The mount is a two-piece cylindrical shell that holds the battery securely within the post, with the cable port oriented downward for a clean exit. PRO includes a removal tool, so retrieving the battery when you need to charge or swap it doesn't require improvisation.\u003c\/p\u003e\n\n\u003cp\u003eTwo size variants cover the most common seatpost diameters — 27.2mm–28.6mm and 30.9mm–31.6mm — making the holder compatible with a wide range of round seatposts beyond PRO's own line. Installation is straightforward: seat the battery in the two-piece holder, feed it into the post cable-end first, and the mount holds it in place without rattling or shifting.\u003c\/p\u003e\n\n\u003ch3\u003ePRO Di2 Internal Battery Holder Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Shimano Di2 internal battery\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSizes available:\u003c\/strong\u003e 27.2mm–28.6mm and 30.9mm–31.6mm seatpost diameter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount design:\u003c\/strong\u003e Two-piece cylindrical shell with cable-port-down orientation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Battery removal tool\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"PRO","offers":[{"title":"Black \/ 27.2mm-28.6mm","offer_id":43516662317100,"sku":"PRAC0094","price":15.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ 30.9mm-31.6mm","offer_id":43516662349868,"sku":"PRAC0095","price":15.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/pro-di2-internal-battery-holder-for-seatpost-3928494.jpg?v=1771299139","url":"https:\/\/ricycles.com\/products\/pro-di2-internal-battery-holder-for-seatpost","provider":"RA Cycles","version":"1.0","type":"link"}
