any one have some good ideas on how to put the DI2 battery in an S5, without keeping your battery from rattling?

I put the shimano BTR-2 battery in the seat tube with a layer of bar tape, extra piece of bar tape to take up the remaining space and a zip tie. The long zip tie sticks out of the seat tube when installed so I can easily remove it. I haven’t had any issues with rattling since my seat post prevents everything from moving when installed.

The battery will go down into the seat tube and stop just above the bottle cage mounts. My frame is a 54 so it might be different for larger frames.

Thanks. I will try that out. Ive got a 48 so it may be a tighter fit for me.

Worked perfect!
