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.
Excellent service, part arrived very quickly. I would highly recommend this company.
Bosch eBike Battery Pin Protection Cover
They are tiny, but do the job. I was expecting a large 'plunger' type fit to cover the whole of the bottom of the battery cavity. The Treks do not have a cover when the battery is removed, so my wife has had to make covers. These plugs do protect the pins, but as the pins are quite robust, not 100% sure they are necessary.
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. 👍
