Battery Anchor by Grintech

Battery anchor by grintech. Designed to hold an eZee flat pack battery to a variety of surfaces such as on a rear bicycle rack, or to the wall of a box bike. 

The eZee battery locks onto this anchor. The anchor is typically screwed or bolted to the part of the bike that the battery should go on. 

Although it does lock on, it is not to be trusted as the only mechanism holding the battery on - the battery can fall off on bumps. Therefore, it needs to also be strapped on.
