Di2 seat post battery help request.

I have a 2018 Fuji SL2.1 with Di2. To make it easier to fit my bike in the car, I removed the seat and seat post. Now I canít seem to get the seat post battery to connect. What am I doing wrong?

A) To get an e-tube connector to seat--you really need to use the e-tube tool. If you are not already....so presuming you already tried this, and not getting the connector to click....

B) That bike looks like it uses a traditional round post, and coming with Di2 factory stock, I'm guessing it is using a proper Di2 post adapter, and not a ghetto "wrap it in foam and zip-ties mounting.....to get the cable to seat, you'll probably need to yoink the battery free outside the post--so you can get more force to get the connector to click.

C) A clever way to get a round-post mounted Di2 battery free for such purposes....a spare J-bend spoke, the J-bend can reach between the two halves of the adapter and grab onto the battery from behind, and just pull it out.

It is possible, and annoying, that in unplugging things or removing the seatpost, the cable to the battery was unplugged from the junction-B....and fixing that requires yoinking the crankset and BB.

I second what @Marcus_Ti said, use the e-tube wire tool. I've encountered some really hard to "click" connectors that were a real challenge for my fingers. Other than that, it's a pretty simple connection. Make sure there's nothing stuck in each hole and it should click in.
