This is the official Bosch eBike pin cover for all Active / Performance battery terminals. This handy rubber cover simply plugs in where the battery normally sits for protecting the battery pins from dust and corrosion when in transport.
Particularly handy also on dual battery applications where only one battery is fitted, this can cover the second terminal preventing short circuit. Also good when transporting Bosch eBike on cars to protect the metal terminals.
The battery pin cover- it is what it is. Does the job. I take the battery off when my bike goes on the tow bar rack. But I keep losing the pin covers. EBike shop uk charge half the price of Amazon and deliver them the next day. Just in time for the planned ride. Sorted. 👍
