    A must have item

    If you ride a bike with Di2 and live in the northern hemisphere, your bike probably sits undisturbed for the winter months. My battery didn't survive sitting unused in a frigid garage. This winter I plan to take it off the bike and charge it once a month. I am also buying a back up battery just in case.

    Back-up battery!

    Lost my battery on my bikes maiden voyage, wished I'd have this already for a back-up. Did retrace my route and found said lost battery so all was well afterall. Now I have a back-up.

    New Stock Component.

    This is a long lasting required part. It clips into the mount securely and unclips for charging whenever it is needed.

    Old fashioned reliable

    It's the original and it works as specified. Lasts 1,000 plus kilometers. It's still green after 500km
