• I don't see the point. I just carried my Di2 charging cable with me and could plug it in whenever I thought about it or checked and it showed low batt. Seems pointless/silly wiring it up full time. I wonder if LiIon like being continually trickle charged?

  • Indeed. Seems like a very niche market. The only person I know who has actually let a Di2 battery go flat, to the point it stops working completely, is @Cycliste, and all her electronic devices (phone, tablet, laptop) survive on a maximum charge of about 10%, desperately eeking out their last available electrons. For anyone else, who charges their stuff reasonably regularly, it seems rather overkill.

  • I've flatted mine several times, because I'm idiot and forget to charge.

    I just keep the di2 charger in my frame bag. If di2 dies, I plug charger into USB outlet (dynamo), within 2 minutes of peddling it's working again.

    That bicycle in the photo is a gimmick.

    Di2 battery lasts ~60h.
