Hi does anyone know the width of the seat post "hole" in a new S3

I'm trying to figure if it's possible to modify a Campagnolo V2 battery to fit inside.

Why would you want to put a Battery in there? (a shimano won't fit) there is more than enough space in the downtube or in the seattube.
Furthermore I would add weight at the lowest place possible.

I've put my di2 battery in my cervelo s5. First make sure you guide the cables down from the seat tube to the bottom bracket. Than create some kind of hook on your battery to make sure you are able to fish it our when needed and the stuff it in your frame with some extra foam around the battery.

That's exactly what I wrote I want to do....in the seat tube. The way the S3 bottom bracket is constructed won't allow me to but the battery in the downtube. I believe the EPS V2 battery is 26 mm in diameter os it won't go in there without modification I know that much. Just trying to get that one measurement in order to determine if it's possible with modification

Can't you let it down through the headtube?

i might, I don't know but I think it's quite unlikely. I really dont see how I'm going to get the battery "around the corner" from head tube to downtube.

@Martin.dk,
The dimension that you ask on your picture is approximately 18.3mm.
I hope that answer your question.

i don't know...yet.

I'm confident that it's possible to modify the battery to fit, I'm just not sure I'm going to buy a S3 frame
