    Surron battery stopped charging

    I have had my surron for around 1400 miles and all of a sudden the battery won't charge past 83. Does anybody know of a way I can fix this?

    83% is only 63 volts, a full charge is a little over 68 volts.
    Use a voltmeter to check what voltage the charger is pushing to start with.
    If the charger voltage is good, the problem is likely a battery or bms failure.

      ^^^What he said. I'd add also checking the actual battery voltage with a voltmeter and comparing it to the percent displayed. Here's a reference pulled from a SurRon thread on here.

        To check the charger output connect it to the battery and compare discharge port voltage with, and without, the charger running.
