E02 over-voltage error, same battery, different controllers

Sort of an old thread, but I found the BMS in the Weize battery I have to cut off charging at 14.0v. So when the Ronogy tries to charge it higher and the BMS opens, it sees an over voltage at the battery terminals and thus the E02. I had to set my controller to only charge to 13.8v to get around the issue with this battery. Just something to
