Yup, easily. Most of the time I was trying to get the battery out of the seatpost that I inadvertently pushed and trying to figure out how to properly place it back.

Also I realized (waaaay too late) that the Di2 system stops working when it is connected to the Etube app. That cost another 15-20mins to take the seatpost out unplug the cables and connect them back.

The whole thing stressed me out for a bit but now I know how to deal with this Di2 software/hardware. If I have to do the same job again it will probably take 10-15mins tops. Good investment!
