022 Share Posted April 13, 2022 I just lost my old working charger and ordered a new one and the new charger is not working , the battery have been low for a while but the electric unicycle still works perfectly fine. I still ride in front of the house to make sure it work. I opened it up and all the cords look good in great condition and charger port is still clean. I got a 67.2v 2.0A li ion charger and I don’t remember at all what the old charger was. What I do know is I have 2 132wh 2.2ah 60v batteries in the euc. Not sure if I just got wrong charger or if my EUC is broke now and if it’s broke where can I possibly get it fixed or do someone know a solution? 1 Quote Link to comment Share on other sites More sharing options...

What I do know is I have 2 132wh 2.2ah 60v batteries in the euc. 60V sounds like nominal voltage, 16 cells in serie with 2.2Ah make ~132Wh. So a 67.2V charger (max voltage) is right, 2A is a bit much for 2.2Ah li ion cells! For newer cells <0.5C are mostly specified - so a 0.5A or 1A would be right. 14 hours ago, Dudleyellis40 said: Not sure if I just got wrong charger or if my EUC is broke now and if it’s broke where can I possibly get it fixed or do someone know a solution? Maybe the connector has a different pin configuration? Maybe the wheels plug or the following wiring is broken? You habe to check what's broken - were the connection between charger and battery is faulty. What wheel do you have? What's an "Star 1 xiaotu"? 2 Quote Link to comment Share on other sites More sharing options...
