Fitting the right size mount matters more than it might seem: a loose or ill-fitting battery can interrupt the electrical connection and cause erratic shifting, so Shimano specifies this short-size variant for frames that won't accommodate a standard-length mount.\u003c\/p\u003e\n\n\u003cp\u003eIf you're building up a Di2 drivetrain or replacing a worn mount, using the manufacturer-specified hardware is the straightforward way to ensure the system performs as intended. The BM-DN100-S slots into the internal routing cavity and holds the battery correctly positioned for a clean, rattle-free installation.\u003c\/p\u003e\n\n\u003ch3\u003eShimano Di2 BM-DN100-S Short Size Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e BM-DN100-S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e Short (S) — for frames with compact internal battery cavities\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Shimano Di2 internal battery systems\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntended use:\u003c\/strong\u003e Internal frame battery mounting for Di2 electronic drivetrains\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Shimano\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Default Title","offer_id":43705751273516,"sku":"IBMDN100S1","price":155.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/ricycles.com\/products\/shimano-di2-bm-dn100-s-short-size-battery-mount","provider":"RA Cycles","version":"1.0","type":"link"}
