Di2 Battery Holder for Specialized CG-R

Made by
3D printed in white nylon plastic with a matte finish and slight grainy feel.
Product Description
The fit may not be perfect, or work at all.  We have minimal experience with this seat post.  Once we receive feedback, we may adjust this design. 

This battery holder sleeve is for the Shimano Di2 internal SM-BTR2 or BT-DN110 battery. This battery fits inside the seat post but typically requires a seat post made specifically for Di2.  The holder sleeve allows the battery to be held securely in the 
Specialized CG-R 27.2 mm seat which has rubber Di2 fittings already.  This holder is intended to replace both rubber fittings or can be used to replace just the bottom fitting.

This model is only for a 27.2 mm Specialized CG-R seat post.

IMPORTANT NOTE:  We make Di2 battery holders for other seat posts with various inside diameters.  If you don't have this exact seat post, and the other sizes are not applicable, contact us for a new custom size.

Installation Instructions:
To use this holder, simply place both sides around the battery, with the battery connector end facing the thick lip.  There is a smaller internal groove that holds the battery in place.  Ensure that the battery is locked into that lip, and not simply pressed up against it.  If the battery retracts easily from the holder while held together, it means it isn't engaged with the internal lip.  Hold the assembly together and insert the battery holder assembly into the seat post.  It will require moderate force to insert when you reach the splines.  Once the battery is inserted, it cannot be easily removed by hand.  Use a pair of pliers to grip the thick lip to pull the battery back out.  DO NOT pull the battery out by the battery connector!  If necessary, grip the holder sideways and twist it out until it is out about an inch.  It can then be removed by hand.

See the YouTube video for a demonstration.
