Replacement control board for the 1300wh & 1600wh Msuper v3s+ (84v versions)
This will NOT fit the 67.2v 820wh or 680wh versions of the Msuper V3.
You need to check your motor code (number stamped on the motor), it will start with QJ or HB - this is the HB Version, so the motor code must start with HB not QJ. If it starts with QJ you need the QJ version. (FYI - QJ is 1500w and HB is 2000w)
