I have a question about Di2 and traveling. I plan on just pushing my seat down and leaving the battery in and connected. And just unplugging the derailleurs. Am I thinking correctly that if the levers are accidentally activated during travel and the derailleurs are disconnected then the battery shouldn’t drain.

Also looking for opinions on how I’m packing my box. I plan to remove the bars and tie them off to the bike. The bike is mounted firmly by the front and rear dropouts. This is still a work in progress. I plan to reinforce the sides where the rods come thru.

Di2 wiring can be running all sorts of ways inside your frame, stem and bars. So don't forget that the button on the junction box can wake up Di2 also. While some might not see any point in disconnecting the battery or anything else at all, I would disconnect it at the battery. Don't know about your bike but on mine it's too simple just to pull up the saddle and seat post to pull the wire off. Much easier than pulling aside the bar tape and hoods to disconnect mine at the shifters. Which still leaves my bar end junction box connected to the battery... I think. And if I was to only pull the stem with the handlebars on, well there isn't a connection anywhere in the cable going though that, the head tube or the first part of the cable I can pull from the down tube. It's all the way back at the battery or maybe there is one around the BB. I haven't had to search for that one yet.

No idea what the air travel requirements are for this battery. While I'm sure it's okay, you should check to make sure it's legit.

I am pretty sure you have to take the battery out and bring it with you as a carry-on (fire hazard). It is about a 2-second operation (pull out the seat-post, pull the battery out of the seat-post, disconnect the wire from the battery, replace seat-post).

I never removed my battery until a few years ago getting paged while waiting for my flight in Ho Chi Minh City and getting escorted to the bowels of the airport and being asked to remove my bike from the box and remove the battery. Was asked numerous times with the obvious language barrier why was there a battery in the seatpost? All turned out well as it usually does but what a hassle and slightly uncomfortable.

I now always remove my battery.

In general, you don't have to remove a battery for checked baggage if it's installed in the device. Double check on the airlines and/or TSA website. But that's what I've already done with larger batteries than Di2. But if you do remove it, you can't check it, you'll have to put it in your carry on. That said, with my AXS Etap bikes I always just remove them and carry them on to avoid inadvertent activation and drainage. But they're so small and so simple to remove and install.

I would recommend removing the seat post instead of pushing it down. Just my preference. If you push it down and then raise it to the proper height, chances are the exposed portion of the post will now be scratched up. I always remove mine after marking the insertion point with a piece of black electrical tape so it's easy to re-install at the correct height.
