This bracket is a replacement of the bottom part of the battery holder where the battery connects on the frame of the bike. It is the upgraded version that keeps the battery in its place even more securely.
This bracket is attached to the bike frame.
This item is not part of the battery. The last 3 images is the photos of the bottom of the battery where it slides in to this bracket.
This bracket is used on all ERSIN bikes with the large Samsung batteries such as ERSIN1000 range.
