Di2 battery in or out during flight
Domestic US flight. Does TSA require it to be removed? Seat post wedge is a pain, so I'd rather leave it in and just push the seat down and unplug the derailleurs or junction box.

You can remove it from the seat-post (or whatever) and put it a carry-on. You can't check batteries, backpacking stoves, fuel, fuel air exposives or gain-of-function virus mutants.

I think they are ok to leave them in the bike and I think you just have to declare it, but yes, check with the airlines.

less than 100wH, installed in a device, OK to check.
less than 100wH, NOT installed in a device, must carry on.
more than 100wH, must carry on, restrictions apply.
the latest di2 battery is a whopping 4 watt hours….. less than half of an iPhone.

Check their regs for CO2 cartridges also.

A lot of different opinions here
Here are the TSA requirements, on the TSA webpage.
and as has already been stated the Shimano Di2 battery is 3.7 Wh, far below the TSA 100 Wh maximum limit for checked baggage.

I think the stumbling block is whether the bike is a device.
It is so easy to take out a seat post battery and carry it with you that I would advise doing that. OTOH, if you box up your bike, it is extremely unlikely they will open it and go looking for a battery.

Barry2 hit the nail on the head. Check with the Security Theater experts at the TSA. They can tell you which ridiculous thing they allow or don't allow in their plays. Last time I had to fly I made sure to double check everything I was carrying and all the various silly rules so I could pass through quickly, though my dumbass put my ticket somewhere else (a spot when I put it there thought would be easy access) and forgot where I put it but eventually found it. I think it is just good practice to double check their rules before you fly.

Will it be a bigger hassle if TSA pages you to come answer some questions about what the battery is to satisfy them that it's an allowed type and you miss your flight?

I'd take the battery out just to avoid the chance of some idiot unpacking the bike to find it because it got picked up by the scanner and they weren't sure what it is.

My son checked his Di2 bike on an airline flight, no questions asked. I don't think the battery issue ever occurred to him. Also, I don't think it would occur to TSA that a bike might have a small battery inside.

The best course is to either simply take it out, or for those who can't turn an Allen wrench, to ask the airline or TSA. Establishing truth by social consensus has its limitations:

The problem with TSA is they can be thugs (or thieves) with badges. You can be technically correct, but they can still make your life miserable, or do damage. The best self defense is to avoid the problem entirely.

Funniest thing I ever saw. To this day I can't imagine that guy ever made his flight...Or any other since for that matter!
