ace27 Posted August 14, 2020 Author Share Posted August 14, 2020 I have also changed the charging port as someone said that might be the problem, still no joy any more advice or recommendation of someone to show might no what I need done Quote Link to comment Share on other sites More sharing options...
RagingGrandpa Posted August 14, 2020 Share Posted August 14, 2020 Carefully check the voltage of the charger output. (Undervoltage = bad charger.) Carefully check the voltage at the charging connector. (Undervoltage = damaged circuits in the wheel.) If you don't know how to carefully measure voltage, ask for in-person assistance from someone who does. "Teaching yourself" on a huge battery pack is a bad idea. More here.

Philip W Posted August 17, 2020 Share Posted August 17, 2020 Just general saying, don't hold my words for it. Just like the grandpa said, first check the charger's voltage. It should be 84v. Then I will open it up and check the battery voltage level. The discharge port (not the charge port) of the battery should still hold a charge. If the battery have no voltage at all, then the battery is bad or the BMS board in it is constantly cutting off. Then I will connect the charger to the EUC and measure the voltage at the charging port of the battery ( not at the charging port of EUC). Of course, never short circuit the 84v battery, especially the discharging port. Handle everything with care! 1 Quote Link to comment Share on other sites More sharing options...
